# Rule: Generating a Product Requirements Document (PRD)
## Goal
To guide an AI assistant in creating a detailed Product Requirements Document (PRD) in Markdown format, based on an initial user prompt. The PRD should be clear, actionable, and suitable for a junior developer to understand and implement the feature.
## Process
1. **Receive Initial Prompt:** The user provides a brief description or request for a new feature or functionality.
2. **Ask Clarifying Questions:** Before writing the PRD, the AI *must* ask clarifying questions to gather sufficient detail. The goal is to understand the "what" and "why" of the feature, not necessarily the "how" (which the developer will figure out).
3. **Generate PRD:** Based on the initial prompt and the user's answers to the clarifying questions, generate a PRD using the structure outlined below.
4. **Save PRD:** Save the generated document as `prd-[feature-name].md` inside the `/tasks` directory.
## Clarifying Questions (Examples)
The AI should adapt its questions based on the prompt, but here are some common areas to explore:
* **Problem/Goal:** "What problem does this feature solve for the user?" or "What is the main goal we want to achieve with this feature?"
* **Target User:** "Who is the primary user of this feature?"
* **Core Functionality:** "Can you describe the key actions a user should be able to perform with this feature?"
* **User Stories:** "Could you provide a few user stories? (e.g., As a [type of user], I want to [perform an action] so that [benefit].)"
* **Acceptance Criteria:** "How will we know when this feature is successfully implemented? What are the key success criteria?"
* **Scope/Boundaries:** "Are there any specific things this feature *should not* do (non-goals)?"
* **Data Requirements:** "What kind of data does this feature need to display or manipulate?"
* **Design/UI:** "Are there any existing design mockups or UI guidelines to follow?" or "Can you describe the desired look and feel?"
* **Edge Cases:** "Are there any potential edge cases or error conditions we should consider?"
## PRD Structure
The generated PRD should include the following sections:
1. **Introduction/Overview:** Briefly describe the feature and the problem it solves. State the goal.
2. **Goals:** List the specific, measurable objectives for this feature.
3. **User Stories:** Detail the user narratives describing feature usage and benefits.
4. **Functional Requirements:** List the specific functionalities the feature must have. Use clear, concise language (e.g., "The system must allow users to upload a profile picture."). Number these requirements.
5. **Non-Goals (Out of Scope):** Clearly state what this feature will *not* include to manage scope.
6. **Design Considerations (Optional):** Link to mockups, describe UI/UX requirements, or mention relevant components/styles if applicable.
7. **Technical Considerations (Optional):** Mention any known technical constraints, dependencies, or suggestions (e.g., "Should integrate with the existing Auth module").
8. **Success Metrics:** How will the success of this feature be measured? (e.g., "Increase user engagement by 10%", "Reduce support tickets related to X").
9. **Open Questions:** List any remaining questions or areas needing further clarification.
## Target Audience
Assume the primary reader of the PRD is a **junior developer**. Therefore, requirements should be explicit, unambiguous, and avoid jargon where possible. Provide enough detail for them to understand the feature's purpose and core logic.
## Output
* **Format:** Markdown (`.md`)
* **Location:** `/tasks/`
* **Filename:** `prd-[feature-name].md`
## Final instructions
1. Do NOT start implmenting the PRD
2. Make sure to ask the user clarifying questions
3. Take the user's answers to the clarifying questions and improve the PRD

# Rule: Generating a Task List from a PRD
## Goal
To guide an AI assistant in creating a detailed, step-by-step task list in Markdown format based on an existing Product Requirements Document (PRD). The task list should guide a developer through implementation.
## Output
- **Format:** Markdown (`.md`)
- **Location:** `/tasks/`
- **Filename:** `tasks-[prd-file-name].md` (e.g., `tasks-prd-user-profile-editing.md`)
## Process
1. **Receive PRD Reference:** The user points the AI to a specific PRD file
2. **Analyze PRD:** The AI reads and analyzes the functional requirements, user stories, and other sections of the specified PRD.
3. **Phase 1: Generate Parent Tasks:** Based on the PRD analysis, create the file and generate the main, high-level tasks required to implement the feature. Use your judgement on how many high-level tasks to use. It's likely to be about 5. Present these tasks to the user in the specified format (without sub-tasks yet). Inform the user: "I have generated the high-level tasks based on the PRD. Ready to generate the sub-tasks? Respond with 'Go' to proceed."
4. **Wait for Confirmation:** Pause and wait for the user to respond with "Go".
5. **Phase 2: Generate Sub-Tasks:** Once the user confirms, break down each parent task into smaller, actionable sub-tasks necessary to complete the parent task. Ensure sub-tasks logically follow from the parent task and cover the implementation details implied by the PRD.
6. **Identify Relevant Files:** Based on the tasks and PRD, identify potential files that will need to be created or modified. List these under the `Relevant Files` section, including corresponding test files if applicable.
7. **Generate Final Output:** Combine the parent tasks, sub-tasks, relevant files, and notes into the final Markdown structure.
8. **Save Task List:** Save the generated document in the `/tasks/` directory with the filename `tasks-[prd-file-name].md`, where `[prd-file-name]` matches the base name of the input PRD file (e.g., if the input was `prd-user-profile-editing.md`, the output is `tasks-prd-user-profile-editing.md`).
## Output Format
The generated task list _must_ follow this structure:
```markdown
## Relevant Files
- `path/to/potential/file1.ts` - Brief description of why this file is relevant (e.g., Contains the main component for this feature).
- `path/to/file1.test.ts` - Unit tests for `file1.ts`.
- `path/to/another/file.tsx` - Brief description (e.g., API route handler for data submission).
- `path/to/another/file.test.tsx` - Unit tests for `another/file.tsx`.
- `lib/utils/helpers.ts` - Brief description (e.g., Utility functions needed for calculations).
- `lib/utils/helpers.test.ts` - Unit tests for `helpers.ts`.
### Notes
- Unit tests should typically be placed alongside the code files they are testing (e.g., `MyComponent.tsx` and `MyComponent.test.tsx` in the same directory).
- Use `npx jest [optional/path/to/test/file]` to run tests. Running without a path executes all tests found by the Jest configuration.
## Tasks
- [ ] 1.0 Parent Task Title
- [ ] 1.1 [Sub-task description 1.1]
- [ ] 1.2 [Sub-task description 1.2]
- [ ] 2.0 Parent Task Title
- [ ] 2.1 [Sub-task description 2.1]
- [ ] 3.0 Parent Task Title (may not require sub-tasks if purely structural or configuration)
```
## Interaction Model
The process explicitly requires a pause after generating parent tasks to get user confirmation ("Go") before proceeding to generate the detailed sub-tasks. This ensures the high-level plan aligns with user expectations before diving into details.
## Target Audience
Assume the primary reader of the task list is a **junior developer** who will implement the feature.

# Task List Management
Guidelines for managing task lists in markdown files to track progress on completing a PRD
## Task Implementation
- **One sub-task at a time:** Do **NOT** start the next subtask until you ask the user for permission and they say “yes” or "y"
- **Completion protocol:**
1. When you finish a **subtask**, immediately mark it as completed by changing `[ ]` to `[x]`.
2. If **all** subtasks underneath a parent task are now `[x]`, also mark the **parent task** as completed.
- Stop after each subtask and wait for the users goahead.
## Task List Maintenance
1. **Update the task list as you work:**
- Mark tasks and subtasks as completed (`[x]`) per the protocol above.
- Add new tasks as they emerge.
2. **Maintain the “Relevant Files” section:**
- List every file created or modified.
- Give each file a oneline description of its purpose.
## AI Instructions
When working with task lists, the AI must:
1. Regularly update the task list file after finishing any significant work.
2. Follow the completion protocol:
- Mark each finished **subtask** `[x]`.
- Mark the **parent task** `[x]` once **all** its subtasks are `[x]`.
3. Add newly discovered tasks.
4. Keep “Relevant Files” accurate and up to date.
5. Before starting work, check which subtask is next.
6. After implementing a subtask, update the file and then pause for user approval.

## 📦 Installation
```bash
# Clone the repository
git clone <repository-url>
cd Cycles
# Install dependencies
pip install -r requirements.txt
# Import the module
from IncrementalTrader import *
```
## 🏃‍♂️ Quick Start
### Basic Strategy Usage
```python
from IncrementalTrader import MetaTrendStrategy, IncTrader
import pandas as pd
# Load your data
data = pd.read_csv('your_data.csv')
# Create strategy
strategy = MetaTrendStrategy("metatrend", params={
"timeframe": "15min",
"supertrend_periods": [10, 20, 30],
"supertrend_multipliers": [2.0, 3.0, 4.0]
})
# Create trader
trader = IncTrader(strategy, initial_usd=10000)
# Process data
for _, row in data.iterrows():
trader.process_data_point(
timestamp=row['timestamp'],
ohlcv=(row['open'], row['high'], row['low'], row['close'], row['volume'])
)
# Get results
results = trader.get_results()
print(f"Final Portfolio Value: ${results['final_portfolio_value']:.2f}")
print(f"Total Return: {results['total_return_pct']:.2f}%")
```
### Backtesting
```python
from IncrementalTrader import IncBacktester, BacktestConfig
# Configure backtest
config = BacktestConfig(
initial_usd=10000,
stop_loss_pct=0.03,
take_profit_pct=0.06,
start_date="2024-01-01",
end_date="2024-12-31"
)
# Run backtest
backtester = IncBacktester()
results = backtester.run_single_strategy(
strategy_class=MetaTrendStrategy,
strategy_params={"timeframe": "15min"},
config=config,
data_file="data/BTCUSDT_1m.csv"
)
# Analyze results
print(f"Sharpe Ratio: {results['performance_metrics']['sharpe_ratio']:.2f}")
print(f"Max Drawdown: {results['performance_metrics']['max_drawdown_pct']:.2f}%")
```
## 📊 Available Strategies
### MetaTrend Strategy
A sophisticated trend-following strategy that uses multiple Supertrend indicators to detect market trends.
```python
strategy = MetaTrendStrategy("metatrend", params={
"timeframe": "15min",
"supertrend_periods": [10, 20, 30],
"supertrend_multipliers": [2.0, 3.0, 4.0],
"min_trend_agreement": 0.6
})
```
### BBRS Strategy
Combines Bollinger Bands and RSI with market regime detection for adaptive trading.
```python
strategy = BBRSStrategy("bbrs", params={
"timeframe": "15min",
"bb_period": 20,
"bb_std": 2.0,
"rsi_period": 14,
"volume_ma_period": 20
})
```
### Random Strategy
A testing strategy that generates random signals for framework validation.
```python
strategy = RandomStrategy("random", params={
"timeframe": "15min",
"buy_probability": 0.1,
"sell_probability": 0.1
})
```
## 🔧 Technical Indicators
All indicators are designed for incremental computation:
```python
from IncrementalTrader.strategies.indicators import *
# Moving Averages
sma = MovingAverageState(period=20)
ema = ExponentialMovingAverageState(period=20, alpha=0.1)
# Volatility
atr = ATRState(period=14)
# Trend
supertrend = SupertrendState(period=10, multiplier=3.0)
# Oscillators
rsi = RSIState(period=14)
bb = BollingerBandsState(period=20, std_dev=2.0)
# Update with new data
for price in price_data:
sma.update(price)
current_sma = sma.get_value()
```
## 🧪 Parameter Optimization
```python
from IncrementalTrader import OptimizationConfig
# Define parameter ranges
param_ranges = {
"supertrend_periods": [[10, 20, 30], [15, 25, 35], [20, 30, 40]],
"supertrend_multipliers": [[2.0, 3.0, 4.0], [1.5, 2.5, 3.5]],
"min_trend_agreement": [0.5, 0.6, 0.7, 0.8]
}
# Configure optimization
opt_config = OptimizationConfig(
base_config=config,
param_ranges=param_ranges,
max_workers=4
)
# Run optimization
results = backtester.optimize_strategy(
strategy_class=MetaTrendStrategy,
optimization_config=opt_config,
data_file="data/BTCUSDT_1m.csv"
)
# Get best parameters
best_params = results['best_params']
best_performance = results['best_performance']
```
## 📈 Performance Analysis
```python
# Get detailed performance metrics
performance = results['performance_metrics']
print(f"Total Trades: {performance['total_trades']}")
print(f"Win Rate: {performance['win_rate']:.2f}%")
print(f"Profit Factor: {performance['profit_factor']:.2f}")
print(f"Sharpe Ratio: {performance['sharpe_ratio']:.2f}")
print(f"Max Drawdown: {performance['max_drawdown_pct']:.2f}%")
print(f"Calmar Ratio: {performance['calmar_ratio']:.2f}")
# Access trade history
trades = results['trades']
for trade in trades[-5:]: # Last 5 trades
print(f"Trade: {trade['side']} at {trade['price']} - P&L: {trade['pnl']:.2f}")
```

### IncStrategySignal
Signal class for strategy outputs.
```python
class IncStrategySignal:
def __init__(self, signal_type: str, confidence: float = 1.0, metadata: dict = None)
```
**Parameters:**
- `signal_type` (str): Signal type ('BUY', 'SELL', 'HOLD')
- `confidence` (float): Signal confidence (0.0 to 1.0)
- `metadata` (dict): Additional signal information
**Factory Methods:**
```python
@classmethod
def BUY(cls, confidence: float = 1.0, metadata: dict = None) -> 'IncStrategySignal'
@classmethod
def SELL(cls, confidence: float = 1.0, metadata: dict = None) -> 'IncStrategySignal'
@classmethod
def HOLD(cls, metadata: dict = None) -> 'IncStrategySignal'
```
**Properties:**
- `signal_type` (str): The signal type
- `confidence` (float): Signal confidence level
- `metadata` (dict): Additional metadata
- `timestamp` (int): Signal generation timestamp
**Example:**
```python
# Create signals using factory methods
buy_signal = IncStrategySignal.BUY(confidence=0.8, metadata={'reason': 'golden_cross'})
sell_signal = IncStrategySignal.SELL(confidence=0.9)
hold_signal = IncStrategySignal.HOLD()
```
### TimeframeAggregator
Aggregates data points to different timeframes.
```python
class TimeframeAggregator:
def __init__(self, timeframe: str)
```
**Parameters:**
- `timeframe` (str): Target timeframe ('1min', '5min', '15min', '30min', '1h', '4h', '1d')
**Methods:**
```python
def add_data_point(self, timestamp: int, ohlcv: tuple) -> tuple | None
"""Add data point and return aggregated OHLCV if timeframe complete."""
def get_current_aggregated(self) -> tuple | None
"""Get current aggregated data without completing timeframe."""
def reset(self) -> None
"""Reset aggregator state."""
```
**Example:**
```python
aggregator = TimeframeAggregator("15min")
for timestamp, ohlcv in data_stream:
aggregated = aggregator.add_data_point(timestamp, ohlcv)
if aggregated:
timestamp_agg, ohlcv_agg = aggregated
# Process aggregated data
```
### IncStrategyBase
Base class for all trading strategies.
```python
class IncStrategyBase:
def __init__(self, name: str, params: dict = None)
```
**Parameters:**
- `name` (str): Strategy name
- `params` (dict): Strategy parameters
**Abstract Methods:**
```python
def _process_aggregated_data(self, timestamp: int, ohlcv: tuple) -> IncStrategySignal
"""Process aggregated data and return signal. Must be implemented by subclasses."""
```
**Public Methods:**
```python
def process_data_point(self, timestamp: int, ohlcv: tuple) -> IncStrategySignal
"""Process raw data point and return signal."""
def get_current_signal(self) -> IncStrategySignal
"""Get the most recent signal."""
def get_performance_metrics(self) -> dict
"""Get strategy performance metrics."""
def reset(self) -> None
"""Reset strategy state."""
```
**Properties:**
- `name` (str): Strategy name
- `params` (dict): Strategy parameters
- `logger` (Logger): Strategy logger
- `signal_history` (list): History of generated signals
**Example:**
```python
class MyStrategy(IncStrategyBase):
def __init__(self, name: str, params: dict = None):
super().__init__(name, params)
self.sma = MovingAverageState(period=20)
def _process_aggregated_data(self, timestamp: int, ohlcv: tuple) -> IncStrategySignal:
_, _, _, close, _ = ohlcv
self.sma.update(close)
if self.sma.is_ready():
return IncStrategySignal.BUY() if close > self.sma.get_value() else IncStrategySignal.SELL()
return IncStrategySignal.HOLD()
```
## Strategy Classes
### MetaTrendStrategy
Multi-Supertrend trend-following strategy.
```python

# Architecture Overview
## Design Philosophy
IncrementalTrader is built around the principle of **incremental computation** - processing new data points efficiently without recalculating the entire history. This approach provides significant performance benefits for real-time trading applications.
### Core Principles
1. **Modularity**: Clear separation of concerns between strategies, execution, and testing
2. **Efficiency**: Constant memory usage and minimal computational overhead
3. **Extensibility**: Easy to add new strategies, indicators, and features
4. **Reliability**: Robust error handling and comprehensive testing
5. **Simplicity**: Clean APIs that are easy to understand and use
## System Architecture

## Component Details
### Strategies Module
The strategies module contains all trading logic and signal generation:
- **Base Classes**: `IncStrategyBase` provides the foundation for all strategies
- **Timeframe Aggregation**: Built-in support for multiple timeframes
- **Signal Generation**: Standardized signal types (BUY, SELL, HOLD)
- **Incremental Indicators**: Memory-efficient technical indicators
#### Strategy Lifecycle
```python
# 1. Initialize strategy with parameters
strategy = MetaTrendStrategy("metatrend", params={"timeframe": "15min"})
# 2. Process data points sequentially
for timestamp, ohlcv in data_stream:
signal = strategy.process_data_point(timestamp, ohlcv)
# 3. Get current state and signals
current_signal = strategy.get_current_signal()
```
### Trader Module
The trader module handles trade execution and position management:
- **Trade Execution**: Converts strategy signals into trades
- **Position Management**: Tracks USD/coin balances and position state
- **Risk Management**: Stop-loss and take-profit handling
- **Performance Tracking**: Real-time performance metrics
#### Trading Workflow
```python
# 1. Create trader with strategy
trader = IncTrader(strategy, initial_usd=10000)
# 2. Process data and execute trades
for timestamp, ohlcv in data_stream:
trader.process_data_point(timestamp, ohlcv)
# 3. Get final results
results = trader.get_results()
```
### Backtester Module
The backtester module provides comprehensive testing capabilities:
- **Single Strategy Testing**: Test individual strategies
- **Parameter Optimization**: Systematic parameter sweeps
- **Multiprocessing**: Parallel execution for faster testing
- **Results Analysis**: Comprehensive performance metrics
#### Backtesting Process
```python
# 1. Configure backtest
config = BacktestConfig(
initial_usd=10000,
stop_loss_pct=0.03,
start_date="2024-01-01",
end_date="2024-12-31"
)
# 2. Run backtest
backtester = IncBacktester()
results = backtester.run_single_strategy(strategy, config)
# 3. Analyze results
performance = results['performance_metrics']
```
## Data Flow
### Real-time Processing
```
Market Data → Strategy → Signal → Trader → Trade Execution
↓ ↓ ↓ ↓ ↓
OHLCV Indicators BUY/SELL Position Portfolio
Data Updates Signals Updates Updates
```
### Backtesting Flow
```
Historical Data → Backtester → Multiple Traders → Results Aggregation
↓ ↓ ↓ ↓
Time Series Strategy Trade Records Performance
OHLCV Instances Collections Metrics
```
## Memory Management
### Incremental Computation
Traditional batch processing recalculates everything for each new data point:
```python
# Batch approach - O(n) memory, O(n) computation
def calculate_sma(prices, period):
return [sum(prices[i:i+period])/period for i in range(len(prices)-period+1)]
```
Incremental approach maintains only necessary state:
```python
# Incremental approach - O(1) memory, O(1) computation
class IncrementalSMA:
def __init__(self, period):
self.period = period
self.values = deque(maxlen=period)
self.sum = 0
def update(self, value):
if len(self.values) == self.period:
self.sum -= self.values[0]
self.values.append(value)
self.sum += value
def get_value(self):
return self.sum / len(self.values) if self.values else 0
```
### Benefits
- **Constant Memory**: Memory usage doesn't grow with data history
- **Fast Updates**: New data points processed in constant time
- **Real-time Capable**: Suitable for live trading applications
- **Scalable**: Performance independent of history length
## Error Handling
### Strategy Level
- Input validation for all parameters
- Graceful handling of missing or invalid data
- Fallback mechanisms for indicator failures
### Trader Level
- Position state validation
- Trade execution error handling
- Balance consistency checks
### System Level
- Comprehensive logging at all levels
- Exception propagation with context
- Recovery mechanisms for transient failures
## Performance Characteristics
### Computational Complexity
| Operation | Batch Approach | Incremental Approach |
|-----------|----------------|---------------------|
| Memory Usage | O(n) | O(1) |
| Update Time | O(n) | O(1) |
| Initialization | O(1) | O(k) where k = warmup period |
### Benchmarks
- **Processing Speed**: ~10x faster than batch recalculation
- **Memory Usage**: ~100x less memory for long histories
- **Latency**: Sub-millisecond processing for new data points
## Extensibility
### Adding New Strategies
1. Inherit from `IncStrategyBase`
2. Implement `process_data_point()` method
3. Return appropriate `IncStrategySignal` objects
4. Register in strategy module
### Adding New Indicators

2. Maintain minimal state for calculations
3. Provide consistent API (update/get_value)
4. Add comprehensive tests
### Integration Points
- **Data Sources**: Easy to connect different data feeds
- **Execution Engines**: Pluggable trade execution backends
- **Risk Management**: Configurable risk management rules
- **Reporting**: Extensible results and analytics framework
## Testing Strategy
### Unit Tests

| Max Drawdown | Maximum peak-to-trough decline | max((Peak - Trough) / Peak) |
| Calmar Ratio | Return to max drawdown ratio | Annualized Return / Max Drawdown |
| Win Rate | Percentage of profitable trades | Winning Trades / Total Trades |
| Profit Factor | Ratio of gross profit to loss | Gross Profit / Gross Loss |
## Parameter Optimization
### Basic Optimization
```python
# Define parameter ranges to test
param_ranges = {
"timeframe": ["5min", "15min", "30min"],
"supertrend_periods": [[10, 20, 30], [15, 25, 35]],
"min_trend_agreement": [0.5, 0.6, 0.7]
}
# Create optimization config
opt_config = OptimizationConfig(
base_config=config,
param_ranges=param_ranges,
max_workers=4,
optimization_metric="sharpe_ratio"
)
# Run optimization
optimization_results = backtester.optimize_strategy(
strategy_class=MetaTrendStrategy,
optimization_config=opt_config,
data_file="data/BTCUSDT_1m.csv"
)
# Get best parameters
best_params = optimization_results['best_params']
best_performance = optimization_results['best_performance']
all_results = optimization_results['all_results']
print(f"Best Parameters: {best_params}")
print(f"Best Sharpe Ratio: {best_performance['sharpe_ratio']:.2f}")
```
### Advanced Optimization
```python
# More complex parameter optimization
param_ranges = {
# Strategy parameters
"timeframe": ["5min", "15min", "30min"],
"supertrend_periods": [
[10, 20, 30], [15, 25, 35], [20, 30, 40],
[10, 15, 20], [25, 35, 45]
],
"supertrend_multipliers": [
[2.0, 3.0, 4.0], [1.5, 2.5, 3.5], [2.5, 3.5, 4.5]
],
"min_trend_agreement": [0.4, 0.5, 0.6, 0.7, 0.8],
# Risk management (will override config values)
"stop_loss_pct": [0.02, 0.03, 0.04, 0.05],
"take_profit_pct": [0.04, 0.06, 0.08, 0.10]
}
# Optimization with custom metric
def custom_metric(performance):
"""Custom optimization metric combining return and drawdown."""
return performance['total_return_pct'] / max(performance['max_drawdown_pct'], 1.0)
opt_config = OptimizationConfig(
base_config=config,
param_ranges=param_ranges,
max_workers=8,
optimization_metric=custom_metric, # Custom function
save_all_results=True
)
results = backtester.optimize_strategy(
strategy_class=MetaTrendStrategy,
optimization_config=opt_config,
data_file="data/BTCUSDT_1m.csv"
)
```
### Optimization Metrics
You can optimize for different metrics:
```python
# Built-in metrics (string names)
optimization_metrics = [
"total_return_pct",
"sharpe_ratio",
"sortino_ratio",
"calmar_ratio",
"profit_factor",
"win_rate"
]
# Custom metric function
def risk_adjusted_return(performance):
return (performance['total_return_pct'] /
max(performance['max_drawdown_pct'], 1.0))
opt_config = OptimizationConfig(
base_config=config,
param_ranges=param_ranges,
optimization_metric=risk_adjusted_return # Custom function
)
```
## Data Management
### Data Format
The backtester expects CSV data with the following columns:
```csv
timestamp,open,high,low,close,volume
1640995200000,46222.5,46850.0,46150.0,46800.0,1250.5
1640995260000,46800.0,47000.0,46750.0,46950.0,980.2
...
```
**Required Columns:**
- `timestamp`: Unix timestamp in milliseconds
- `open`: Opening price
- `high`: Highest price
- `low`: Lowest price
- `close`: Closing price
- `volume`: Trading volume
### Data Loading
```python
# The backtester automatically loads and validates data
results = backtester.run_single_strategy(
strategy_class=MetaTrendStrategy,
strategy_params={"timeframe": "15min"},
config=config,
data_file="data/BTCUSDT_1m.csv" # Automatically loaded and validated
)
# Data is automatically filtered by start_date and end_date from config
```
### Data Validation
The backtester performs automatic data validation:
```python
# Validation checks performed:
# 1. Required columns present
# 2. No missing values
# 3. Timestamps in ascending order
# 4. Price consistency (high >= low, etc.)
# 5. Date range filtering
# 6. Data type validation
```
## Advanced Features
### Custom Strategy Testing
```python
# Test your custom strategy
class MyCustomStrategy(IncStrategyBase):
def __init__(self, name: str, params: dict = None):
super().__init__(name, params)
# Your strategy implementation
def _process_aggregated_data(self, timestamp: int, ohlcv: tuple):
# Your strategy logic
return IncStrategySignal.HOLD()
# Test custom strategy
results = backtester.run_single_strategy(
strategy_class=MyCustomStrategy,
strategy_params={"timeframe": "15min", "custom_param": 42},
config=config,
data_file="data/BTCUSDT_1m.csv"
)
```
### Multiple Strategy Comparison
```python
# Compare different strategies
strategies_to_test = [
(MetaTrendStrategy, {"timeframe": "15min"}),
(BBRSStrategy, {"timeframe": "15min"}),
(RandomStrategy, {"timeframe": "15min"})
]
comparison_results = {}
for strategy_class, params in strategies_to_test:
results = backtester.run_single_strategy(
strategy_class=strategy_class,
strategy_params=params,
config=config,
data_file="data/BTCUSDT_1m.csv"
)
strategy_name = strategy_class.__name__
comparison_results[strategy_name] = results['performance_metrics']
# Compare results
for name, performance in comparison_results.items():
print(f"{name}:")
print(f" Return: {performance['total_return_pct']:.2f}%")
print(f" Sharpe: {performance['sharpe_ratio']:.2f}")
print(f" Max DD: {performance['max_drawdown_pct']:.2f}%")
```
### Walk-Forward Analysis
```python
# Implement walk-forward analysis
import pandas as pd
from datetime import datetime, timedelta
def walk_forward_analysis(strategy_class, params, data_file,
train_months=6, test_months=1):
"""Perform walk-forward analysis."""

end_date = data['timestamp'].max()
results = []
current_date = start_date
while current_date + timedelta(days=30*(train_months + test_months)) <= end_date:
# Define train and test periods
train_start = current_date

return results
# Run walk-forward analysis
wf_results = walk_forward_analysis(
MetaTrendStrategy,
{"timeframe": "15min"},
"data/BTCUSDT_1m.csv"
)
# Analyze walk-forward results
total_returns = [r['performance']['total_return_pct'] for r in wf_results]
avg_return = sum(total_returns) / len(total_returns)
print(f"Average out-of-sample return: {avg_return:.2f}%")
```
## Result Analysis

# Base Indicator Classes
## Overview
All indicators in IncrementalTrader are built on a foundation of base classes that provide common functionality for incremental computation. These base classes ensure consistent behavior, memory efficiency, and real-time capability across all indicators.
## Available indicators
- [Moving Averages](moving_averages.md)
- [Volatility](volatility.md) - ATR
- [Trend](trend.md) - Supertrend
- [Oscillators](oscillators.md) - RSI
- [Bollinger Bands](bollinger_bands.md) - Bollinger Bands
## IndicatorState
The foundation class for all indicators in the framework.
### Features
- **Incremental Computation**: O(1) time complexity per update
- **Constant Memory**: O(1) space complexity regardless of data history
- **State Management**: Maintains internal state efficiently
- **Ready State Tracking**: Indicates when indicator has sufficient data
### Class Definition
```python
from IncrementalTrader.strategies.indicators import IndicatorState
class IndicatorState:
def __init__(self, period: int):
self.period = period
self.data_count = 0
def update(self, value: float):
"""Update indicator with new value."""
raise NotImplementedError("Subclasses must implement update method")
def get_value(self) -> float:
"""Get current indicator value."""
raise NotImplementedError("Subclasses must implement get_value method")
def is_ready(self) -> bool:
"""Check if indicator has enough data."""
return self.data_count >= self.period
def reset(self):
"""Reset indicator state."""
self.data_count = 0
```
### Methods
| Method | Description | Returns |
|--------|-------------|---------|
| `update(value: float)` | Update indicator with new value | None |
| `get_value() -> float` | Get current indicator value | float |
| `is_ready() -> bool` | Check if indicator has enough data | bool |
| `reset()` | Reset indicator state | None |
### Usage Example
```python
class MyCustomIndicator(IndicatorState):
def __init__(self, period: int):
super().__init__(period)
self.sum = 0.0
self.values = []
def update(self, value: float):
self.values.append(value)
self.sum += value
if len(self.values) > self.period:
old_value = self.values.pop(0)
self.sum -= old_value
self.data_count += 1
def get_value(self) -> float:
if not self.is_ready():
return 0.0
return self.sum / min(len(self.values), self.period)
# Usage
indicator = MyCustomIndicator(period=10)
for price in [100, 101, 99, 102, 98]:
indicator.update(price)
if indicator.is_ready():
print(f"Value: {indicator.get_value():.2f}")
```
## SimpleIndicatorState
For indicators that only need the current value and don't require a period.
### Features
- **Immediate Ready**: Always ready after first update
- **No Period Requirement**: Doesn't need historical data
- **Minimal State**: Stores only current value
### Class Definition
```python
class SimpleIndicatorState(IndicatorState):
def __init__(self):
super().__init__(period=1)
self.current_value = 0.0
def update(self, value: float):
self.current_value = value
self.data_count = 1 # Always ready
def get_value(self) -> float:
return self.current_value
```
### Usage Example
```python
# Simple price tracker
price_tracker = SimpleIndicatorState()
for price in [100, 101, 99, 102]:
price_tracker.update(price)
print(f"Current price: {price_tracker.get_value():.2f}")
```
## OHLCIndicatorState
For indicators that require OHLC (Open, High, Low, Close) data instead of just a single price value.
### Features
- **OHLC Data Support**: Handles high, low, close data
- **Flexible Updates**: Can update with individual OHLC components
- **Typical Price Calculation**: Built-in typical price (HLC/3) calculation
### Class Definition
```python
class OHLCIndicatorState(IndicatorState):
def __init__(self, period: int):
super().__init__(period)
self.current_high = 0.0
self.current_low = 0.0
self.current_close = 0.0
def update_ohlc(self, high: float, low: float, close: float):
"""Update with OHLC data."""
self.current_high = high
self.current_low = low
self.current_close = close
self._process_ohlc_data(high, low, close)
self.data_count += 1
def _process_ohlc_data(self, high: float, low: float, close: float):
"""Process OHLC data - to be implemented by subclasses."""
raise NotImplementedError("Subclasses must implement _process_ohlc_data")
def get_typical_price(self) -> float:
"""Calculate typical price (HLC/3)."""
return (self.current_high + self.current_low + self.current_close) / 3.0
def get_true_range(self, prev_close: float = None) -> float:
"""Calculate True Range."""
if prev_close is None:
return self.current_high - self.current_low
return max(
self.current_high - self.current_low,
abs(self.current_high - prev_close),
abs(self.current_low - prev_close)
)
```
### Methods
| Method | Description | Returns |
|--------|-------------|---------|
| `update_ohlc(high, low, close)` | Update with OHLC data | None |
| `get_typical_price()` | Get typical price (HLC/3) | float |
| `get_true_range(prev_close)` | Calculate True Range | float |
### Usage Example
```python
class MyOHLCIndicator(OHLCIndicatorState):
def __init__(self, period: int):
super().__init__(period)
self.hl_sum = 0.0
self.count = 0
def _process_ohlc_data(self, high: float, low: float, close: float):
self.hl_sum += (high - low)
self.count += 1
def get_value(self) -> float:
if self.count == 0:
return 0.0
return self.hl_sum / self.count
# Usage
ohlc_indicator = MyOHLCIndicator(period=10)
ohlc_data = [(105, 95, 100), (108, 98, 102), (110, 100, 105)]
for high, low, close in ohlc_data:
ohlc_indicator.update_ohlc(high, low, close)
if ohlc_indicator.is_ready():
print(f"Average Range: {ohlc_indicator.get_value():.2f}")
print(f"Typical Price: {ohlc_indicator.get_typical_price():.2f}")
```
## Best Practices
### 1. Always Check Ready State
```python
indicator = MovingAverageState(period=20)
for price in price_data:
indicator.update(price)
# Always check if ready before using value
if indicator.is_ready():
value = indicator.get_value()
# Use the value...
```
### 2. Initialize Once, Reuse Many Times
```python
# Good: Initialize once
sma = MovingAverageState(period=20)
# Process many data points
for price in large_dataset:
sma.update(price)
if sma.is_ready():
process_signal(sma.get_value())
# Bad: Don't recreate indicators
for price in large_dataset:
sma = MovingAverageState(period=20) # Wasteful!
sma.update(price)
```
### 3. Handle Edge Cases
```python
def safe_indicator_update(indicator, value):
"""Safely update indicator with error handling."""
try:
if value is not None and not math.isnan(value):
indicator.update(value)
return True
except Exception as e:
logger.error(f"Error updating indicator: {e}")
return False
```
### 4. Batch Updates for Multiple Indicators
```python
# Update all indicators together
indicators = [sma_20, ema_12, rsi_14]
for price in price_stream:
# Update all indicators
for indicator in indicators:
indicator.update(price)
# Check if all are ready
if all(ind.is_ready() for ind in indicators):
# Use all indicator values
values = [ind.get_value() for ind in indicators]
process_signals(values)
```
## Performance Characteristics
### Memory Usage
- **IndicatorState**: O(period) memory usage
- **SimpleIndicatorState**: O(1) memory usage
- **OHLCIndicatorState**: O(period) memory usage
### Processing Speed
- **Update Time**: O(1) per data point for all base classes
- **Value Retrieval**: O(1) for getting current value
- **Ready Check**: O(1) for checking ready state
### Scalability
```python
# Memory usage remains constant regardless of data volume
indicator = MovingAverageState(period=20)
# Process 1 million data points - memory usage stays O(20)
for i in range(1_000_000):
indicator.update(i)
if indicator.is_ready():
value = indicator.get_value() # Always O(1)
```
## Error Handling
### Common Patterns
```python
class RobustIndicator(IndicatorState):
def update(self, value: float):
try:
# Validate input
if value is None or math.isnan(value) or math.isinf(value):
self.logger.warning(f"Invalid value: {value}")
return
# Process value
self._process_value(value)
self.data_count += 1
except Exception as e:
self.logger.error(f"Error in indicator update: {e}")
def get_value(self) -> float:
try:
if not self.is_ready():
return 0.0
return self._calculate_value()
except Exception as e:
self.logger.error(f"Error calculating indicator value: {e}")
return 0.0
```
## Integration with Strategies
### Strategy Usage Pattern
```python
class MyStrategy(IncStrategyBase):
def __init__(self, name: str, params: dict = None):
super().__init__(name, params)
# Initialize indicators
self.sma = MovingAverageState(period=20)
self.rsi = RSIState(period=14)
self.atr = ATRState(period=14)
def _process_aggregated_data(self, timestamp: int, ohlcv: tuple) -> IncStrategySignal:
open_price, high, low, close, volume = ohlcv
# Update all indicators
self.sma.update(close)
self.rsi.update(close)
self.atr.update_ohlc(high, low, close)
# Check if all indicators are ready
if not all([self.sma.is_ready(), self.rsi.is_ready(), self.atr.is_ready()]):
return IncStrategySignal.HOLD()
# Use indicator values for signal generation
sma_value = self.sma.get_value()
rsi_value = self.rsi.get_value()
atr_value = self.atr.get_value()
# Generate signals based on indicator values
return self._generate_signal(close, sma_value, rsi_value, atr_value)
```

# Bollinger Bands Indicators
## Overview
Bollinger Bands are volatility indicators that consist of a moving average (middle band) and two standard deviation bands (upper and lower bands). They help identify overbought/oversold conditions and potential breakout opportunities. IncrementalTrader provides both simple price-based and OHLC-based implementations.
## BollingerBandsState
Standard Bollinger Bands implementation using closing prices and simple moving average.
### Features
- **Three Bands**: Upper, middle (SMA), and lower bands
- **Volatility Measurement**: Bands expand/contract with volatility
- **Mean Reversion Signals**: Price touching bands indicates potential reversal
- **Breakout Detection**: Price breaking through bands signals trend continuation
### Mathematical Formula
```
Middle Band = Simple Moving Average (SMA)
Upper Band = SMA + (Standard Deviation × Multiplier)
Lower Band = SMA - (Standard Deviation × Multiplier)
Standard Deviation = √(Σ(Price - SMA)² / Period)
```
### Class Definition
```python
from IncrementalTrader.strategies.indicators import BollingerBandsState
class BollingerBandsState(IndicatorState):
def __init__(self, period: int, std_dev_multiplier: float = 2.0):
super().__init__(period)
self.std_dev_multiplier = std_dev_multiplier
self.values = []
self.sum = 0.0
self.sum_squares = 0.0
# Band values
self.middle_band = 0.0
self.upper_band = 0.0
self.lower_band = 0.0
def update(self, value: float):
self.values.append(value)
self.sum += value
self.sum_squares += value * value
if len(self.values) > self.period:
old_value = self.values.pop(0)
self.sum -= old_value
self.sum_squares -= old_value * old_value
self.data_count += 1
self._calculate_bands()
def _calculate_bands(self):
if not self.is_ready():
return
n = len(self.values)
# Calculate SMA (middle band)
self.middle_band = self.sum / n
# Calculate standard deviation
variance = (self.sum_squares / n) - (self.middle_band * self.middle_band)
std_dev = math.sqrt(max(variance, 0))
# Calculate upper and lower bands
band_width = std_dev * self.std_dev_multiplier
self.upper_band = self.middle_band + band_width
self.lower_band = self.middle_band - band_width
def get_value(self) -> float:
"""Returns middle band (SMA) value."""
return self.middle_band
def get_upper_band(self) -> float:
return self.upper_band
def get_lower_band(self) -> float:
return self.lower_band
def get_middle_band(self) -> float:
return self.middle_band
def get_band_width(self) -> float:
"""Get the width between upper and lower bands."""
return self.upper_band - self.lower_band
def get_percent_b(self, price: float) -> float:
"""Calculate %B: position of price within the bands."""
if self.get_band_width() == 0:
return 0.5
return (price - self.lower_band) / self.get_band_width()
```
### Usage Examples
#### Basic Bollinger Bands Usage
```python
# Create 20-period Bollinger Bands with 2.0 standard deviation

### Performance Characteristics
- **Time Complexity**: O(1) per update (after initial period)
- **Space Complexity**: O(period)
- **Memory Usage**: ~8 bytes per period + constant overhead
## BollingerBandsOHLCState
OHLC-based Bollinger Bands implementation using typical price (HLC/3) for more accurate volatility measurement.
### Features
- **OHLC Data Support**: Uses high, low, close for typical price calculation
- **Better Volatility Measurement**: More accurate than close-only bands
- **Intraday Analysis**: Accounts for intraday price action
- **Enhanced Signals**: More reliable signals due to complete price information
### Mathematical Formula
```
Typical Price = (High + Low + Close) / 3
Middle Band = SMA(Typical Price)
Upper Band = Middle Band + (Standard Deviation × Multiplier)
Lower Band = Middle Band - (Standard Deviation × Multiplier)
```

## Integration with Strategies
### Bollinger Bands Mean Reversion Strategy
```python
class BollingerMeanReversionStrategy(IncStrategyBase):
def __init__(self, name: str, params: dict = None):

```
## Performance Optimization Tips
### 1. Choose the Right Implementation
```python
# For simple price analysis
bb = BollingerBandsState(period=20, std_dev_multiplier=2.0)
# For comprehensive OHLC analysis
bb_ohlc = BollingerBandsOHLCState(period=20, std_dev_multiplier=2.0)
```
### 2. Optimize Standard Deviation Calculation
```python
# Use incremental variance calculation for better performance
def incremental_variance(sum_val: float, sum_squares: float, count: int, mean: float) -> float:
"""Calculate variance incrementally."""
if count == 0:
return 0.0
return max(0.0, (sum_squares / count) - (mean * mean))
```
### 3. Cache Band Values for Multiple Calculations
```python
class CachedBollingerBands:
def __init__(self, period: int, std_dev: float = 2.0):
self.bb = BollingerBandsState(period, std_dev)
self._cached_bands = None
self._cache_valid = False
def update(self, price: float):
self.bb.update(price)
self._cache_valid = False
def get_bands(self) -> tuple:
if not self._cache_valid:
self._cached_bands = (
self.bb.get_upper_band(),
self.bb.get_middle_band(),
self.bb.get_lower_band()
)
self._cache_valid = True
return self._cached_bands
```

# Moving Average Indicators
## Overview
Moving averages are fundamental trend-following indicators that smooth price data by creating a constantly updated average price. IncrementalTrader provides both Simple Moving Average (SMA) and Exponential Moving Average (EMA) implementations with O(1) time complexity.
## MovingAverageState (SMA)
Simple Moving Average that maintains a rolling window of prices.
### Features
- **O(1) Updates**: Constant time complexity per update
- **Memory Efficient**: Only stores necessary data points
- **Real-time Ready**: Immediate calculation without historical data dependency
### Mathematical Formula
```
SMA = (P₁ + P₂ + ... + Pₙ) / n
Where:
- P₁, P₂, ..., Pₙ are the last n price values
- n is the period
```
### Class Definition
```python
from IncrementalTrader.strategies.indicators import MovingAverageState
class MovingAverageState(IndicatorState):
def __init__(self, period: int):
super().__init__(period)
self.values = []
self.sum = 0.0
def update(self, value: float):
self.values.append(value)
self.sum += value
if len(self.values) > self.period:
old_value = self.values.pop(0)
self.sum -= old_value
self.data_count += 1
def get_value(self) -> float:
if not self.is_ready():
return 0.0
return self.sum / len(self.values)
```
### Usage Examples
#### Basic Usage
```python
# Create 20-period SMA
sma_20 = MovingAverageState(period=20)
# Update with price data
prices = [100, 101, 99, 102, 98, 103, 97, 104]
for price in prices:
sma_20.update(price)
if sma_20.is_ready():
print(f"SMA(20): {sma_20.get_value():.2f}")
```
#### Multiple Timeframes
```python
# Different period SMAs
sma_10 = MovingAverageState(period=10)
sma_20 = MovingAverageState(period=20)
sma_50 = MovingAverageState(period=50)
for price in price_stream:
# Update all SMAs
sma_10.update(price)
sma_20.update(price)
sma_50.update(price)
# Check for golden cross (SMA10 > SMA20)
if all([sma_10.is_ready(), sma_20.is_ready()]):
if sma_10.get_value() > sma_20.get_value():
print("Golden Cross detected!")
```
### Performance Characteristics
- **Time Complexity**: O(1) per update
- **Space Complexity**: O(period)
- **Memory Usage**: ~8 bytes per period (for float values)
## ExponentialMovingAverageState (EMA)
Exponential Moving Average that gives more weight to recent prices.
### Features
- **Exponential Weighting**: Recent prices have more influence
- **O(1) Memory**: Only stores current EMA value and multiplier
- **Responsive**: Reacts faster to price changes than SMA
### Mathematical Formula
```
EMA = (Price × α) + (Previous_EMA × (1 - α))
Where:
- α = 2 / (period + 1) (smoothing factor)
- Price is the current price
- Previous_EMA is the previous EMA value
```
### Class Definition
```python
class ExponentialMovingAverageState(IndicatorState):
def __init__(self, period: int):
super().__init__(period)
self.multiplier = 2.0 / (period + 1)
self.ema_value = 0.0
self.is_first_value = True
def update(self, value: float):
if self.is_first_value:
self.ema_value = value
self.is_first_value = False
else:
self.ema_value = (value * self.multiplier) + (self.ema_value * (1 - self.multiplier))
self.data_count += 1
def get_value(self) -> float:
return self.ema_value
```
### Usage Examples
#### Basic Usage
```python
# Create 12-period EMA
ema_12 = ExponentialMovingAverageState(period=12)
# Update with price data
for price in price_data:
ema_12.update(price)
print(f"EMA(12): {ema_12.get_value():.2f}")
```
#### MACD Calculation
```python
# MACD uses EMA12 and EMA26
ema_12 = ExponentialMovingAverageState(period=12)
ema_26 = ExponentialMovingAverageState(period=26)
macd_values = []
for price in price_data:
ema_12.update(price)
ema_26.update(price)
if ema_26.is_ready(): # EMA26 takes longer to be ready
macd = ema_12.get_value() - ema_26.get_value()
macd_values.append(macd)
print(f"MACD: {macd:.4f}")
```
### Performance Characteristics
- **Time Complexity**: O(1) per update
- **Space Complexity**: O(1)
- **Memory Usage**: ~24 bytes (constant)
## Comparison: SMA vs EMA
| Aspect | SMA | EMA |
|--------|-----|-----|
| **Responsiveness** | Slower | Faster |
| **Memory Usage** | O(period) | O(1) |
| **Smoothness** | Smoother | More volatile |
| **Lag** | Higher lag | Lower lag |
| **Noise Filtering** | Better | Moderate |
### When to Use SMA
- **Trend Identification**: Better for identifying long-term trends
- **Support/Resistance**: More reliable for support and resistance levels
- **Noise Reduction**: Better at filtering out market noise
- **Memory Constraints**: When memory usage is not a concern
### When to Use EMA
- **Quick Signals**: When you need faster response to price changes
- **Memory Efficiency**: When memory usage is critical
- **Short-term Trading**: Better for short-term trading strategies
- **Real-time Systems**: Ideal for high-frequency trading systems
## Advanced Usage Patterns
### Moving Average Crossover Strategy

```
### Adaptive Moving Average
```python
class AdaptiveMovingAverage:
def __init__(self, min_period: int = 5, max_period: int = 50):
self.min_period = min_period
self.max_period = max_period
self.sma_fast = MovingAverageState(min_period)
self.sma_slow = MovingAverageState(max_period)
self.current_ma = MovingAverageState(min_period)
def update(self, price: float):
self.sma_fast.update(price)
self.sma_slow.update(price)
if self.sma_slow.is_ready():
# Calculate volatility-based period
volatility = abs(self.sma_fast.get_value() - self.sma_slow.get_value())
normalized_vol = min(volatility / price, 0.1) # Cap at 10%
# Adjust period based on volatility
adaptive_period = int(self.min_period + (normalized_vol * (self.max_period - self.min_period)))
# Update current MA with adaptive period
if adaptive_period != self.current_ma.period:
self.current_ma = MovingAverageState(adaptive_period)
self.current_ma.update(price)
def get_value(self) -> float:
return self.current_ma.get_value()
def is_ready(self) -> bool:
return self.current_ma.is_ready()
```
## Error Handling and Edge Cases
### Robust Implementation
```python
class RobustMovingAverage(MovingAverageState):
def __init__(self, period: int):
if period <= 0:
raise ValueError("Period must be positive")
super().__init__(period)
def update(self, value: float):
# Validate input
if value is None:
self.logger.warning("Received None value, skipping update")
return
if math.isnan(value) or math.isinf(value):
self.logger.warning(f"Received invalid value: {value}, skipping update")
return
try:
super().update(value)
except Exception as e:
self.logger.error(f"Error updating moving average: {e}")
def get_value(self) -> float:
try:
return super().get_value()
except Exception as e:
self.logger.error(f"Error getting moving average value: {e}")
return 0.0
```
### Handling Missing Data
```python
def update_with_gap_handling(ma: MovingAverageState, value: float, timestamp: int, last_timestamp: int):
"""Update moving average with gap handling for missing data."""
# Define maximum acceptable gap (e.g., 5 minutes)
max_gap = 5 * 60 * 1000 # 5 minutes in milliseconds
if last_timestamp and (timestamp - last_timestamp) > max_gap:
# Large gap detected - reset the moving average
ma.reset()
print(f"Gap detected, resetting moving average")
ma.update(value)
```
## Integration with Strategies
### Strategy Implementation Example
```python
class MovingAverageStrategy(IncStrategyBase):
def __init__(self, name: str, params: dict = None):
super().__init__(name, params)
# Initialize moving averages
self.sma_short = MovingAverageState(self.params.get('short_period', 10))
self.sma_long = MovingAverageState(self.params.get('long_period', 20))
self.ema_signal = ExponentialMovingAverageState(self.params.get('signal_period', 5))
def _process_aggregated_data(self, timestamp: int, ohlcv: tuple) -> IncStrategySignal:
open_price, high, low, close, volume = ohlcv
# Update all moving averages
self.sma_short.update(close)
self.sma_long.update(close)
self.ema_signal.update(close)
# Wait for all indicators to be ready
if not all([self.sma_short.is_ready(), self.sma_long.is_ready(), self.ema_signal.is_ready()]):
return IncStrategySignal.HOLD()
# Get current values
sma_short_val = self.sma_short.get_value()
sma_long_val = self.sma_long.get_value()
ema_signal_val = self.ema_signal.get_value()
# Generate signals
if sma_short_val > sma_long_val and close > ema_signal_val:
confidence = min(0.9, (sma_short_val - sma_long_val) / sma_long_val * 10)
return IncStrategySignal.BUY(confidence=confidence)
elif sma_short_val < sma_long_val and close < ema_signal_val:
confidence = min(0.9, (sma_long_val - sma_short_val) / sma_long_val * 10)
return IncStrategySignal.SELL(confidence=confidence)
return IncStrategySignal.HOLD()
```
## Performance Optimization Tips
### 1. Choose the Right Moving Average
```python
# For memory-constrained environments
ema = ExponentialMovingAverageState(period=20) # O(1) memory
# For better smoothing and trend identification
sma = MovingAverageState(period=20) # O(period) memory
```
### 2. Batch Processing
```python
# Process multiple prices efficiently
def batch_update_moving_averages(mas: list, prices: list):
for price in prices:
for ma in mas:
ma.update(price)
# Return all values at once
return [ma.get_value() for ma in mas if ma.is_ready()]
```
### 3. Avoid Unnecessary Calculations
```python
# Cache ready state to avoid repeated checks
class CachedMovingAverage(MovingAverageState):
def __init__(self, period: int):
super().__init__(period)
self._is_ready_cached = False
def update(self, value: float):
super().update(value)
if not self._is_ready_cached:
self._is_ready_cached = self.data_count >= self.period
def is_ready(self) -> bool:
return self._is_ready_cached
```

# Oscillator Indicators
## Overview
Oscillator indicators help identify overbought and oversold conditions in the market. IncrementalTrader provides RSI (Relative Strength Index) implementations that measure the speed and magnitude of price changes.
## RSIState
Full RSI implementation using Wilder's smoothing method for accurate calculation.
### Features
- **Wilder's Smoothing**: Uses the traditional RSI calculation method
- **Overbought/Oversold**: Clear signals for market extremes
- **Momentum Measurement**: Indicates price momentum strength
- **Divergence Detection**: Helps identify potential trend reversals
### Mathematical Formula
```
RS = Average Gain / Average Loss
RSI = 100 - (100 / (1 + RS))
Where:
- Average Gain = Wilder's smoothing of positive price changes
- Average Loss = Wilder's smoothing of negative price changes
- Wilder's smoothing: ((previous_average × (period - 1)) + current_value) / period
```
### Class Definition
```python
from IncrementalTrader.strategies.indicators import RSIState
class RSIState(IndicatorState):
def __init__(self, period: int):
super().__init__(period)
self.gains = []
self.losses = []
self.avg_gain = 0.0
self.avg_loss = 0.0
self.previous_close = None
self.is_first_calculation = True
def update(self, value: float):
if self.previous_close is not None:
change = value - self.previous_close
gain = max(change, 0.0)
loss = max(-change, 0.0)
if self.is_first_calculation and len(self.gains) >= self.period:
# Initial calculation using simple average
self.avg_gain = sum(self.gains[-self.period:]) / self.period
self.avg_loss = sum(self.losses[-self.period:]) / self.period
self.is_first_calculation = False
elif not self.is_first_calculation:
# Wilder's smoothing
self.avg_gain = ((self.avg_gain * (self.period - 1)) + gain) / self.period
self.avg_loss = ((self.avg_loss * (self.period - 1)) + loss) / self.period
self.gains.append(gain)
self.losses.append(loss)
# Keep only necessary history
if len(self.gains) > self.period:
self.gains.pop(0)
self.losses.pop(0)
self.previous_close = value
self.data_count += 1
def get_value(self) -> float:
if not self.is_ready() or self.avg_loss == 0:
return 50.0 # Neutral RSI
rs = self.avg_gain / self.avg_loss
rsi = 100.0 - (100.0 / (1.0 + rs))
return rsi
def is_ready(self) -> bool:
return self.data_count > self.period and not self.is_first_calculation
```
### Usage Examples
#### Basic RSI Usage
```python
# Create 14-period RSI
rsi_14 = RSIState(period=14)
# Price data
prices = [44, 44.34, 44.09, 44.15, 43.61, 44.33, 44.83, 45.85, 47.25, 47.92, 46.23, 44.18, 46.57, 46.61, 46.5]
for price in prices:
rsi_14.update(price)
if rsi_14.is_ready():
rsi_value = rsi_14.get_value()
print(f"Price: {price:.2f}, RSI(14): {rsi_value:.2f}")
```
#### RSI Trading Signals
```python
class RSISignals:
def __init__(self, period: int = 14, overbought: float = 70.0, oversold: float = 30.0):
self.rsi = RSIState(period)
self.overbought = overbought
self.oversold = oversold
self.previous_rsi = None
def update(self, price: float):
self.rsi.update(price)
def get_signal(self) -> str:
if not self.rsi.is_ready():
return "HOLD"
current_rsi = self.rsi.get_value()
# Oversold bounce signal
if (self.previous_rsi is not None and
self.previous_rsi <= self.oversold and
current_rsi > self.oversold):
signal = "BUY"
# Overbought pullback signal
elif (self.previous_rsi is not None and
self.previous_rsi >= self.overbought and
current_rsi < self.overbought):
signal = "SELL"
else:
signal = "HOLD"
self.previous_rsi = current_rsi
return signal
def get_condition(self) -> str:
"""Get current market condition based on RSI."""
if not self.rsi.is_ready():
return "UNKNOWN"
rsi_value = self.rsi.get_value()
if rsi_value >= self.overbought:
return "OVERBOUGHT"
elif rsi_value <= self.oversold:
return "OVERSOLD"
else:
return "NEUTRAL"
# Usage
rsi_signals = RSISignals(period=14, overbought=70, oversold=30)
for price in prices:
rsi_signals.update(price)
signal = rsi_signals.get_signal()
condition = rsi_signals.get_condition()
if signal != "HOLD":
print(f"RSI Signal: {signal}, Condition: {condition}, Price: {price:.2f}")
```
### Performance Characteristics
- **Time Complexity**: O(1) per update (after initial period)
- **Space Complexity**: O(period)
- **Memory Usage**: ~16 bytes per period + constant overhead
## SimpleRSIState
Simplified RSI implementation using exponential smoothing for memory efficiency.
### Features
- **O(1) Memory**: Constant memory usage regardless of period
- **Exponential Smoothing**: Uses EMA-based calculation
- **Fast Computation**: No need to maintain gain/loss history
- **Approximate RSI**: Close approximation to traditional RSI
### Mathematical Formula
```
Gain = max(price_change, 0)
Loss = max(-price_change, 0)
EMA_Gain = EMA(Gain, period)
EMA_Loss = EMA(Loss, period)
RSI = 100 - (100 / (1 + EMA_Gain / EMA_Loss))
```
### Class Definition
```python
class SimpleRSIState(IndicatorState):
def __init__(self, period: int):
super().__init__(period)
self.alpha = 2.0 / (period + 1)
self.ema_gain = 0.0
self.ema_loss = 0.0
self.previous_close = None
self.is_first_value = True
def update(self, value: float):
if self.previous_close is not None:
change = value - self.previous_close
gain = max(change, 0.0)
loss = max(-change, 0.0)
if self.is_first_value:
self.ema_gain = gain
self.ema_loss = loss
self.is_first_value = False
else:
self.ema_gain = (gain * self.alpha) + (self.ema_gain * (1 - self.alpha))
self.ema_loss = (loss * self.alpha) + (self.ema_loss * (1 - self.alpha))
self.previous_close = value
self.data_count += 1
def get_value(self) -> float:
if not self.is_ready() or self.ema_loss == 0:
return 50.0 # Neutral RSI
rs = self.ema_gain / self.ema_loss
rsi = 100.0 - (100.0 / (1.0 + rs))
return rsi
def is_ready(self) -> bool:
return self.data_count > 1 and not self.is_first_value
```
### Usage Examples
#### Memory-Efficient RSI
```python
# Create memory-efficient RSI
simple_rsi = SimpleRSIState(period=14)
# Process large amounts of data with constant memory
for i, price in enumerate(large_price_dataset):
simple_rsi.update(price)
if i % 1000 == 0 and simple_rsi.is_ready(): # Print every 1000 updates
print(f"RSI after {i} updates: {simple_rsi.get_value():.2f}")
```
#### RSI Divergence Detection
```python
class RSIDivergence:
def __init__(self, period: int = 14, lookback: int = 20):
self.rsi = SimpleRSIState(period)
self.lookback = lookback
self.price_history = []
self.rsi_history = []
def update(self, price: float):
self.rsi.update(price)
if self.rsi.is_ready():
self.price_history.append(price)
self.rsi_history.append(self.rsi.get_value())
# Keep only recent history
if len(self.price_history) > self.lookback:
self.price_history.pop(0)
self.rsi_history.pop(0)
def detect_bullish_divergence(self) -> bool:
"""Detect bullish divergence: price makes lower low, RSI makes higher low."""
if len(self.price_history) < self.lookback:
return False
# Find recent lows
price_low_idx = self.price_history.index(min(self.price_history[-10:]))
rsi_low_idx = self.rsi_history.index(min(self.rsi_history[-10:]))
# Check for divergence pattern
if (price_low_idx < len(self.price_history) - 3 and
rsi_low_idx < len(self.rsi_history) - 3):
recent_price_low = min(self.price_history[-3:])
recent_rsi_low = min(self.rsi_history[-3:])
# Bullish divergence: price lower low, RSI higher low
if (recent_price_low < self.price_history[price_low_idx] and
recent_rsi_low > self.rsi_history[rsi_low_idx]):
return True
return False
def detect_bearish_divergence(self) -> bool:
"""Detect bearish divergence: price makes higher high, RSI makes lower high."""
if len(self.price_history) < self.lookback:
return False
# Find recent highs
price_high_idx = self.price_history.index(max(self.price_history[-10:]))
rsi_high_idx = self.rsi_history.index(max(self.rsi_history[-10:]))
# Check for divergence pattern
if (price_high_idx < len(self.price_history) - 3 and
rsi_high_idx < len(self.rsi_history) - 3):
recent_price_high = max(self.price_history[-3:])
recent_rsi_high = max(self.rsi_history[-3:])
# Bearish divergence: price higher high, RSI lower high
if (recent_price_high > self.price_history[price_high_idx] and
recent_rsi_high < self.rsi_history[rsi_high_idx]):
return True
return False
# Usage
divergence_detector = RSIDivergence(period=14, lookback=20)
for price in price_data:
divergence_detector.update(price)
if divergence_detector.detect_bullish_divergence():
print(f"Bullish RSI divergence detected at price {price:.2f}")
if divergence_detector.detect_bearish_divergence():
print(f"Bearish RSI divergence detected at price {price:.2f}")
```
### Performance Characteristics
- **Time Complexity**: O(1) per update
- **Space Complexity**: O(1)
- **Memory Usage**: ~32 bytes (constant)
## Comparison: RSIState vs SimpleRSIState
| Aspect | RSIState | SimpleRSIState |
|--------|----------|----------------|
| **Memory Usage** | O(period) | O(1) |
| **Calculation Method** | Wilder's Smoothing | Exponential Smoothing |
| **Accuracy** | Higher (traditional) | Good (approximation) |
| **Responsiveness** | Standard | Slightly more responsive |
| **Historical Compatibility** | Traditional RSI | Modern approximation |
### When to Use RSIState
- **Precise Calculations**: When you need exact traditional RSI values
- **Backtesting**: For historical analysis and strategy validation
- **Research**: When studying exact RSI behavior and patterns
- **Small Periods**: When period is small (< 20) and memory isn't an issue
### When to Use SimpleRSIState
- **Memory Efficiency**: When processing large amounts of data
- **Real-time Systems**: For high-frequency trading applications
- **Approximate Analysis**: When close approximation is sufficient
- **Large Periods**: When using large RSI periods (> 50)
## Advanced Usage Patterns
### Multi-Timeframe RSI Analysis
```python
class MultiTimeframeRSI:

### RSI with Dynamic Thresholds
```python
class AdaptiveRSI:

```
## Integration with Strategies
### RSI Mean Reversion Strategy
```python
class RSIMeanReversionStrategy(IncStrategyBase):
def __init__(self, name: str, params: dict = None):
super().__init__(name, params)
# Initialize RSI
self.rsi = RSIState(self.params.get('rsi_period', 14))

# Wait for RSI to be ready
if not self.rsi.is_ready():
return IncStrategySignal.HOLD()

return IncStrategySignal.BUY(confidence=0.5, metadata={'signal_type': 'exit_short'})
self.previous_rsi = current_rsi
return IncStrategySignal.HOLD()
```
## Performance Optimization Tips
### 1. Choose the Right RSI Implementation
```python
# For memory-constrained environments
rsi = SimpleRSIState(period=14) # O(1) memory
# For precise traditional RSI
rsi = RSIState(period=14) # O(period) memory
```
### 2. Batch Processing for Multiple RSIs
```python
def update_multiple_rsis(rsis: list, price: float):
"""Efficiently update multiple RSI indicators."""
for rsi in rsis:
rsi.update(price)
return [rsi.get_value() for rsi in rsis if rsi.is_ready()]
```
### 3. Cache RSI Values for Complex Calculations
```python
class CachedRSI:
def __init__(self, period: int):
self.rsi = SimpleRSIState(period)
self._cached_value = 50.0
self._cache_valid = False
def update(self, price: float):
self.rsi.update(price)
self._cache_valid = False
def get_value(self) -> float:
if not self._cache_valid:
self._cached_value = self.rsi.get_value()
self._cache_valid = True
return self._cached_value
```

# Trend Indicators
## Overview
Trend indicators help identify the direction and strength of market trends. IncrementalTrader provides Supertrend implementations that combine price action with volatility to generate clear trend signals.
## SupertrendState
Individual Supertrend indicator that tracks trend direction and provides support/resistance levels.
### Features
- **Trend Direction**: Clear bullish/bearish trend identification
- **Dynamic Support/Resistance**: Adaptive levels based on volatility
- **ATR-Based**: Uses Average True Range for volatility adjustment
- **Real-time Updates**: Incremental calculation for live trading
### Mathematical Formula
```
Basic Upper Band = (High + Low) / 2 + (Multiplier × ATR)
Basic Lower Band = (High + Low) / 2 - (Multiplier × ATR)
Final Upper Band = Basic Upper Band < Previous Final Upper Band OR Previous Close > Previous Final Upper Band
? Basic Upper Band : Previous Final Upper Band
Final Lower Band = Basic Lower Band > Previous Final Lower Band OR Previous Close < Previous Final Lower Band
? Basic Lower Band : Previous Final Lower Band
Supertrend = Close <= Final Lower Band ? Final Lower Band : Final Upper Band
Trend = Close <= Final Lower Band ? DOWN : UP
```
### Class Definition
```python
from IncrementalTrader.strategies.indicators import SupertrendState
class SupertrendState(OHLCIndicatorState):

### Usage Examples
#### Basic Supertrend Usage
```python
# Create Supertrend with 10-period ATR and 3.0 multiplier
supertrend = SupertrendState(period=10, multiplier=3.0)
# OHLC data: (high, low, close)
ohlc_data = [
(105.0, 102.0, 104.0),
(106.0, 103.0, 105.5),
(107.0, 104.0, 106.0),
(108.0, 105.0, 107.5)
]
for high, low, close in ohlc_data:
supertrend.update_ohlc(high, low, close)
if supertrend.is_ready():
trend_direction = "BULLISH" if supertrend.is_bullish() else "BEARISH"
print(f"Supertrend: {supertrend.get_value():.2f}, Trend: {trend_direction}")
```
#### Trend Change Detection
```python
class SupertrendSignals:
def __init__(self, period: int = 10, multiplier: float = 3.0):

self.previous_trend = None
def update(self, high: float, low: float, close: float):
self.supertrend.update_ohlc(high, low, close)
def get_signal(self) -> str:
if not self.supertrend.is_ready():
return "HOLD"
current_trend = self.supertrend.get_trend()
# Check for trend change
if self.previous_trend is not None and self.previous_trend != current_trend:
if current_trend == 1:
signal = "BUY" # Trend changed to bullish
else:
signal = "SELL" # Trend changed to bearish
else:
signal = "HOLD"
self.previous_trend = current_trend
return signal
def get_support_resistance(self) -> float:
"""Get current support/resistance level."""

signal = signals.get_signal()
support_resistance = signals.get_support_resistance()
if signal != "HOLD":
print(f"Signal: {signal} at {close:.2f}, S/R: {support_resistance:.2f}")
```

## Integration with Strategies
### Supertrend Strategy Example
```python
class SupertrendStrategy(IncStrategyBase):
def __init__(self, name: str, params: dict = None):
super().__init__(name, params)
# Initialize Supertrend collection
configs = self.params.get('supertrend_configs', [(10, 3.0), (14, 2.5), (21, 2.0)])
self.supertrend_collection = SupertrendCollection(configs)
# Strategy parameters
self.min_strength = self.params.get('min_strength', 0.75)
self.previous_consensus = None
def _process_aggregated_data(self, timestamp: int, ohlcv: tuple) -> IncStrategySignal:
open_price, high, low, close, volume = ohlcv
# Update Supertrend collection
self.supertrend_collection.update_ohlc(high, low, close)
# Wait for indicators to be ready
if not self.supertrend_collection.is_ready():
return IncStrategySignal.HOLD()
# Get consensus and strength
current_consensus = self.supertrend_collection.get_consensus_trend()
strength = self.supertrend_collection.get_trend_strength()
# Check for strong consensus change
if (self.previous_consensus is not None and
self.previous_consensus != current_consensus and
strength >= self.min_strength):
if current_consensus == 1:
# Strong bullish consensus
return IncStrategySignal.BUY(
confidence=strength,
metadata={
'consensus': current_consensus,
'strength': strength,
'avg_supertrend': self.supertrend_collection.get_average_supertrend()
}
)
elif current_consensus == -1:
# Strong bearish consensus
return IncStrategySignal.SELL(
confidence=strength,
metadata={
'consensus': current_consensus,
'strength': strength,
'avg_supertrend': self.supertrend_collection.get_average_supertrend()
}
)
self.previous_consensus = current_consensus
return IncStrategySignal.HOLD()
```
## Performance Optimization Tips
### 1. Choose Appropriate Configurations
```python
# For fast signals (more noise)
fast_configs = [(7, 3.0), (10, 2.5)]
# For balanced signals
balanced_configs = [(10, 3.0), (14, 2.5), (21, 2.0)]
# For slow, reliable signals
slow_configs = [(14, 2.0), (21, 1.5), (28, 1.0)]
```
### 2. Optimize Memory Usage
```python
# Use SimpleATRState for memory efficiency
class MemoryEfficientSupertrend(SupertrendState):
def __init__(self, period: int, multiplier: float):
super().__init__(period, multiplier)
# Replace ATRState with SimpleATRState
self.atr = SimpleATRState(period)
```
### 3. Batch Processing
```python
def update_multiple_supertrends(supertrends: list, high: float, low: float, close: float):
"""Efficiently update multiple Supertrend indicators."""
for st in supertrends:
st.update_ohlc(high, low, close)
return [(st.get_value(), st.get_trend()) for st in supertrends if st.is_ready()]
```
---
*Supertrend indicators provide clear trend direction and dynamic support/resistance levels. Use single Supertrend for simple trend following or SupertrendCollection for robust meta-trend analysis.*

# Volatility Indicators
## Overview
Volatility indicators measure the rate of price change and market uncertainty. IncrementalTrader provides Average True Range (ATR) implementations that help assess market volatility and set appropriate stop-loss levels.
## ATRState (Average True Range)
Full ATR implementation that maintains a moving average of True Range values.
### Features
- **True Range Calculation**: Accounts for gaps between trading sessions
- **Volatility Measurement**: Provides absolute volatility measurement
- **Stop-Loss Guidance**: Helps set dynamic stop-loss levels
- **Trend Strength**: Indicates trend strength through volatility
### Mathematical Formula
```
True Range = max(
High - Low,
|High - Previous_Close|,
|Low - Previous_Close|
)
ATR = Moving_Average(True_Range, period)
```
### Class Definition
```python
from IncrementalTrader.strategies.indicators import ATRState
class ATRState(OHLCIndicatorState):
def __init__(self, period: int):
super().__init__(period)
self.true_ranges = []
self.tr_sum = 0.0
self.previous_close = None
def _process_ohlc_data(self, high: float, low: float, close: float):
# Calculate True Range
if self.previous_close is not None:
tr = max(
high - low,
abs(high - self.previous_close),
abs(low - self.previous_close)
)
else:
tr = high - low
# Update True Range moving average
self.true_ranges.append(tr)
self.tr_sum += tr
if len(self.true_ranges) > self.period:
old_tr = self.true_ranges.pop(0)
self.tr_sum -= old_tr
self.previous_close = close
def get_value(self) -> float:
if not self.is_ready():
return 0.0
return self.tr_sum / len(self.true_ranges)
```
### Usage Examples
#### Basic ATR Calculation
```python
# Create 14-period ATR
atr_14 = ATRState(period=14)
# OHLC data: (high, low, close)
ohlc_data = [
(105.0, 102.0, 104.0),
(106.0, 103.0, 105.5),
(107.0, 104.0, 106.0),
(108.0, 105.0, 107.5)
]
for high, low, close in ohlc_data:
atr_14.update_ohlc(high, low, close)
if atr_14.is_ready():
print(f"ATR(14): {atr_14.get_value():.2f}")
```
#### Dynamic Stop-Loss with ATR
```python
class ATRStopLoss:
def __init__(self, atr_period: int = 14, atr_multiplier: float = 2.0):
self.atr = ATRState(atr_period)
self.atr_multiplier = atr_multiplier
def update(self, high: float, low: float, close: float):
self.atr.update_ohlc(high, low, close)
def get_stop_loss(self, entry_price: float, position_type: str) -> float:
if not self.atr.is_ready():
return entry_price * 0.95 if position_type == "LONG" else entry_price * 1.05
atr_value = self.atr.get_value()
if position_type == "LONG":
return entry_price - (atr_value * self.atr_multiplier)
else: # SHORT
return entry_price + (atr_value * self.atr_multiplier)
def get_position_size(self, account_balance: float, risk_percent: float, entry_price: float, position_type: str) -> float:
"""Calculate position size based on ATR risk."""
if not self.atr.is_ready():
return 0.0
risk_amount = account_balance * (risk_percent / 100)
stop_loss = self.get_stop_loss(entry_price, position_type)
risk_per_share = abs(entry_price - stop_loss)
if risk_per_share == 0:
return 0.0
return risk_amount / risk_per_share
# Usage
atr_stop = ATRStopLoss(atr_period=14, atr_multiplier=2.0)
for high, low, close in ohlc_stream:
atr_stop.update(high, low, close)
# Calculate stop loss for a long position
entry_price = close
stop_loss = atr_stop.get_stop_loss(entry_price, "LONG")
position_size = atr_stop.get_position_size(10000, 2.0, entry_price, "LONG")
print(f"Entry: {entry_price:.2f}, Stop: {stop_loss:.2f}, Size: {position_size:.0f}")
```
### Performance Characteristics
- **Time Complexity**: O(1) per update
- **Space Complexity**: O(period)
- **Memory Usage**: ~8 bytes per period + constant overhead
## SimpleATRState
Simplified ATR implementation using exponential smoothing instead of simple moving average.
### Features
- **O(1) Memory**: Constant memory usage regardless of period
- **Exponential Smoothing**: Uses Wilder's smoothing method
- **Faster Computation**: No need to maintain historical True Range values
- **Traditional ATR**: Follows Wilder's original ATR calculation
### Mathematical Formula
```
True Range = max(
High - Low,
|High - Previous_Close|,
|Low - Previous_Close|
)
ATR = (Previous_ATR × (period - 1) + True_Range) / period
```
### Class Definition
```python
class SimpleATRState(OHLCIndicatorState):
def __init__(self, period: int):
super().__init__(period)
self.atr_value = 0.0
self.previous_close = None
self.is_first_value = True
def _process_ohlc_data(self, high: float, low: float, close: float):
# Calculate True Range
if self.previous_close is not None:
tr = max(
high - low,
abs(high - self.previous_close),
abs(low - self.previous_close)
)
else:
tr = high - low
# Update ATR using Wilder's smoothing
if self.is_first_value:
self.atr_value = tr
self.is_first_value = False
else:
self.atr_value = ((self.atr_value * (self.period - 1)) + tr) / self.period
self.previous_close = close
def get_value(self) -> float:
return self.atr_value
```
### Usage Examples
#### Memory-Efficient ATR
```python
# Create memory-efficient ATR
simple_atr = SimpleATRState(period=14)
# Process large amounts of data with constant memory
for i, (high, low, close) in enumerate(large_ohlc_dataset):
simple_atr.update_ohlc(high, low, close)
if i % 1000 == 0: # Print every 1000 updates
print(f"ATR after {i} updates: {simple_atr.get_value():.4f}")
```
#### Volatility Breakout Strategy
```python
class VolatilityBreakout:
def __init__(self, atr_period: int = 14, breakout_multiplier: float = 1.5):
self.atr = SimpleATRState(atr_period)
self.breakout_multiplier = breakout_multiplier
self.previous_close = None
def update(self, high: float, low: float, close: float):
self.atr.update_ohlc(high, low, close)
self.previous_close = close
def get_breakout_levels(self, current_close: float) -> tuple:
"""Get upper and lower breakout levels."""
if not self.atr.is_ready() or self.previous_close is None:
return current_close * 1.01, current_close * 0.99
atr_value = self.atr.get_value()
breakout_distance = atr_value * self.breakout_multiplier
upper_breakout = self.previous_close + breakout_distance
lower_breakout = self.previous_close - breakout_distance
return upper_breakout, lower_breakout
def check_breakout(self, current_high: float, current_low: float, current_close: float) -> str:
"""Check if current price breaks out of volatility range."""
upper_level, lower_level = self.get_breakout_levels(current_close)
if current_high > upper_level:
return "BULLISH_BREAKOUT"
elif current_low < lower_level:
return "BEARISH_BREAKOUT"
return "NO_BREAKOUT"
# Usage
breakout_detector = VolatilityBreakout(atr_period=14, breakout_multiplier=1.5)
for high, low, close in ohlc_data:
breakout_detector.update(high, low, close)
breakout_signal = breakout_detector.check_breakout(high, low, close)
if breakout_signal != "NO_BREAKOUT":
print(f"Breakout detected: {breakout_signal} at {close:.2f}")
```
### Performance Characteristics
- **Time Complexity**: O(1) per update
- **Space Complexity**: O(1)
- **Memory Usage**: ~32 bytes (constant)
## Comparison: ATRState vs SimpleATRState
| Aspect | ATRState | SimpleATRState |
|--------|----------|----------------|
| **Memory Usage** | O(period) | O(1) |
| **Calculation Method** | Simple Moving Average | Exponential Smoothing |
| **Accuracy** | Higher (true SMA) | Good (Wilder's method) |
| **Responsiveness** | Moderate | Slightly more responsive |
| **Historical Compatibility** | Modern | Traditional (Wilder's) |
### When to Use ATRState
- **Precise Calculations**: When you need exact simple moving average of True Range
- **Backtesting**: For historical analysis where memory isn't constrained
- **Research**: When studying exact ATR behavior
- **Small Periods**: When period is small (< 20) and memory isn't an issue
### When to Use SimpleATRState
- **Memory Efficiency**: When processing large amounts of data
- **Real-time Systems**: For high-frequency trading applications
- **Traditional Analysis**: When following Wilder's original methodology
- **Large Periods**: When using large ATR periods (> 50)
## Advanced Usage Patterns
### Multi-Timeframe ATR Analysis
```python
class MultiTimeframeATR:
def __init__(self):
self.atr_short = SimpleATRState(period=7) # Short-term volatility

## Integration with Strategies
### ATR-Enhanced Strategy Example
```python
class ATRTrendStrategy(IncStrategyBase):
def __init__(self, name: str, params: dict = None):
super().__init__(name, params)
# Initialize indicators
self.atr = SimpleATRState(self.params.get('atr_period', 14))
self.sma = MovingAverageState(self.params.get('sma_period', 20))
# ATR parameters
self.atr_stop_multiplier = self.params.get('atr_stop_multiplier', 2.0)
self.atr_entry_multiplier = self.params.get('atr_entry_multiplier', 0.5)
def _process_aggregated_data(self, timestamp: int, ohlcv: tuple) -> IncStrategySignal:
open_price, high, low, close, volume = ohlcv
# Update indicators
self.atr.update_ohlc(high, low, close)
self.sma.update(close)
# Wait for indicators to be ready
if not all([self.atr.is_ready(), self.sma.is_ready()]):
return IncStrategySignal.HOLD()
atr_value = self.atr.get_value()
sma_value = self.sma.get_value()
# Calculate dynamic entry threshold based on ATR
entry_threshold = atr_value * self.atr_entry_multiplier
# Generate signals based on trend and volatility
if close > sma_value + entry_threshold:
# Strong uptrend with sufficient volatility
confidence = min(0.9, (close - sma_value) / atr_value * 0.1)
# Calculate stop loss
stop_loss = close - (atr_value * self.atr_stop_multiplier)
return IncStrategySignal.BUY(
confidence=confidence,
metadata={
'atr_value': atr_value,
'sma_value': sma_value,
'stop_loss': stop_loss,
'entry_threshold': entry_threshold
}
)
elif close < sma_value - entry_threshold:
# Strong downtrend with sufficient volatility
confidence = min(0.9, (sma_value - close) / atr_value * 0.1)
# Calculate stop loss
stop_loss = close + (atr_value * self.atr_stop_multiplier)
return IncStrategySignal.SELL(
confidence=confidence,
metadata={
'atr_value': atr_value,
'sma_value': sma_value,
'stop_loss': stop_loss,
'entry_threshold': entry_threshold
}
)
return IncStrategySignal.HOLD()
```
## Performance Optimization Tips
### 1. Choose the Right ATR Implementation
```python
# For memory-constrained environments
atr = SimpleATRState(period=14) # O(1) memory
# For precise calculations
atr = ATRState(period=14) # O(period) memory
```
### 2. Batch Processing for Multiple ATRs
```python
def update_multiple_atrs(atrs: list, high: float, low: float, close: float):
"""Efficiently update multiple ATR indicators."""
for atr in atrs:
atr.update_ohlc(high, low, close)
return [atr.get_value() for atr in atrs if atr.is_ready()]
```
### 3. Cache ATR Values for Complex Calculations
```python
class CachedATR:
def __init__(self, period: int):
self.atr = SimpleATRState(period)
self._cached_value = 0.0
self._cache_valid = False
def update_ohlc(self, high: float, low: float, close: float):
self.atr.update_ohlc(high, low, close)
self._cache_valid = False
def get_value(self) -> float:
if not self._cache_valid:
self._cached_value = self.atr.get_value()
self._cache_valid = True
return self._cached_value
```
---
*ATR indicators are essential for risk management and volatility analysis. Use ATRState for precise calculations or SimpleATRState for memory efficiency in high-frequency applications.*

# BBRS Strategy Documentation
## Overview
The BBRS (Bollinger Bands + RSI + Squeeze) Strategy is a sophisticated mean-reversion and momentum strategy that combines Bollinger Bands, RSI (Relative Strength Index), and volume analysis to identify optimal entry and exit points. The strategy adapts to different market regimes and uses volume confirmation to improve signal quality.
## Strategy Concept
### Core Philosophy
- **Mean Reversion**: Capitalize on price reversals at Bollinger Band extremes
- **Momentum Confirmation**: Use RSI to confirm oversold/overbought conditions
- **Volume Validation**: Require volume spikes for signal confirmation
- **Market Regime Adaptation**: Adjust parameters based on market conditions
- **Squeeze Detection**: Identify low volatility periods before breakouts
### Key Features
- **Multi-Indicator Fusion**: Combines price, volatility, momentum, and volume
- **Adaptive Thresholds**: Dynamic RSI and Bollinger Band parameters
- **Volume Analysis**: Volume spike detection and moving average tracking
- **Market Regime Detection**: Automatic switching between trending and sideways strategies
- **Squeeze Strategy**: Special handling for Bollinger Band squeeze conditions
## Algorithm Details
### Mathematical Foundation
#### Bollinger Bands Calculation
```
Middle Band (SMA) = Sum(Close, period) / period
Standard Deviation = sqrt(Sum((Close - SMA)²) / period)
Upper Band = Middle Band + (std_dev × Standard Deviation)
Lower Band = Middle Band - (std_dev × Standard Deviation)
%B = (Close - Lower Band) / (Upper Band - Lower Band)
Bandwidth = (Upper Band - Lower Band) / Middle Band
```
#### RSI Calculation (Wilder's Smoothing)
```
Price Change = Close - Previous Close
Gain = Price Change if positive, else 0
Loss = |Price Change| if negative, else 0
Average Gain = Wilder's MA(Gain, period)
Average Loss = Wilder's MA(Loss, period)
RS = Average Gain / Average Loss
RSI = 100 - (100 / (1 + RS))
```
#### Volume Analysis
```
Volume MA = Simple MA(Volume, volume_ma_period)
Volume Spike = Current Volume > (Volume MA × spike_threshold)
Volume Ratio = Current Volume / Volume MA
```

def __init__(self, period: int):
self.period = period
self.gains = deque(maxlen=period)
self.losses = deque(maxlen=period)
self.avg_gain = 0.0

# Wilder's smoothing
if len(self.gains) == self.period:

def _detect_market_regime(self) -> str:
"""Detect current market regime."""
# Check for Bollinger Band squeeze
if self.bb.is_squeeze(threshold=0.1):
return "SQUEEZE"
# Check for trending conditions
bb_bandwidth = self.bb.get_bandwidth()
rsi_value = self.rsi.get_value()
# Trending market indicators

upper, middle, lower = self.bb.get_bands()
rsi_value = self.rsi.get_value()
percent_b = self.bb.get_percent_b(close)
volume_spike = volume > (self.volume_ma.get_value() * self.params['volume_spike_threshold'])
# Generate signals based on regime

## Signal Generation Logic
### Market Regime Strategies
#### 1. Trending Market Strategy
**Entry Conditions:**
- Price < Lower Bollinger Band
- RSI < 50 (momentum confirmation)
- Volume > 1.5× Volume MA (volume spike)
- %B < 0 (price below lower band)
**Exit Conditions:**
- Price > Upper Bollinger Band
- RSI > 70 (overbought)
- %B > 1.0 (price above upper band)
#### 2. Sideways Market Strategy
**Entry Conditions:**
- Price ≤ Lower Bollinger Band
- RSI ≤ 30 (oversold)
- %B ≤ 0.2 (near lower band)
**Exit Conditions:**
- Price ≥ Upper Bollinger Band
- RSI ≥ 70 (overbought)
- %B ≥ 0.8 (near upper band)
#### 3. Squeeze Strategy
**Entry Conditions:**
- Bollinger Band squeeze detected (bandwidth < threshold)
- Price breaks above/below middle band
- Volume spike confirmation
- RSI momentum alignment
**Exit Conditions:**
- Bollinger Bands expand significantly
- Price reaches opposite band
- Volume dies down
### Signal Confidence Calculation
```python
def _calculate_confidence(self, regime: str, conditions_met: list) -> float:
"""Calculate signal confidence based on conditions met."""
base_confidence = {
"TRENDING": 0.7,
"SIDEWAYS": 0.8,
"SQUEEZE": 0.9
}
# Adjust based on conditions met
condition_bonus = len([c for c in conditions_met if c]) * 0.05
return min(1.0, base_confidence[regime] + condition_bonus)
```
### Signal Metadata
Each signal includes comprehensive metadata:
```python
metadata = {
'regime': 'TRENDING', # Market regime
'bb_percent_b': 0.15, # %B indicator value
'rsi_value': 28.5, # Current RSI value
'volume_ratio': 1.8, # Volume vs MA ratio
'bb_bandwidth': 0.12, # Bollinger Band bandwidth
'upper_band': 45234.56, # Upper Bollinger Band
'middle_band': 45000.00, # Middle Bollinger Band (SMA)
'lower_band': 44765.44, # Lower Bollinger Band
'volume_spike': True, # Volume spike detected
'squeeze_detected': False, # Bollinger Band squeeze
'conditions_met': ['price_below_lower', 'rsi_oversold', 'volume_spike'],
'timestamp': 1640995200000 # Signal generation timestamp
}
```
## Performance Characteristics
### Strengths
1. **Mean Reversion Accuracy**: High success rate in ranging markets
2. **Volume Confirmation**: Reduces false signals through volume analysis
3. **Market Adaptation**: Adjusts strategy based on market regime
4. **Multi-Indicator Confirmation**: Combines price, momentum, and volume
5. **Squeeze Detection**: Identifies low volatility breakout opportunities
### Weaknesses
1. **Trending Markets**: May struggle in strong trending conditions
2. **Whipsaws**: Vulnerable to false breakouts in volatile conditions
3. **Parameter Sensitivity**: Performance depends on proper parameter tuning
4. **Lag**: Multiple confirmations can delay entry points
### Optimal Market Conditions
- **Ranging Markets**: Best performance in sideways trading ranges
- **Moderate Volatility**: Works well with normal volatility levels
- **Sufficient Volume**: Requires adequate volume for confirmation
- **Clear Support/Resistance**: Performs best with defined price levels
## Usage Examples

from IncrementalTrader import BBRSStrategy, IncTrader
# Create strategy with default parameters
strategy = BBRSStrategy("bbrs")
# Create trader
trader = IncTrader(strategy, initial_usd=10000)
# Process data
for timestamp, ohlcv in data_stream:
signal = trader.process_data_point(timestamp, ohlcv)
if signal.signal_type != 'HOLD':
print(f"Signal: {signal.signal_type} (confidence: {signal.confidence:.2f})")

})
```
## Advanced Features
### Dynamic Parameter Adjustment
```python
def adjust_parameters_for_volatility(self, volatility: float):
"""Adjust parameters based on market volatility."""
if volatility > 0.03: # High volatility
self.params['bb_std'] = 2.5 # Wider bands
self.params['volume_spike_threshold'] = 2.0 # Higher volume requirement
elif volatility < 0.01: # Low volatility
self.params['bb_std'] = 1.5 # Tighter bands
self.params['volume_spike_threshold'] = 1.2 # Lower volume requirement
```
### Multi-timeframe Analysis
```python
# Combine multiple timeframes for better context
strategy_5m = BBRSStrategy("bbrs_5m", {"timeframe": "5min"})
strategy_15m = BBRSStrategy("bbrs_15m", {"timeframe": "15min"})
strategy_1h = BBRSStrategy("bbrs_1h", {"timeframe": "1h"})
# Use higher timeframe for trend context, lower for entry timing
```
### Custom Regime Detection
```python
def custom_regime_detection(self, price_data: list, volume_data: list) -> str:
"""Custom market regime detection logic."""
# Calculate additional metrics
price_volatility = np.std(price_data[-20:]) / np.mean(price_data[-20:])
volume_trend = np.polyfit(range(10), volume_data[-10:], 1)[0]
# Enhanced regime logic
if price_volatility < 0.01 and self.bb.is_squeeze():
return "SQUEEZE"
elif price_volatility > 0.03 and volume_trend > 0:
return "TRENDING"
else:
return "SIDEWAYS"
```

- **Efficient Calculations**: Incremental updates for all metrics
- **State Management**: Minimal state storage for optimal performance
### Real-time Capability
- **Low Latency**: Fast indicator updates and signal generation
- **Incremental Processing**: Designed for live trading applications
- **Stateful Design**: Maintains indicator state between updates
### Error Handling
```python
def _process_aggregated_data(self, timestamp: int, ohlcv: tuple) -> IncStrategySignal:
try:
# Validate input data
if not self._validate_ohlcv(ohlcv):
self.logger.warning(f"Invalid OHLCV data: {ohlcv}")
return IncStrategySignal.HOLD()
# Validate volume data
if ohlcv[4] <= 0:
self.logger.warning(f"Invalid volume: {ohlcv[4]}")
return IncStrategySignal.HOLD()
# Process data
# ... strategy logic ...
except Exception as e:
self.logger.error(f"Error in BBRS strategy: {e}")
return IncStrategySignal.HOLD()
```
## Troubleshooting
### Common Issues
1. **No Signals Generated**
- Check if RSI thresholds are too extreme
- Verify volume spike threshold is not too high
- Ensure sufficient data for indicator warmup
2. **Too Many False Signals**
- Increase volume spike threshold
- Tighten RSI overbought/oversold levels
- Use wider Bollinger Bands (higher std_dev)
3. **Missed Opportunities**
- Lower volume spike threshold
- Relax RSI thresholds
- Use tighter Bollinger Bands
### Debug Information
```python
# Enable debug logging
strategy.logger.setLevel(logging.DEBUG)
# Access internal state
print(f"Current regime: {strategy._detect_market_regime()}")
print(f"BB bands: {strategy.bb.get_bands()}")
print(f"RSI value: {strategy.rsi.get_value()}")
print(f"Volume ratio: {volume / strategy.volume_ma.get_value()}")
print(f"Squeeze detected: {strategy.bb.is_squeeze()}")
```

# MetaTrend Strategy Documentation
## Overview
The MetaTrend Strategy is a sophisticated trend-following algorithm that uses multiple Supertrend indicators to detect and confirm market trends. By combining signals from multiple Supertrend configurations, it creates a "meta-trend" that provides more reliable trend detection with reduced false signals.
## Strategy Concept
### Core Philosophy
- **Trend Confirmation**: Multiple Supertrend indicators must agree before generating signals
- **False Signal Reduction**: Requires consensus among indicators to filter noise
- **Adaptive Sensitivity**: Different Supertrend configurations capture various trend timeframes
- **Risk Management**: Built-in trend reversal detection for exit signals
### Key Features
- **Multi-Supertrend Analysis**: Uses 3+ Supertrend indicators with different parameters
- **Consensus-Based Signals**: Requires minimum agreement threshold for signal generation
- **Incremental Processing**: O(1) memory and processing time per data point
- **Configurable Parameters**: Flexible configuration for different market conditions
## Algorithm Details
### Mathematical Foundation
The strategy uses multiple Supertrend indicators, each calculated as:
```
Basic Upper Band = (High + Low) / 2 + Multiplier × ATR(Period)
Basic Lower Band = (High + Low) / 2 - Multiplier × ATR(Period)
Final Upper Band = Basic Upper Band < Previous Upper Band OR Previous Close > Previous Upper Band
? Basic Upper Band : Previous Upper Band
Final Lower Band = Basic Lower Band > Previous Lower Band OR Previous Close < Previous Lower Band
? Basic Lower Band : Previous Lower Band
Supertrend = Close <= Final Lower Band ? Final Lower Band : Final Upper Band
Trend Direction = Close <= Final Lower Band ? -1 : 1
```
### Meta-Trend Calculation
```python
# For each Supertrend indicator
for st in supertrend_collection:
if st.is_uptrend():
uptrend_count += 1
elif st.is_downtrend():
downtrend_count += 1
# Calculate agreement ratios
total_indicators = len(supertrend_collection)
uptrend_ratio = uptrend_count / total_indicators
downtrend_ratio = downtrend_count / total_indicators
# Generate meta-signal
if uptrend_ratio >= min_trend_agreement:
meta_signal = "BUY"
elif downtrend_ratio >= min_trend_agreement:
meta_signal = "SELL"
else:
meta_signal = "HOLD"
```

def __init__(self, periods: list, multipliers: list):
# Creates multiple Supertrend indicators
self.supertrends = [
SupertrendState(period, multiplier)
for period, multiplier in zip(periods, multipliers)

```
#### 2. Signal Generation Process
```python
def _process_aggregated_data(self, timestamp: int, ohlcv: tuple) -> IncStrategySignal:
open_price, high, low, close, volume = ohlcv
# Update all Supertrend indicators
self.supertrend_collection.update_ohlc(high, low, close)
# Check if indicators are ready
if not self.supertrend_collection.is_ready():
return IncStrategySignal.HOLD()
# Get meta-signal
meta_signal = self.supertrend_collection.get_meta_signal(
min_agreement=self.params['min_trend_agreement']
)
# Generate strategy signal
if meta_signal == 'BUY' and self.current_signal.signal_type != 'BUY':
return IncStrategySignal.BUY(
confidence=self.supertrend_collection.get_agreement_ratio(),
metadata={
'meta_signal': meta_signal,
'individual_signals': self.supertrend_collection.get_signals(),
'agreement_ratio': self.supertrend_collection.get_agreement_ratio()
}

"timeframe": ["5min", "15min", "30min", "1h"]
}
```
## Signal Generation Logic
### Entry Conditions
**BUY Signal Generated When:**
1. Meta-trend changes from non-bullish to bullish
2. Agreement ratio ≥ `min_trend_agreement`
3. Previous signal was not already BUY
4. All Supertrend indicators are ready
**SELL Signal Generated When:**
1. Meta-trend changes from non-bearish to bearish
2. Agreement ratio ≥ `min_trend_agreement`
3. Previous signal was not already SELL
4. All Supertrend indicators are ready
### Signal Confidence
The confidence level is calculated as the agreement ratio:
```python
confidence = agreeing_indicators / total_indicators
```
- **High Confidence (0.8-1.0)**: Strong consensus among indicators
- **Medium Confidence (0.6-0.8)**: Moderate consensus
- **Low Confidence (0.4-0.6)**: Weak consensus (may not generate signal)
### Signal Metadata
Each signal includes comprehensive metadata:
```python
metadata = {
'meta_signal': 'BUY', # Overall meta-signal
'individual_signals': ['BUY', 'BUY', 'HOLD'], # Individual Supertrend signals
'agreement_ratio': 0.67, # Ratio of agreeing indicators
'supertrend_values': [45123.45, 45234.56, 45345.67], # Current Supertrend values
'trend_directions': [1, 1, 0], # Trend directions (1=up, -1=down, 0=neutral)
'timestamp': 1640995200000 # Signal generation timestamp
}
```
## Performance Characteristics

if not self._validate_ohlcv(ohlcv):
self.logger.warning(f"Invalid OHLCV data: {ohlcv}")
return IncStrategySignal.HOLD()
# Process data
# ... strategy logic ...
except Exception as e:
self.logger.error(f"Error in MetaTrend strategy: {e}")
return IncStrategySignal.HOLD()
```
## Advanced Features
### Dynamic Parameter Adjustment
```python
# Adjust parameters based on market volatility
def adjust_parameters_for_volatility(self, volatility):
if volatility > 0.03: # High volatility
self.params['min_trend_agreement'] = 0.7 # Require more agreement
elif volatility < 0.01: # Low volatility
self.params['min_trend_agreement'] = 0.5 # Allow less agreement
```
### Multi-timeframe Analysis
```python
# Combine multiple timeframes for better signals
strategy_5m = MetaTrendStrategy("mt_5m", {"timeframe": "5min"})
strategy_15m = MetaTrendStrategy("mt_15m", {"timeframe": "15min"})
strategy_1h = MetaTrendStrategy("mt_1h", {"timeframe": "1h"})
# Use higher timeframe for trend direction, lower for entry timing
```
## Troubleshooting
### Common Issues
1. **No Signals Generated**
- Check if `min_trend_agreement` is too high
- Verify sufficient data for indicator warmup
- Ensure data quality and consistency
2. **Too Many False Signals**
- Increase `min_trend_agreement` threshold
- Use wider Supertrend multipliers
- Consider longer timeframes
3. **Delayed Signals**
- Reduce `min_trend_agreement` threshold
- Use shorter Supertrend periods
- Consider faster timeframes
### Debug Information
```python
# Enable debug logging
strategy.logger.setLevel(logging.DEBUG)
# Access internal state
print(f"Current signals: {strategy.supertrend_collection.get_signals()}")
print(f"Agreement ratio: {strategy.supertrend_collection.get_agreement_ratio()}")
print(f"Meta signal: {strategy.supertrend_collection.get_meta_signal()}")
```

# Random Strategy Documentation
## Overview
The Random Strategy is a testing and benchmarking strategy that generates random trading signals. While it may seem counterintuitive, this strategy serves crucial purposes in algorithmic trading: providing a baseline for performance comparison, testing framework robustness, and validating backtesting systems.
## Strategy Concept
### Core Philosophy
- **Baseline Comparison**: Provides a random baseline to compare other strategies against
- **Framework Testing**: Tests the robustness of the trading framework
- **Statistical Validation**: Helps validate that other strategies perform better than random chance
- **System Debugging**: Useful for debugging trading systems and backtesting frameworks
### Key Features
- **Configurable Randomness**: Adjustable probability distributions for signal generation
- **Seed Control**: Reproducible results for testing and validation
- **Signal Frequency Control**: Configurable frequency of signal generation
- **Confidence Simulation**: Realistic confidence levels for testing signal processing
## Algorithm Details
### Mathematical Foundation
The Random Strategy uses probability distributions to generate signals:
```
Signal Generation:
- Generate random number R ~ Uniform(0, 1)
- If R < buy_probability: Generate BUY signal
- Elif R < (buy_probability + sell_probability): Generate SELL signal
- Else: Generate HOLD signal
Confidence Generation:
- Confidence ~ Beta(alpha, beta) or Uniform(min_conf, max_conf)
- Ensures realistic confidence distributions for testing
```
### Signal Distribution
```python
# Default probability distribution
signal_probabilities = {
'BUY': 0.1, # 10% chance of BUY signal
'SELL': 0.1, # 10% chance of SELL signal
'HOLD': 0.8 # 80% chance of HOLD signal
}
# Confidence distribution
confidence_range = (0.5, 0.9) # Realistic confidence levels
```

### Real-time Capability
- **Ultra-Fast**: Minimal processing per data point
- **No Dependencies**: No indicator calculations required
- **Immediate Signals**: Instant signal generation
### Error Handling
```python
def _process_aggregated_data(self, timestamp: int, ohlcv: tuple) -> IncStrategySignal:
try:
# Validate basic data
if not self._validate_ohlcv(ohlcv):
self.logger.warning(f"Invalid OHLCV data: {ohlcv}")
return IncStrategySignal.HOLD()
# Generate random signal
return self._generate_random_signal(timestamp)
except Exception as e:
self.logger.error(f"Error in Random strategy: {e}")
return IncStrategySignal.HOLD()
```
## Testing and Validation
### Framework Testing
```python
def test_signal_distribution():
"""Test that signal distribution matches expected probabilities."""
strategy = RandomStrategy("test", {"seed": 12345})
signals = []
# Generate many signals
for i in range(10000):
signal = strategy._generate_random_signal(i)
signals.append(signal.signal_type)
# Analyze distribution
buy_ratio = signals.count('BUY') / len(signals)
sell_ratio = signals.count('SELL') / len(signals)
hold_ratio = signals.count('HOLD') / len(signals)
assert abs(buy_ratio - 0.1) < 0.02 # Within 2% of expected
assert abs(sell_ratio - 0.1) < 0.02 # Within 2% of expected
assert abs(hold_ratio - 0.8) < 0.02 # Within 2% of expected
```
### Reproducibility Testing
```python
def test_reproducibility():
"""Test that same seed produces same results."""
strategy1 = RandomStrategy("test1", {"seed": 12345})
strategy2 = RandomStrategy("test2", {"seed": 12345})
signals1 = []
signals2 = []
# Generate signals with both strategies
for i in range(1000):
sig1 = strategy1._generate_random_signal(i)
sig2 = strategy2._generate_random_signal(i)
signals1.append((sig1.signal_type, sig1.confidence))
signals2.append((sig2.signal_type, sig2.confidence))
# Should be identical
assert signals1 == signals2
```
## Troubleshooting
### Common Issues
1. **Non-Random Results**
- Check if seed is set (removes randomness)
- Verify probability parameters are correct
- Ensure random number generator is working
2. **Too Many/Few Signals**
- Adjust buy_probability and sell_probability
- Check signal frequency constraints
- Verify timeframe settings
3. **Unrealistic Performance**
- Random strategy should perform around 0% return
- If significantly positive/negative, check for bugs
- Verify transaction costs are included
### Debug Information
```python
# Enable debug logging
strategy.logger.setLevel(logging.DEBUG)
# Check signal statistics
print(f"Total signals generated: {strategy.signal_count}")
print(f"Buy probability: {strategy.params['buy_probability']}")
print(f"Sell probability: {strategy.params['sell_probability']}")
print(f"Current seed: {strategy.params.get('seed', 'None (random)')}")
```
## Integration with Testing Framework
### Benchmark Comparison
```python
def compare_with_random_baseline(strategy_results, random_results):
"""Compare strategy performance against random baseline."""
strategy_return = strategy_results['total_return']
random_return = random_results['total_return']
# Calculate excess return over random
excess_return = strategy_return - random_return
# Statistical significance test
t_stat, p_value = stats.ttest_ind(
strategy_results['daily_returns'],
random_results['daily_returns']
)
return {
'excess_return': excess_return,
'statistical_significance': p_value < 0.05,
't_statistic': t_stat,
'p_value': p_value
}
```
---
*The Random Strategy serves as a crucial testing and benchmarking tool, providing a baseline for performance comparison and validating that other strategies perform better than random chance. While it generates no alpha by design, it's invaluable for framework testing and statistical validation.*

# Strategy Development Guide
This guide explains how to create custom trading strategies using the IncrementalTrader framework.
## Overview
IncrementalTrader strategies are built around the `IncStrategyBase` class, which provides a robust framework for incremental computation, timeframe aggregation, and signal generation.
## Basic Strategy Structure
```python
from IncrementalTrader.strategies.base import IncStrategyBase, IncStrategySignal
from IncrementalTrader.strategies.indicators import MovingAverageState
class MyCustomStrategy(IncStrategyBase):
def __init__(self, name: str, params: dict = None):
super().__init__(name, params)
# Initialize indicators
self.sma_fast = MovingAverageState(period=self.params.get('fast_period', 10))
self.sma_slow = MovingAverageState(period=self.params.get('slow_period', 20))
# Strategy state
self.current_signal = IncStrategySignal.HOLD()
def _process_aggregated_data(self, timestamp: int, ohlcv: tuple) -> IncStrategySignal:
"""Process aggregated data and generate signals."""
open_price, high, low, close, volume = ohlcv
# Update indicators
self.sma_fast.update(close)
self.sma_slow.update(close)
# Generate signals
if self.sma_fast.is_ready() and self.sma_slow.is_ready():
fast_sma = self.sma_fast.get_value()
slow_sma = self.sma_slow.get_value()
if fast_sma > slow_sma and self.current_signal.signal_type != 'BUY':
self.current_signal = IncStrategySignal.BUY(
confidence=0.8,
metadata={'fast_sma': fast_sma, 'slow_sma': slow_sma}
)
elif fast_sma < slow_sma and self.current_signal.signal_type != 'SELL':
self.current_signal = IncStrategySignal.SELL(
confidence=0.8,
metadata={'fast_sma': fast_sma, 'slow_sma': slow_sma}
)
return self.current_signal
```
## Key Components
### 1. Base Class Inheritance
All strategies must inherit from `IncStrategyBase`:
```python
class MyStrategy(IncStrategyBase):
def __init__(self, name: str, params: dict = None):
super().__init__(name, params)
# Your initialization code here
```
### 2. Required Methods
#### `_process_aggregated_data()`
This is the core method where your strategy logic goes:
```python
def _process_aggregated_data(self, timestamp: int, ohlcv: tuple) -> IncStrategySignal:
"""
Process aggregated OHLCV data and return a signal.
Args:
timestamp: Unix timestamp
ohlcv: Tuple of (open, high, low, close, volume)
Returns:
IncStrategySignal: BUY, SELL, or HOLD signal
"""
# Your strategy logic here
return signal
```
### 3. Signal Generation
Use the factory methods to create signals:
```python
# Buy signal
signal = IncStrategySignal.BUY(
confidence=0.8, # Optional: 0.0 to 1.0
metadata={'reason': 'Golden cross detected'} # Optional: additional data
)
# Sell signal
signal = IncStrategySignal.SELL(
confidence=0.9,
metadata={'reason': 'Death cross detected'}
)
# Hold signal
signal = IncStrategySignal.HOLD()
```
## Using Indicators
### Built-in Indicators
IncrementalTrader provides many built-in indicators:
```python
from IncrementalTrader.strategies.indicators import (
MovingAverageState,
ExponentialMovingAverageState,
ATRState,
SupertrendState,
RSIState,
BollingerBandsState
)
class MyStrategy(IncStrategyBase):
def __init__(self, name: str, params: dict = None):
super().__init__(name, params)
# Moving averages
self.sma = MovingAverageState(period=20)
self.ema = ExponentialMovingAverageState(period=20, alpha=0.1)
# Volatility
self.atr = ATRState(period=14)
# Trend
self.supertrend = SupertrendState(period=10, multiplier=3.0)
# Oscillators
self.rsi = RSIState(period=14)
self.bb = BollingerBandsState(period=20, std_dev=2.0)
```
### Indicator Usage Pattern
```python
def _process_aggregated_data(self, timestamp: int, ohlcv: tuple) -> IncStrategySignal:
open_price, high, low, close, volume = ohlcv
# Update indicators
self.sma.update(close)
self.rsi.update(close)
self.atr.update_ohlc(high, low, close)
# Check if indicators are ready
if not (self.sma.is_ready() and self.rsi.is_ready()):
return IncStrategySignal.HOLD()
# Get indicator values
sma_value = self.sma.get_value()
rsi_value = self.rsi.get_value()
atr_value = self.atr.get_value()
# Your strategy logic here
# ...
```
## Advanced Features
### 1. Timeframe Aggregation
The base class automatically handles timeframe aggregation:
```python
class MyStrategy(IncStrategyBase):
def __init__(self, name: str, params: dict = None):
# Set timeframe in params
default_params = {"timeframe": "15min"}
if params:
default_params.update(params)
super().__init__(name, default_params)
```
Supported timeframes:
- `"1min"`, `"5min"`, `"15min"`, `"30min"`
- `"1h"`, `"4h"`, `"1d"`
### 2. State Management
Track strategy state for complex logic:
```python
class TrendFollowingStrategy(IncStrategyBase):
def __init__(self, name: str, params: dict = None):
super().__init__(name, params)
# Strategy state
self.trend_state = "UNKNOWN" # BULLISH, BEARISH, SIDEWAYS
self.position_state = "NONE" # LONG, SHORT, NONE
self.last_signal_time = 0
def _process_aggregated_data(self, timestamp: int, ohlcv: tuple) -> IncStrategySignal:
# Update trend state
self._update_trend_state(ohlcv)
# Generate signals based on trend and position
if self.trend_state == "BULLISH" and self.position_state != "LONG":
self.position_state = "LONG"
return IncStrategySignal.BUY(confidence=0.8)
elif self.trend_state == "BEARISH" and self.position_state != "SHORT":
self.position_state = "SHORT"
return IncStrategySignal.SELL(confidence=0.8)
return IncStrategySignal.HOLD()
```
### 3. Multi-Indicator Strategies
Combine multiple indicators for robust signals:
```python
class MultiIndicatorStrategy(IncStrategyBase):
def __init__(self, name: str, params: dict = None):
super().__init__(name, params)
# Trend indicators
self.supertrend = SupertrendState(period=10, multiplier=3.0)
self.sma_50 = MovingAverageState(period=50)
self.sma_200 = MovingAverageState(period=200)
# Momentum indicators
self.rsi = RSIState(period=14)
# Volatility indicators
self.bb = BollingerBandsState(period=20, std_dev=2.0)
def _process_aggregated_data(self, timestamp: int, ohlcv: tuple) -> IncStrategySignal:
open_price, high, low, close, volume = ohlcv
# Update all indicators
self.supertrend.update_ohlc(high, low, close)
self.sma_50.update(close)
self.sma_200.update(close)
self.rsi.update(close)
self.bb.update(close)
# Wait for all indicators to be ready
if not all([
self.supertrend.is_ready(),
self.sma_50.is_ready(),
self.sma_200.is_ready(),
self.rsi.is_ready(),
self.bb.is_ready()
]):
return IncStrategySignal.HOLD()
# Get indicator values
supertrend_signal = self.supertrend.get_signal()
sma_50 = self.sma_50.get_value()
sma_200 = self.sma_200.get_value()
rsi = self.rsi.get_value()
bb_upper, bb_middle, bb_lower = self.bb.get_bands()
# Multi-condition buy signal
buy_conditions = [
supertrend_signal == 'BUY',
sma_50 > sma_200, # Long-term uptrend
rsi < 70, # Not overbought
close < bb_upper # Not at upper band
]
# Multi-condition sell signal
sell_conditions = [
supertrend_signal == 'SELL',
sma_50 < sma_200, # Long-term downtrend
rsi > 30, # Not oversold
close > bb_lower # Not at lower band
]
if all(buy_conditions):
confidence = sum([1 for c in buy_conditions if c]) / len(buy_conditions)
return IncStrategySignal.BUY(
confidence=confidence,
metadata={
'supertrend': supertrend_signal,
'sma_trend': 'UP' if sma_50 > sma_200 else 'DOWN',
'rsi': rsi,
'bb_position': 'MIDDLE'
}
)
elif all(sell_conditions):
confidence = sum([1 for c in sell_conditions if c]) / len(sell_conditions)
return IncStrategySignal.SELL(
confidence=confidence,
metadata={
'supertrend': supertrend_signal,
'sma_trend': 'DOWN' if sma_50 < sma_200 else 'UP',
'rsi': rsi,
'bb_position': 'MIDDLE'
}
)
return IncStrategySignal.HOLD()
```
## Parameter Management
### Default Parameters
Define default parameters in your strategy:
```python
class MyStrategy(IncStrategyBase):
def __init__(self, name: str, params: dict = None):
# Define defaults
default_params = {
"timeframe": "15min",
"fast_period": 10,
"slow_period": 20,
"rsi_period": 14,
"rsi_overbought": 70,
"rsi_oversold": 30
}
# Merge with provided params
if params:
default_params.update(params)
super().__init__(name, default_params)
# Use parameters
self.fast_sma = MovingAverageState(period=self.params['fast_period'])
self.slow_sma = MovingAverageState(period=self.params['slow_period'])
self.rsi = RSIState(period=self.params['rsi_period'])
```
### Parameter Validation
Add validation for critical parameters:
```python
def __init__(self, name: str, params: dict = None):
super().__init__(name, params)
# Validate parameters
if self.params['fast_period'] >= self.params['slow_period']:
raise ValueError("fast_period must be less than slow_period")
if not (1 <= self.params['rsi_period'] <= 100):
raise ValueError("rsi_period must be between 1 and 100")
```
## Testing Your Strategy
### Unit Testing
```python
import unittest
from IncrementalTrader.strategies.base import IncStrategySignal
class TestMyStrategy(unittest.TestCase):
def setUp(self):
self.strategy = MyCustomStrategy("test", {
"fast_period": 5,
"slow_period": 10
})
def test_initialization(self):
self.assertEqual(self.strategy.name, "test")
self.assertEqual(self.strategy.params['fast_period'], 5)
def test_signal_generation(self):
# Feed test data
test_data = [
(1000, (100, 105, 95, 102, 1000)),
(1001, (102, 108, 100, 106, 1200)),
# ... more test data
]
for timestamp, ohlcv in test_data:
signal = self.strategy.process_data_point(timestamp, ohlcv)
self.assertIsInstance(signal, IncStrategySignal)
```
### Backtesting
```python
from IncrementalTrader import IncBacktester, BacktestConfig
# Test your strategy
config = BacktestConfig(
initial_usd=10000,
start_date="2024-01-01",
end_date="2024-03-31"
)
backtester = IncBacktester()
results = backtester.run_single_strategy(
strategy_class=MyCustomStrategy,
strategy_params={"fast_period": 10, "slow_period": 20},
config=config,
data_file="test_data.csv"
)
print(f"Total Return: {results['performance_metrics']['total_return_pct']:.2f}%")
```
## Best Practices
### 1. Incremental Design
Always design for incremental computation:
```python
# Good: Incremental calculation
class IncrementalSMA:
def __init__(self, period):
self.period = period
self.values = deque(maxlen=period)
self.sum = 0
def update(self, value):
if len(self.values) == self.period:
self.sum -= self.values[0]
self.values.append(value)
self.sum += value
def get_value(self):
return self.sum / len(self.values) if self.values else 0
# Bad: Batch calculation
def calculate_sma(prices, period):
return [sum(prices[i:i+period])/period for i in range(len(prices)-period+1)]
```
### 2. State Management
Keep minimal state and ensure it's always consistent:
```python
def _process_aggregated_data(self, timestamp: int, ohlcv: tuple) -> IncStrategySignal:
# Update all indicators first
self._update_indicators(ohlcv)
# Then update strategy state
self._update_strategy_state()
# Finally generate signal
return self._generate_signal()
```
### 3. Error Handling
Handle edge cases gracefully:
```python
def _process_aggregated_data(self, timestamp: int, ohlcv: tuple) -> IncStrategySignal:
try:
open_price, high, low, close, volume = ohlcv
# Validate data
if not all(isinstance(x, (int, float)) for x in ohlcv):
self.logger.warning(f"Invalid OHLCV data: {ohlcv}")
return IncStrategySignal.HOLD()
if high < low or close < 0:
self.logger.warning(f"Inconsistent price data: {ohlcv}")
return IncStrategySignal.HOLD()
# Your strategy logic here
# ...
except Exception as e:
self.logger.error(f"Error processing data: {e}")
return IncStrategySignal.HOLD()
```
### 4. Logging
Use the built-in logger for debugging:
```python
def _process_aggregated_data(self, timestamp: int, ohlcv: tuple) -> IncStrategySignal:
open_price, high, low, close, volume = ohlcv
# Log important events
if self.sma_fast.get_value() > self.sma_slow.get_value():
self.logger.debug(f"Fast SMA ({self.sma_fast.get_value():.2f}) > Slow SMA ({self.sma_slow.get_value():.2f})")
# Log signal generation
if signal.signal_type != 'HOLD':
self.logger.info(f"Generated {signal.signal_type} signal with confidence {signal.confidence}")
return signal
```
## Example Strategies
### Simple Moving Average Crossover
```python
class SMAStrategy(IncStrategyBase):
def __init__(self, name: str, params: dict = None):
default_params = {
"timeframe": "15min",
"fast_period": 10,
"slow_period": 20
}
if params:
default_params.update(params)
super().__init__(name, default_params)
self.sma_fast = MovingAverageState(period=self.params['fast_period'])
self.sma_slow = MovingAverageState(period=self.params['slow_period'])
self.last_signal = 'HOLD'
def _process_aggregated_data(self, timestamp: int, ohlcv: tuple) -> IncStrategySignal:
_, _, _, close, _ = ohlcv
self.sma_fast.update(close)
self.sma_slow.update(close)
if not (self.sma_fast.is_ready() and self.sma_slow.is_ready()):
return IncStrategySignal.HOLD()
fast = self.sma_fast.get_value()
slow = self.sma_slow.get_value()
if fast > slow and self.last_signal != 'BUY':
self.last_signal = 'BUY'
return IncStrategySignal.BUY(confidence=0.7)
elif fast < slow and self.last_signal != 'SELL':
self.last_signal = 'SELL'
return IncStrategySignal.SELL(confidence=0.7)
return IncStrategySignal.HOLD()
```
### RSI Mean Reversion
```python
class RSIMeanReversionStrategy(IncStrategyBase):
def __init__(self, name: str, params: dict = None):
default_params = {
"timeframe": "15min",
"rsi_period": 14,
"oversold": 30,
"overbought": 70
}
if params:
default_params.update(params)
super().__init__(name, default_params)
self.rsi = RSIState(period=self.params['rsi_period'])
def _process_aggregated_data(self, timestamp: int, ohlcv: tuple) -> IncStrategySignal:
_, _, _, close, _ = ohlcv
self.rsi.update(close)
if not self.rsi.is_ready():
return IncStrategySignal.HOLD()
rsi_value = self.rsi.get_value()
if rsi_value < self.params['oversold']:
return IncStrategySignal.BUY(
confidence=min(1.0, (self.params['oversold'] - rsi_value) / 20),
metadata={'rsi': rsi_value, 'condition': 'oversold'}
)
elif rsi_value > self.params['overbought']:
return IncStrategySignal.SELL(
confidence=min(1.0, (rsi_value - self.params['overbought']) / 20),
metadata={'rsi': rsi_value, 'condition': 'overbought'}
)
return IncStrategySignal.HOLD()
```

# Timeframe Aggregation Usage Guide
## Overview
This guide covers how to use the new timeframe aggregation utilities in the IncrementalTrader framework. The new system provides mathematically correct aggregation with proper timestamp handling to prevent future data leakage.
## Key Features
### ✅ **Fixed Critical Issues**
- **No Future Data Leakage**: Bar timestamps represent END of period
- **Mathematical Correctness**: Results match pandas resampling exactly
- **Trading Industry Standard**: Uses standard bar grouping conventions
- **Proper OHLCV Aggregation**: Correct first/max/min/last/sum rules
### 🚀 **New Capabilities**
- **MinuteDataBuffer**: Efficient real-time data management
- **Flexible Timestamp Modes**: Support for both bar start and end timestamps
- **Memory Bounded**: Automatic buffer size management
- **Performance Optimized**: Fast aggregation for real-time use
## Quick Start
### Basic Usage
```python
from IncrementalTrader.utils.timeframe_utils import aggregate_minute_data_to_timeframe
# Sample minute data
minute_data = [
{
'timestamp': pd.Timestamp('2024-01-01 09:00:00'),
'open': 50000.0, 'high': 50050.0, 'low': 49950.0, 'close': 50025.0, 'volume': 1000
},
{
'timestamp': pd.Timestamp('2024-01-01 09:01:00'),
'open': 50025.0, 'high': 50075.0, 'low': 50000.0, 'close': 50050.0, 'volume': 1200
},
# ... more minute data
]
# Aggregate to 15-minute bars
bars_15m = aggregate_minute_data_to_timeframe(minute_data, "15min")
# Result: bars with END timestamps (no future data leakage)
for bar in bars_15m:
print(f"Bar ending at {bar['timestamp']}: OHLCV = {bar['open']}, {bar['high']}, {bar['low']}, {bar['close']}, {bar['volume']}")
```
### Using MinuteDataBuffer for Real-Time Strategies
```python
from IncrementalTrader.utils.timeframe_utils import MinuteDataBuffer
class MyStrategy(IncStrategyBase):
def __init__(self, name: str = "my_strategy", weight: float = 1.0, params: Optional[Dict] = None):
super().__init__(name, weight, params)
self.timeframe = self.params.get("timeframe", "15min")
self.minute_buffer = MinuteDataBuffer(max_size=1440) # 24 hours
self.last_processed_bar_timestamp = None
def calculate_on_data(self, new_data_point: Dict[str, float], timestamp: pd.Timestamp) -> None:
# Add to buffer
self.minute_buffer.add(timestamp, new_data_point)
# Get latest complete bar
latest_bar = self.minute_buffer.get_latest_complete_bar(self.timeframe)
if latest_bar and latest_bar['timestamp'] != self.last_processed_bar_timestamp:
# Process new complete bar
self.last_processed_bar_timestamp = latest_bar['timestamp']
self._process_complete_bar(latest_bar)
def _process_complete_bar(self, bar: Dict[str, float]) -> None:
# Your strategy logic here
# bar['timestamp'] is the END of the bar period (no future data)
pass
```
## Core Functions
### aggregate_minute_data_to_timeframe()
**Purpose**: Aggregate minute-level OHLCV data to higher timeframes
**Signature**:
```python
def aggregate_minute_data_to_timeframe(
minute_data: List[Dict[str, Union[float, pd.Timestamp]]],
timeframe: str,
timestamp_mode: str = "end"
) -> List[Dict[str, Union[float, pd.Timestamp]]]
```
**Parameters**:
- `minute_data`: List of minute OHLCV dictionaries with 'timestamp' field
- `timeframe`: Target timeframe ("1min", "5min", "15min", "1h", "4h", "1d")
- `timestamp_mode`: "end" (default) for bar end timestamps, "start" for bar start
**Returns**: List of aggregated OHLCV dictionaries with proper timestamps
**Example**:
```python
# Aggregate to 5-minute bars with end timestamps
bars_5m = aggregate_minute_data_to_timeframe(minute_data, "5min", "end")
# Aggregate to 1-hour bars with start timestamps
bars_1h = aggregate_minute_data_to_timeframe(minute_data, "1h", "start")
```
### get_latest_complete_bar()
**Purpose**: Get the latest complete bar for real-time processing
**Signature**:
```python
def get_latest_complete_bar(
minute_data: List[Dict[str, Union[float, pd.Timestamp]]],
timeframe: str,
timestamp_mode: str = "end"
) -> Optional[Dict[str, Union[float, pd.Timestamp]]]
```
**Example**:
```python
# Get latest complete 15-minute bar
latest_15m = get_latest_complete_bar(minute_data, "15min")
if latest_15m:
print(f"Latest complete bar: {latest_15m['timestamp']}")
```
### parse_timeframe_to_minutes()
**Purpose**: Parse timeframe strings to minutes
**Signature**:
```python
def parse_timeframe_to_minutes(timeframe: str) -> int
```
**Supported Formats**:
- Minutes: "1min", "5min", "15min", "30min"
- Hours: "1h", "2h", "4h", "6h", "12h"
- Days: "1d", "7d"
- Weeks: "1w", "2w"
**Example**:
```python
minutes = parse_timeframe_to_minutes("15min") # Returns 15
minutes = parse_timeframe_to_minutes("1h") # Returns 60
minutes = parse_timeframe_to_minutes("1d") # Returns 1440
```
## MinuteDataBuffer Class
### Overview
The `MinuteDataBuffer` class provides efficient buffer management for minute-level data with automatic aggregation capabilities.
### Key Features
- **Memory Bounded**: Configurable maximum size (default: 1440 minutes = 24 hours)
- **Automatic Cleanup**: Old data automatically removed when buffer is full
- **Thread Safe**: Safe for use in multi-threaded environments
- **Efficient Access**: Fast data retrieval and aggregation methods
### Basic Usage
```python
from IncrementalTrader.utils.timeframe_utils import MinuteDataBuffer
# Create buffer for 24 hours of data
buffer = MinuteDataBuffer(max_size=1440)
# Add minute data
buffer.add(timestamp, {
'open': 50000.0,
'high': 50050.0,
'low': 49950.0,
'close': 50025.0,
'volume': 1000
})
# Get aggregated data
bars_15m = buffer.aggregate_to_timeframe("15min", lookback_bars=4)
latest_bar = buffer.get_latest_complete_bar("15min")
# Buffer management
print(f"Buffer size: {buffer.size()}")
print(f"Is full: {buffer.is_full()}")
print(f"Time range: {buffer.get_time_range()}")
```
### Methods
#### add(timestamp, ohlcv_data)
Add new minute data point to the buffer.
```python
buffer.add(pd.Timestamp('2024-01-01 09:00:00'), {
'open': 50000.0, 'high': 50050.0, 'low': 49950.0, 'close': 50025.0, 'volume': 1000
})
```
#### get_data(lookback_minutes=None)
Get data from buffer.
```python
# Get all data
all_data = buffer.get_data()
# Get last 60 minutes
recent_data = buffer.get_data(lookback_minutes=60)
```
#### aggregate_to_timeframe(timeframe, lookback_bars=None, timestamp_mode="end")
Aggregate buffer data to specified timeframe.
```python
# Get last 4 bars of 15-minute data
bars = buffer.aggregate_to_timeframe("15min", lookback_bars=4)
# Get all available 1-hour bars
bars = buffer.aggregate_to_timeframe("1h")
```
#### get_latest_complete_bar(timeframe, timestamp_mode="end")
Get the latest complete bar for the specified timeframe.
```python
latest_bar = buffer.get_latest_complete_bar("15min")
if latest_bar:
print(f"Latest complete bar ends at: {latest_bar['timestamp']}")
```
## Timestamp Modes
### "end" Mode (Default - Recommended)
- **Bar timestamps represent the END of the bar period**
- **Prevents future data leakage**
- **Safe for real-time trading**
```python
# 5-minute bar from 09:00-09:04 is timestamped 09:05
bars = aggregate_minute_data_to_timeframe(data, "5min", "end")
```
### "start" Mode
- **Bar timestamps represent the START of the bar period**
- **Matches some external data sources**
- **Use with caution in real-time systems**
```python
# 5-minute bar from 09:00-09:04 is timestamped 09:00
bars = aggregate_minute_data_to_timeframe(data, "5min", "start")
```
## Best Practices
### 1. Always Use "end" Mode for Real-Time Trading
```python
# ✅ GOOD: Prevents future data leakage
bars = aggregate_minute_data_to_timeframe(data, "15min", "end")
# ❌ RISKY: Could lead to future data leakage
bars = aggregate_minute_data_to_timeframe(data, "15min", "start")
```
### 2. Use MinuteDataBuffer for Strategies
```python
# ✅ GOOD: Efficient memory management
class MyStrategy(IncStrategyBase):
def __init__(self, ...):
self.buffer = MinuteDataBuffer(max_size=1440) # 24 hours
def calculate_on_data(self, data, timestamp):
self.buffer.add(timestamp, data)
latest_bar = self.buffer.get_latest_complete_bar(self.timeframe)
# Process latest_bar...
# ❌ INEFFICIENT: Keeping all data in memory
class BadStrategy(IncStrategyBase):
def __init__(self, ...):
self.all_data = [] # Grows indefinitely
```
### 3. Check for Complete Bars
```python
# ✅ GOOD: Only process complete bars
latest_bar = buffer.get_latest_complete_bar("15min")
if latest_bar and latest_bar['timestamp'] != self.last_processed:
self.process_bar(latest_bar)
self.last_processed = latest_bar['timestamp']
# ❌ BAD: Processing incomplete bars
bars = buffer.aggregate_to_timeframe("15min")
if bars:
self.process_bar(bars[-1]) # Might be incomplete!
```
### 4. Handle Edge Cases
```python
# ✅ GOOD: Robust error handling
try:
bars = aggregate_minute_data_to_timeframe(data, timeframe)
if bars:
# Process bars...
else:
logger.warning("No complete bars available")
except TimeframeError as e:
logger.error(f"Invalid timeframe: {e}")
except ValueError as e:
logger.error(f"Invalid data: {e}")
# ❌ BAD: No error handling
bars = aggregate_minute_data_to_timeframe(data, timeframe)
latest_bar = bars[-1] # Could crash if bars is empty!
```
### 5. Optimize Buffer Size
```python
# ✅ GOOD: Size buffer based on strategy needs
# For 15min strategy needing 20 bars lookback: 20 * 15 = 300 minutes
buffer = MinuteDataBuffer(max_size=300)
# For daily strategy: 24 * 60 = 1440 minutes
buffer = MinuteDataBuffer(max_size=1440)
# ❌ WASTEFUL: Oversized buffer
buffer = MinuteDataBuffer(max_size=10080) # 1 week for 15min strategy
```
## Performance Considerations
### Memory Usage
- **MinuteDataBuffer**: ~1KB per minute of data
- **1440 minutes (24h)**: ~1.4MB memory usage
- **Automatic cleanup**: Old data removed when buffer is full
### Processing Speed
- **Small datasets (< 500 minutes)**: < 5ms aggregation time
- **Large datasets (2000+ minutes)**: < 15ms aggregation time
- **Real-time processing**: < 2ms per minute update
### Optimization Tips
1. **Use appropriate buffer sizes** - don't keep more data than needed
2. **Process complete bars only** - avoid reprocessing incomplete bars
3. **Cache aggregated results** - don't re-aggregate the same data
4. **Use lookback_bars parameter** - limit returned data to what you need
```python
# ✅ OPTIMIZED: Only get what you need
recent_bars = buffer.aggregate_to_timeframe("15min", lookback_bars=20)
# ❌ INEFFICIENT: Getting all data every time
all_bars = buffer.aggregate_to_timeframe("15min")
recent_bars = all_bars[-20:] # Wasteful
```
## Common Patterns
### Pattern 1: Simple Strategy with Buffer
```python
class TrendStrategy(IncStrategyBase):
def __init__(self, name: str = "trend", weight: float = 1.0, params: Optional[Dict] = None):
super().__init__(name, weight, params)
self.timeframe = self.params.get("timeframe", "15min")
self.lookback_period = self.params.get("lookback_period", 20)
# Calculate buffer size: lookback_period * timeframe_minutes
timeframe_minutes = parse_timeframe_to_minutes(self.timeframe)
buffer_size = self.lookback_period * timeframe_minutes
self.buffer = MinuteDataBuffer(max_size=buffer_size)
self.last_processed_timestamp = None
def calculate_on_data(self, new_data_point: Dict[str, float], timestamp: pd.Timestamp) -> None:
# Add to buffer
self.buffer.add(timestamp, new_data_point)
# Get latest complete bar
latest_bar = self.buffer.get_latest_complete_bar(self.timeframe)
if latest_bar and latest_bar['timestamp'] != self.last_processed_timestamp:
# Get historical bars for analysis
historical_bars = self.buffer.aggregate_to_timeframe(
self.timeframe,
lookback_bars=self.lookback_period
)
if len(historical_bars) >= self.lookback_period:
signal = self._analyze_trend(historical_bars)
if signal:
self._generate_signal(signal, latest_bar['timestamp'])
self.last_processed_timestamp = latest_bar['timestamp']
def _analyze_trend(self, bars: List[Dict]) -> Optional[str]:
# Your trend analysis logic here
closes = [bar['close'] for bar in bars]
# ... analysis ...
return "BUY" if trend_up else "SELL" if trend_down else None
```
### Pattern 2: Multi-Timeframe Strategy
```python
class MultiTimeframeStrategy(IncStrategyBase):
def __init__(self, name: str = "multi_tf", weight: float = 1.0, params: Optional[Dict] = None):
super().__init__(name, weight, params)
self.primary_timeframe = self.params.get("primary_timeframe", "15min")
self.secondary_timeframe = self.params.get("secondary_timeframe", "1h")
# Buffer size for the largest timeframe needed
max_timeframe_minutes = max(
parse_timeframe_to_minutes(self.primary_timeframe),
parse_timeframe_to_minutes(self.secondary_timeframe)
)
buffer_size = 50 * max_timeframe_minutes # 50 bars of largest timeframe
self.buffer = MinuteDataBuffer(max_size=buffer_size)
self.last_processed = {
self.primary_timeframe: None,
self.secondary_timeframe: None
}
def calculate_on_data(self, new_data_point: Dict[str, float], timestamp: pd.Timestamp) -> None:
self.buffer.add(timestamp, new_data_point)
# Check both timeframes
for timeframe in [self.primary_timeframe, self.secondary_timeframe]:
latest_bar = self.buffer.get_latest_complete_bar(timeframe)
if latest_bar and latest_bar['timestamp'] != self.last_processed[timeframe]:
self._process_timeframe(timeframe, latest_bar)
self.last_processed[timeframe] = latest_bar['timestamp']
def _process_timeframe(self, timeframe: str, latest_bar: Dict) -> None:
if timeframe == self.primary_timeframe:
# Primary timeframe logic
pass
elif timeframe == self.secondary_timeframe:
# Secondary timeframe logic
pass
```
### Pattern 3: Backtesting with Historical Data
```python
def backtest_strategy(strategy_class, historical_data: List[Dict], params: Dict):
"""Run backtest with historical minute data."""
strategy = strategy_class("backtest", params=params)
signals = []
# Process data chronologically
for data_point in historical_data:
timestamp = data_point['timestamp']
ohlcv = {k: v for k, v in data_point.items() if k != 'timestamp'}
# Process data point
signal = strategy.process_data_point(timestamp, ohlcv)
if signal and signal.signal_type != "HOLD":
signals.append({
'timestamp': timestamp,
'signal_type': signal.signal_type,
'confidence': signal.confidence
})
return signals
# Usage
historical_data = load_historical_data("BTCUSD", "2024-01-01", "2024-01-31")
signals = backtest_strategy(TrendStrategy, historical_data, {"timeframe": "15min"})
```
## Error Handling
### Common Errors and Solutions
#### TimeframeError
```python
try:
bars = aggregate_minute_data_to_timeframe(data, "invalid_timeframe")
except TimeframeError as e:
logger.error(f"Invalid timeframe: {e}")
# Use default timeframe
bars = aggregate_minute_data_to_timeframe(data, "15min")
```
#### ValueError (Invalid Data)
```python
try:
buffer.add(timestamp, ohlcv_data)
except ValueError as e:
logger.error(f"Invalid data: {e}")
# Skip this data point
continue
```
#### Empty Data
```python
bars = aggregate_minute_data_to_timeframe(minute_data, "15min")
if not bars:
logger.warning("No complete bars available")
return
latest_bar = get_latest_complete_bar(minute_data, "15min")
if latest_bar is None:
logger.warning("No complete bar available")
return
```
## Migration from Old System
### Before (Old TimeframeAggregator)
```python
# Old approach - potential future data leakage
class OldStrategy(IncStrategyBase):
def __init__(self, ...):
self.aggregator = TimeframeAggregator(timeframe="15min")
def calculate_on_data(self, data, timestamp):
# Potential issues:
# - Bar timestamps might represent start (future data leakage)
# - Inconsistent aggregation logic
# - Memory not bounded
pass
```
### After (New Utilities)
```python
# New approach - safe and efficient
class NewStrategy(IncStrategyBase):
def __init__(self, ...):
self.buffer = MinuteDataBuffer(max_size=1440)
self.timeframe = "15min"
self.last_processed = None
def calculate_on_data(self, data, timestamp):
self.buffer.add(timestamp, data)
latest_bar = self.buffer.get_latest_complete_bar(self.timeframe)
if latest_bar and latest_bar['timestamp'] != self.last_processed:
# Safe: bar timestamp is END of period (no future data)
# Efficient: bounded memory usage
# Correct: matches pandas resampling
self.process_bar(latest_bar)
self.last_processed = latest_bar['timestamp']
```
### Migration Checklist
- [ ] Replace `TimeframeAggregator` with `MinuteDataBuffer`
- [ ] Update timestamp handling to use "end" mode
- [ ] Add checks for complete bars only
- [ ] Set appropriate buffer sizes
- [ ] Update error handling
- [ ] Test with historical data
- [ ] Verify no future data leakage
## Troubleshooting
### Issue: No bars returned
**Cause**: Not enough data for complete bars
**Solution**: Check data length vs timeframe requirements
```python
timeframe_minutes = parse_timeframe_to_minutes("15min") # 15
if len(minute_data) < timeframe_minutes:
logger.warning(f"Need at least {timeframe_minutes} minutes for {timeframe} bars")
```
### Issue: Memory usage growing
**Cause**: Buffer size too large or not using buffer
**Solution**: Optimize buffer size
```python
# Calculate optimal buffer size
lookback_bars = 20
timeframe_minutes = parse_timeframe_to_minutes("15min")
optimal_size = lookback_bars * timeframe_minutes # 300 minutes
buffer = MinuteDataBuffer(max_size=optimal_size)
```
### Issue: Signals generated too frequently
**Cause**: Processing incomplete bars
**Solution**: Only process complete bars
```python
# ✅ CORRECT: Only process new complete bars
if latest_bar and latest_bar['timestamp'] != self.last_processed:
self.process_bar(latest_bar)
self.last_processed = latest_bar['timestamp']
# ❌ WRONG: Processing every minute
self.process_bar(latest_bar) # Processes same bar multiple times
```
### Issue: Inconsistent results
**Cause**: Using "start" mode or wrong pandas comparison
**Solution**: Use "end" mode and trading standard comparison
```python
# ✅ CORRECT: Trading standard with end timestamps
bars = aggregate_minute_data_to_timeframe(data, "15min", "end")
# ❌ INCONSISTENT: Start mode can cause confusion
bars = aggregate_minute_data_to_timeframe(data, "15min", "start")
```
---
## Summary
The new timeframe aggregation system provides:
- **✅ Mathematical Correctness**: Matches pandas resampling exactly
- **✅ No Future Data Leakage**: Bar end timestamps prevent future data usage
- **✅ Trading Industry Standard**: Compatible with major trading platforms
- **✅ Memory Efficient**: Bounded buffer management
- **✅ Performance Optimized**: Fast real-time processing
- **✅ Easy to Use**: Simple, intuitive API
Use this guide to implement robust, efficient timeframe aggregation in your trading strategies!

Abstract base class for all incremental trading strategies.
This class defines the interface that all incremental strategies must implement:
- get_minimum_buffer_size(): Specify minimum data requirements
- process_data_point(): Process new data points incrementally
- supports_incremental_calculation(): Whether strategy supports incremental mode
- get_entry_signal(): Generate entry signals
- get_exit_signal(): Generate exit signals
The incremental approach allows strategies to:
- Process new data points without full recalculation
- Maintain bounded memory usage regardless of data history length
- Provide real-time performance with minimal latency
- Support both initialization and incremental modes
- Accept minute-level data and internally aggregate to any timeframe
New Features:
- Built-in TimeframeAggregator for minute-level data processing
- update_minute_data() method for real-time trading systems
- Automatic timeframe detection and aggregation
- Backward compatibility with existing update() methods

identical results to the batch implementation after the warm-up period.
Key Features:
- Accepts minute-level data input for real-time compatibility
- Internal timeframe aggregation (1min, 5min, 15min, 1h, etc.)
- Incremental Bollinger Bands calculation
- Incremental RSI calculation with Wilder's smoothing
- Market regime detection (trending vs sideways)
- Real-time signal generation

Incremental BBRS (Bollinger Bands + RSI) strategy implementation.
This strategy combines Bollinger Bands and RSI indicators to detect market
conditions and generate trading signals. It adapts its behavior based on
market regime detection (trending vs sideways markets).
The strategy uses different Bollinger Band multipliers and RSI thresholds
for different market regimes:
- Trending markets: Breakout strategy with higher BB multiplier
- Sideways markets: Mean reversion strategy with lower BB multiplier
Parameters:
timeframe (str): Primary timeframe for analysis (default: "1h")
bb_period (int): Bollinger Bands period (default: 20)
rsi_period (int): RSI period (default: 14)
bb_width_threshold (float): BB width threshold for regime detection (default: 0.05)
trending_bb_multiplier (float): BB multiplier for trending markets (default: 2.5)
sideways_bb_multiplier (float): BB multiplier for sideways markets (default: 1.8)
trending_rsi_thresholds (list): RSI thresholds for trending markets (default: [30, 70])

Incremental MetaTrend Strategy
This module implements an incremental version of the DefaultStrategy that processes
real-time data efficiently while producing identical meta-trend signals to the
original batch-processing implementation.
The strategy uses 3 Supertrend indicators with parameters:
- Supertrend 1: period=12, multiplier=3.0
- Supertrend 2: period=10, multiplier=1.0
- Supertrend 3: period=11, multiplier=2.0
Meta-trend calculation:
- Meta-trend = 1 when all 3 Supertrends agree on uptrend
- Meta-trend = -1 when all 3 Supertrends agree on downtrend
- Meta-trend = 0 when Supertrends disagree (neutral)
Signal generation:
- Entry: meta-trend changes from != 1 to == 1
- Exit: meta-trend changes from != -1 to == -1
Stop-loss handling is delegated to the trader layer.

- Supports bar end timestamps (default) to prevent future data leakage
- Proper OHLCV aggregation rules (first/max/min/last/sum)
- MinuteDataBuffer for efficient real-time data management
- Comprehensive error handling and validation
Critical Fixes:
1. Bar timestamps represent END of period (no future data leakage)

Helper class for managing minute data buffers in real-time strategies.
This class provides efficient buffer management for minute-level data with
automatic aggregation capabilities. It's designed for use in incremental

Features:
- Automatic buffer size management with configurable limits
- Efficient data access and aggregation methods
- Memory-bounded operation (doesn't grow indefinitely)
- Thread-safe operations for real-time use
- Comprehensive validation and error handling
Example:
>>> buffer = MinuteDataBuffer(max_size=1440) # 24 hours

# Analysis Module
This document provides an overview of the `Analysis` module and its components, which are typically used for technical analysis of financial market data.
## Modules
The `Analysis` module includes classes for calculating common technical indicators:
- **Relative Strength Index (RSI)**: Implemented in `cycles/Analysis/rsi.py`.
- **Bollinger Bands**: Implemented in `cycles/Analysis/boillinger_band.py`.
- Note: Trading strategies are detailed in `strategies.md`.
## Class: `RSI`
Found in `cycles/Analysis/rsi.py`.
Calculates the Relative Strength Index.
### Mathematical Model
The standard RSI calculation typically involves Wilder's smoothing for average gains and losses.
1. **Price Change (Delta)**: Difference between consecutive closing prices.
2. **Gain and Loss**: Separate positive (gain) and negative (loss, expressed as positive) price changes.
3. **Average Gain (AvgU)** and **Average Loss (AvgD)**: Smoothed averages of gains and losses over the RSI period. Wilder's smoothing is a specific type of exponential moving average (EMA):
- Initial AvgU/AvgD: Simple Moving Average (SMA) over the first `period` values.
- Subsequent AvgU: `(Previous AvgU * (period - 1) + Current Gain) / period`
- Subsequent AvgD: `(Previous AvgD * (period - 1) + Current Loss) / period`
4. **Relative Strength (RS)**:
$$
RS = \\frac{\\text{AvgU}}{\\text{AvgD}}
$$
5. **RSI**:
$$
RSI = 100 - \\frac{100}{1 + RS}
$$
Special conditions:
- If AvgD is 0: RSI is 100 if AvgU > 0, or 50 if AvgU is also 0 (neutral).
### `__init__(self, config: dict)`
- **Description**: Initializes the RSI calculator.
- **Parameters**:\n - `config` (dict): Configuration dictionary. Must contain an `'rsi_period'` key with a positive integer value (e.g., `{'rsi_period': 14}`).
### `calculate(self, data_df: pd.DataFrame, price_column: str = 'close') -> pd.DataFrame`
- **Description**: Calculates the RSI (using Wilder's smoothing by default) and adds it as an 'RSI' column to the input DataFrame. This method utilizes `calculate_custom_rsi` internally with `smoothing='EMA'`.
- **Parameters**:\n - `data_df` (pd.DataFrame): DataFrame with historical price data. Must contain the `price_column`.\n - `price_column` (str, optional): The name of the column containing price data. Defaults to 'close'.
- **Returns**: `pd.DataFrame` - A copy of the input DataFrame with an added 'RSI' column. If data length is insufficient for the period, the 'RSI' column will contain `np.nan`.
### `calculate_custom_rsi(price_series: pd.Series, window: int = 14, smoothing: str = 'SMA') -> pd.Series` (Static Method)
- **Description**: Calculates RSI with a specified window and smoothing method (SMA or EMA). This is the core calculation engine.
- **Parameters**:
- `price_series` (pd.Series): Series of prices.
- `window` (int, optional): The period for RSI calculation. Defaults to 14. Must be a positive integer.
- `smoothing` (str, optional): Smoothing method, can be 'SMA' (Simple Moving Average) or 'EMA' (Exponential Moving Average, specifically Wilder's smoothing when `alpha = 1/window`). Defaults to 'SMA'.
- **Returns**: `pd.Series` - Series containing the RSI values. Returns a series of NaNs if data length is insufficient.
## Class: `BollingerBands`
Found in `cycles/Analysis/boillinger_band.py`.
Calculates Bollinger Bands.
### Mathematical Model
1. **Middle Band**: Simple Moving Average (SMA) over `period`.
$$
\\text{Middle Band} = \\text{SMA}(\\text{price}, \\text{period})
$$
2. **Standard Deviation (σ)**: Standard deviation of price over `period`.
3. **Upper Band**: Middle Band + `num_std` × σ
$$
\\text{Upper Band} = \\text{Middle Band} + \\text{num_std} \\times \\sigma_{\\text{period}}
$$
4. **Lower Band**: Middle Band `num_std` × σ
$$
\\text{Lower Band} = \\text{Middle Band} - \\text{num_std} \\times \\sigma_{\\text{period}}
$$
For the adaptive calculation in the `calculate` method (when `squeeze=False`):
- **BBWidth**: `(Reference Upper Band - Reference Lower Band) / SMA`, where reference bands are typically calculated using a 2.0 standard deviation multiplier.
- **MarketRegime**: Determined by comparing `BBWidth` to a threshold from the configuration. `1` for sideways, `0` for trending.
- The `num_std` used for the final Upper and Lower Bands then varies based on this `MarketRegime` and the `bb_std_dev_multiplier` values for "trending" and "sideways" markets from the configuration, applied row-wise.
### `__init__(self, config: dict)`
- **Description**: Initializes the BollingerBands calculator.
- **Parameters**:\n - `config` (dict): Configuration dictionary. It must contain:
- `'bb_period'` (int): Positive integer for the moving average and standard deviation period.
- `'trending'` (dict): Containing `'bb_std_dev_multiplier'` (float, positive) for trending markets.
- `'sideways'` (dict): Containing `'bb_std_dev_multiplier'` (float, positive) for sideways markets.
- `'bb_width'` (float): Positive float threshold for determining market regime.
### `calculate(self, data_df: pd.DataFrame, price_column: str = 'close', squeeze: bool = False) -> pd.DataFrame`
- **Description**: Calculates Bollinger Bands and adds relevant columns to the DataFrame.
- If `squeeze` is `False` (default): Calculates adaptive Bollinger Bands. It determines the market regime (trending/sideways) based on `BBWidth` and applies different standard deviation multipliers (from the `config`) on a row-by-row basis. Adds 'SMA', 'UpperBand', 'LowerBand', 'BBWidth', and 'MarketRegime' columns.
- If `squeeze` is `True`: Calculates simpler Bollinger Bands with a fixed window of 14 and a standard deviation multiplier of 1.5 by calling `calculate_custom_bands`. Adds 'SMA', 'UpperBand', 'LowerBand' columns; 'BBWidth' and 'MarketRegime' will be `NaN`.
- **Parameters**:\n - `data_df` (pd.DataFrame): DataFrame with price data. Must include the `price_column`.\n - `price_column` (str, optional): The name of the column containing the price data. Defaults to 'close'.\n - `squeeze` (bool, optional): If `True`, calculates bands with fixed parameters (window 14, std 1.5). Defaults to `False`.
- **Returns**: `pd.DataFrame` - A copy of the original DataFrame with added Bollinger Band related columns.
### `calculate_custom_bands(price_series: pd.Series, window: int = 20, num_std: float = 2.0, min_periods: int = None) -> tuple[pd.Series, pd.Series, pd.Series]` (Static Method)
- **Description**: Calculates Bollinger Bands with a specified window, standard deviation multiplier, and minimum periods.
- **Parameters**:
- `price_series` (pd.Series): Series of prices.
- `window` (int, optional): The period for the moving average and standard deviation. Defaults to 20.
- `num_std` (float, optional): The number of standard deviations for the upper and lower bands. Defaults to 2.0.
- `min_periods` (int, optional): Minimum number of observations in window required to have a value. Defaults to `window` if `None`.
- **Returns**: `tuple[pd.Series, pd.Series, pd.Series]` - A tuple containing the Upper band, SMA, and Lower band series.

# Strategies Documentation
## Overview
The Cycles framework implements advanced trading strategies with sophisticated timeframe management, signal processing, and multi-strategy combination capabilities. Each strategy can operate on its preferred timeframes while maintaining precise execution control.
## Architecture
### Strategy System Components
1. **StrategyBase**: Abstract base class with timeframe management
2. **Individual Strategies**: DefaultStrategy, BBRSStrategy implementations
3. **StrategyManager**: Multi-strategy orchestration and signal combination
4. **Timeframe System**: Automatic data resampling and signal mapping
### New Timeframe Management
Each strategy now controls its own timeframe requirements:
```python
class MyStrategy(StrategyBase):
def get_timeframes(self):
return ["15min", "1h"] # Strategy specifies needed timeframes
def initialize(self, backtester):
# Framework automatically resamples data
self._resample_data(backtester.original_df)
# Access resampled data
data_15m = self.get_data_for_timeframe("15min")
data_1h = self.get_data_for_timeframe("1h")
```
## Available Strategies
### 1. Default Strategy (Meta-Trend Analysis)
**Purpose**: Meta-trend analysis using multiple Supertrend indicators
**Timeframe Behavior**:
- **Configurable Primary Timeframe**: Set via `params["timeframe"]` (default: "15min")
- **1-Minute Precision**: Always includes 1min data for precise stop-loss execution
- **Example Timeframes**: `["15min", "1min"]` or `["5min", "1min"]`
**Configuration**:
```json
{
"name": "default",
"weight": 1.0,
"params": {
"timeframe": "15min", // Configurable: "5min", "15min", "1h", etc.
"stop_loss_pct": 0.03 // Stop loss percentage
}
}
```
**Algorithm**:
1. Calculate 3 Supertrend indicators with different parameters on primary timeframe
2. Determine meta-trend: all three must agree for directional signal
3. **Entry**: Meta-trend changes from != 1 to == 1 (all trends align upward)
4. **Exit**: Meta-trend changes to -1 (trend reversal) or stop-loss triggered
5. **Stop-Loss**: 1-minute precision using percentage-based threshold
**Strengths**:
- Robust trend following with multiple confirmations
- Configurable for different market timeframes
- Precise risk management
- Low false signals in trending markets
**Best Use Cases**:
- Medium to long-term trend following
- Markets with clear directional movements
- Risk-conscious trading with defined exits
### 2. BBRS Strategy (Bollinger Bands + RSI)
**Purpose**: Market regime-adaptive strategy combining Bollinger Bands and RSI
**Timeframe Behavior**:
- **1-Minute Input**: Strategy receives 1-minute data
- **Internal Resampling**: Underlying Strategy class handles resampling to 15min/1h
- **No Double-Resampling**: Avoids conflicts with existing resampling logic
- **Signal Mapping**: Results mapped back to 1-minute resolution
**Configuration**:
```json
{
"name": "bbrs",
"weight": 1.0,
"params": {
"bb_width": 0.05, // Bollinger Band width threshold
"bb_period": 20, // Bollinger Band period
"rsi_period": 14, // RSI calculation period
"trending_rsi_threshold": [30, 70], // RSI thresholds for trending market
"trending_bb_multiplier": 2.5, // BB multiplier for trending market
"sideways_rsi_threshold": [40, 60], // RSI thresholds for sideways market
"sideways_bb_multiplier": 1.8, // BB multiplier for sideways market
"strategy_name": "MarketRegimeStrategy", // Implementation variant
"SqueezeStrategy": true, // Enable squeeze detection
"stop_loss_pct": 0.05 // Stop loss percentage
}
}
```
**Algorithm**:
**MarketRegimeStrategy** (Primary Implementation):
1. **Market Regime Detection**: Determines if market is trending or sideways
2. **Adaptive Parameters**: Adjusts BB/RSI thresholds based on market regime
3. **Trending Market Entry**: Price < Lower Band RSI < 50 Volume Spike
4. **Sideways Market Entry**: Price ≤ Lower Band ∧ RSI ≤ 40
5. **Exit Conditions**: Opposite band touch, RSI reversal, or stop-loss
6. **Volume Confirmation**: Requires 1.5× average volume for trending signals
**CryptoTradingStrategy** (Alternative Implementation):
1. **Multi-Timeframe Analysis**: Combines 15-minute and 1-hour Bollinger Bands
2. **Entry**: Price ≤ both 15m & 1h lower bands + RSI < 35 + Volume surge
3. **Exit**: 2:1 risk-reward ratio with ATR-based stops
4. **Adaptive Volatility**: Uses ATR for dynamic stop-loss/take-profit
**Strengths**:
- Adapts to different market regimes
- Multiple timeframe confirmation (internal)
- Volume analysis for signal quality
- Sophisticated entry/exit conditions
**Best Use Cases**:
- Volatile cryptocurrency markets
- Markets with alternating trending/sideways periods
- Short to medium-term trading
## Strategy Combination
### Multi-Strategy Architecture
The StrategyManager allows combining multiple strategies with configurable rules:
```json
{
"strategies": [
{
"name": "default",
"weight": 0.6,
"params": {"timeframe": "15min"}
},
{
"name": "bbrs",
"weight": 0.4,
"params": {"strategy_name": "MarketRegimeStrategy"}
}
],
"combination_rules": {
"entry": "weighted_consensus",
"exit": "any",
"min_confidence": 0.6
}
}
```
### Signal Combination Methods
**Entry Combinations**:
- **`any`**: Enter if ANY strategy signals entry
- **`all`**: Enter only if ALL strategies signal entry
- **`majority`**: Enter if majority of strategies signal entry
- **`weighted_consensus`**: Enter based on weighted confidence average
**Exit Combinations**:
- **`any`**: Exit if ANY strategy signals exit (recommended for risk management)
- **`all`**: Exit only if ALL strategies agree
- **`priority`**: Prioritized exit (STOP_LOSS > SELL_SIGNAL > others)
## Performance Characteristics
### Default Strategy Performance
**Strengths**:
- **Trend Accuracy**: High accuracy in strong trending markets
- **Risk Management**: Defined stop-losses with 1-minute precision
- **Low Noise**: Multiple Supertrend confirmation reduces false signals
- **Adaptable**: Works across different timeframes
**Weaknesses**:
- **Sideways Markets**: May generate false signals in ranging markets
- **Lag**: Multiple confirmations can delay entry/exit signals
- **Whipsaws**: Vulnerable to rapid trend reversals
**Optimal Conditions**:
- Clear trending markets
- Medium to low volatility trending
- Sufficient data history for Supertrend calculation
### BBRS Strategy Performance
**Strengths**:
- **Market Adaptation**: Automatically adjusts to market regime
- **Volume Confirmation**: Reduces false signals with volume analysis
- **Multi-Timeframe**: Internal analysis across multiple timeframes
- **Volatility Handling**: Designed for cryptocurrency volatility
**Weaknesses**:
- **Complexity**: More parameters to optimize
- **Market Noise**: Can be sensitive to short-term noise
- **Volume Dependency**: Requires reliable volume data
**Optimal Conditions**:
- High-volume cryptocurrency markets
- Markets with clear regime shifts
- Sufficient data for regime detection
## Usage Examples
### Single Strategy Backtests
```bash
# Default strategy on 15-minute timeframe
uv run .\main.py .\configs\config_default.json
# Default strategy on 5-minute timeframe
uv run .\main.py .\configs\config_default_5min.json
# BBRS strategy with market regime detection
uv run .\main.py .\configs\config_bbrs.json
```
### Multi-Strategy Backtests
```bash
# Combined strategies with weighted consensus
uv run .\main.py .\configs\config_combined.json
```
### Custom Configurations
**Aggressive Default Strategy**:
```json
{
"name": "default",
"params": {
"timeframe": "5min", // Faster signals
"stop_loss_pct": 0.02 // Tighter stop-loss
}
}
```
**Conservative BBRS Strategy**:
```json
{
"name": "bbrs",
"params": {
"bb_width": 0.03, // Tighter BB width
"stop_loss_pct": 0.07, // Wider stop-loss
"SqueezeStrategy": false // Disable squeeze for simplicity
}
}
```
## Development Guidelines
### Creating New Strategies
1. **Inherit from StrategyBase**:
```python
from cycles.strategies.base import StrategyBase, StrategySignal
class NewStrategy(StrategyBase):
def __init__(self, weight=1.0, params=None):
super().__init__("new_strategy", weight, params)
```
2. **Specify Timeframes**:
```python
def get_timeframes(self):
return ["1h"] # Specify required timeframes
```
3. **Implement Core Methods**:
```python
def initialize(self, backtester):
self._resample_data(backtester.original_df)
# Calculate indicators...
self.initialized = True
def get_entry_signal(self, backtester, df_index):
# Entry logic...
return StrategySignal("ENTRY", confidence=0.8)
def get_exit_signal(self, backtester, df_index):
# Exit logic...
return StrategySignal("EXIT", confidence=1.0)
```
4. **Register Strategy**:
```python
# In StrategyManager._load_strategies()
elif name == "new_strategy":
strategies.append(NewStrategy(weight, params))
```
### Timeframe Best Practices
1. **Minimize Timeframe Requirements**:
```python
def get_timeframes(self):
return ["15min"] # Only what's needed
```
2. **Include 1min for Stop-Loss**:
```python
def get_timeframes(self):
primary_tf = self.params.get("timeframe", "15min")
timeframes = [primary_tf]
if "1min" not in timeframes:
timeframes.append("1min")
return timeframes
```
3. **Handle Multi-Timeframe Synchronization**:
```python
def get_entry_signal(self, backtester, df_index):
# Get current timestamp from primary timeframe
primary_data = self.get_primary_timeframe_data()
current_time = primary_data.index[df_index]
# Map to other timeframes
hourly_data = self.get_data_for_timeframe("1h")
h1_idx = hourly_data.index.get_indexer([current_time], method='ffill')[0]
```
## Testing and Validation
### Strategy Testing Workflow
1. **Individual Strategy Testing**:
- Test each strategy independently
- Validate on different timeframes
- Check edge cases and data sufficiency
2. **Multi-Strategy Testing**:
- Test strategy combinations
- Validate combination rules
- Monitor for signal conflicts
3. **Timeframe Validation**:
- Ensure consistent behavior across timeframes
- Validate data alignment
- Check memory usage with large datasets
### Performance Monitoring
```python
# Get strategy summary
summary = strategy_manager.get_strategy_summary()
print(f"Strategies: {[s['name'] for s in summary['strategies']]}")
print(f"Timeframes: {summary['all_timeframes']}")
# Monitor individual strategy performance
for strategy in strategy_manager.strategies:
print(f"{strategy.name}: {strategy.get_timeframes()}")
```
## Advanced Topics
### Multi-Timeframe Strategy Development
For strategies requiring multiple timeframes:
```python
class MultiTimeframeStrategy(StrategyBase):
def get_timeframes(self):
return ["5min", "15min", "1h"]
def get_entry_signal(self, backtester, df_index):
# Analyze multiple timeframes
data_5m = self.get_data_for_timeframe("5min")
data_15m = self.get_data_for_timeframe("15min")
data_1h = self.get_data_for_timeframe("1h")
# Synchronize across timeframes
current_time = data_5m.index[df_index]
idx_15m = data_15m.index.get_indexer([current_time], method='ffill')[0]
idx_1h = data_1h.index.get_indexer([current_time], method='ffill')[0]
# Multi-timeframe logic
short_signal = self._analyze_5min(data_5m, df_index)
medium_signal = self._analyze_15min(data_15m, idx_15m)
long_signal = self._analyze_1h(data_1h, idx_1h)
# Combine signals with appropriate confidence
if short_signal and medium_signal and long_signal:
return StrategySignal("ENTRY", confidence=0.9)
elif short_signal and medium_signal:
return StrategySignal("ENTRY", confidence=0.7)
else:
return StrategySignal("HOLD", confidence=0.0)
```
### Strategy Optimization
1. **Parameter Optimization**: Systematic testing of strategy parameters
2. **Timeframe Optimization**: Finding optimal timeframes for each strategy
3. **Combination Optimization**: Optimizing weights and combination rules
4. **Market Regime Adaptation**: Adapting strategies to different market conditions

# Strategy Manager Documentation
## Overview
The Strategy Manager is a sophisticated orchestration system that enables the combination of multiple trading strategies with configurable signal aggregation rules. It supports multi-timeframe analysis, weighted consensus voting, and flexible signal combination methods.
## Architecture
### Core Components
1. **StrategyBase**: Abstract base class defining the strategy interface
2. **StrategySignal**: Encapsulates trading signals with confidence levels
3. **StrategyManager**: Orchestrates multiple strategies and combines signals
4. **Strategy Implementations**: DefaultStrategy, BBRSStrategy, etc.
### New Timeframe System
The framework now supports strategy-level timeframe management:
- **Strategy-Controlled Timeframes**: Each strategy specifies its required timeframes
- **Automatic Data Resampling**: Framework automatically resamples 1-minute data to strategy needs
- **Multi-Timeframe Support**: Strategies can use multiple timeframes simultaneously
- **Precision Stop-Loss**: All strategies maintain 1-minute data for precise execution
```python
class MyStrategy(StrategyBase):
def get_timeframes(self):
return ["15min", "1h"] # Strategy needs both timeframes
def initialize(self, backtester):
# Access resampled data
data_15m = self.get_data_for_timeframe("15min")
data_1h = self.get_data_for_timeframe("1h")
# Setup indicators...
```
## Strategy Interface
### StrategyBase Class
All strategies must inherit from `StrategyBase` and implement:
```python
from cycles.strategies.base import StrategyBase, StrategySignal
class MyStrategy(StrategyBase):
def get_timeframes(self) -> List[str]:
"""Specify required timeframes"""
return ["15min"]
def initialize(self, backtester) -> None:
"""Setup strategy with data"""
self._resample_data(backtester.original_df)
# Calculate indicators...
self.initialized = True
def get_entry_signal(self, backtester, df_index: int) -> StrategySignal:
"""Generate entry signals"""
if condition_met:
return StrategySignal("ENTRY", confidence=0.8)
return StrategySignal("HOLD", confidence=0.0)
def get_exit_signal(self, backtester, df_index: int) -> StrategySignal:
"""Generate exit signals"""
if exit_condition:
return StrategySignal("EXIT", confidence=1.0,
metadata={"type": "SELL_SIGNAL"})
return StrategySignal("HOLD", confidence=0.0)
```
### StrategySignal Class
Encapsulates trading signals with metadata:
```python
# Entry signal with high confidence
entry_signal = StrategySignal("ENTRY", confidence=0.9)
# Exit signal with specific price
exit_signal = StrategySignal("EXIT", confidence=1.0, price=50000,
metadata={"type": "STOP_LOSS"})
# Hold signal
hold_signal = StrategySignal("HOLD", confidence=0.0)
```
## Available Strategies
### 1. Default Strategy
Meta-trend analysis using multiple Supertrend indicators.
**Features:**
- Uses 3 Supertrend indicators with different parameters
- Configurable timeframe (default: 15min)
- Entry when all trends align upward
- Exit on trend reversal or stop-loss
**Configuration:**
```json
{
"name": "default",
"weight": 1.0,
"params": {
"timeframe": "15min",
"stop_loss_pct": 0.03
}
}
```
**Timeframes:**
- Primary: Configurable (default 15min)
- Stop-loss: Always includes 1min for precision
### 2. BBRS Strategy
Bollinger Bands + RSI with market regime detection.
**Features:**
- Market regime detection (trending vs sideways)
- Adaptive parameters based on market conditions
- Volume analysis and confirmation
- Multi-timeframe internal analysis (1min → 15min/1h)
**Configuration:**
```json
{
"name": "bbrs",
"weight": 1.0,
"params": {
"bb_width": 0.05,
"bb_period": 20,
"rsi_period": 14,
"strategy_name": "MarketRegimeStrategy",
"stop_loss_pct": 0.05
}
}
```
**Timeframes:**
- Input: 1min (Strategy class handles internal resampling)
- Internal: 15min, 1h (handled by underlying Strategy class)
- Output: Mapped back to 1min for backtesting
## Signal Combination
### Entry Signal Combination
```python
combination_rules = {
"entry": "weighted_consensus", # or "any", "all", "majority"
"min_confidence": 0.6
}
```
**Methods:**
- **`any`**: Enter if ANY strategy signals entry
- **`all`**: Enter only if ALL strategies signal entry
- **`majority`**: Enter if majority of strategies signal entry
- **`weighted_consensus`**: Enter based on weighted average confidence
### Exit Signal Combination
```python
combination_rules = {
"exit": "priority" # or "any", "all"
}
```
**Methods:**
- **`any`**: Exit if ANY strategy signals exit (recommended for risk management)
- **`all`**: Exit only if ALL strategies agree
- **`priority`**: Prioritized exit (STOP_LOSS > SELL_SIGNAL > others)
## Configuration
### Basic Strategy Manager Setup
```json
{
"strategies": [
{
"name": "default",
"weight": 0.6,
"params": {
"timeframe": "15min",
"stop_loss_pct": 0.03
}
},
{
"name": "bbrs",
"weight": 0.4,
"params": {
"bb_width": 0.05,
"strategy_name": "MarketRegimeStrategy"
}
}
],
"combination_rules": {
"entry": "weighted_consensus",
"exit": "any",
"min_confidence": 0.5
}
}
```
### Timeframe Examples
**Single Timeframe Strategy:**
```json
{
"name": "default",
"params": {
"timeframe": "5min" # Strategy works on 5-minute data
}
}
```
**Multi-Timeframe Strategy (Future Enhancement):**
```json
{
"name": "multi_tf_strategy",
"params": {
"timeframes": ["5min", "15min", "1h"], # Multiple timeframes
"primary_timeframe": "15min"
}
}
```
## Usage Examples
### Create Strategy Manager
```python
from cycles.strategies import create_strategy_manager
config = {
"strategies": [
{"name": "default", "weight": 1.0, "params": {"timeframe": "15min"}}
],
"combination_rules": {
"entry": "any",
"exit": "any"
}
}
strategy_manager = create_strategy_manager(config)
```
### Initialize and Use
```python
# Initialize with backtester
strategy_manager.initialize(backtester)
# Get signals during backtesting
entry_signal = strategy_manager.get_entry_signal(backtester, df_index)
exit_signal, exit_price = strategy_manager.get_exit_signal(backtester, df_index)
# Get strategy summary
summary = strategy_manager.get_strategy_summary()
print(f"Loaded strategies: {[s['name'] for s in summary['strategies']]}")
print(f"All timeframes: {summary['all_timeframes']}")
```
## Extending the System
### Adding New Strategies
1. **Create Strategy Class:**
```python
class NewStrategy(StrategyBase):
def get_timeframes(self):
return ["1h"] # Specify required timeframes
def initialize(self, backtester):
self._resample_data(backtester.original_df)
# Setup indicators...
self.initialized = True
def get_entry_signal(self, backtester, df_index):
# Implement entry logic
pass
def get_exit_signal(self, backtester, df_index):
# Implement exit logic
pass
```
2. **Register in StrategyManager:**
```python
# In StrategyManager._load_strategies()
elif name == "new_strategy":
strategies.append(NewStrategy(weight, params))
```
### Multi-Timeframe Strategy Development
For strategies requiring multiple timeframes:
```python
class MultiTimeframeStrategy(StrategyBase):
def get_timeframes(self):
return ["5min", "15min", "1h"]
def initialize(self, backtester):
self._resample_data(backtester.original_df)
# Access different timeframes
data_5m = self.get_data_for_timeframe("5min")
data_15m = self.get_data_for_timeframe("15min")
data_1h = self.get_data_for_timeframe("1h")
# Calculate indicators on each timeframe
# ...
def _calculate_signal_confidence(self, backtester, df_index):
# Analyze multiple timeframes for confidence
primary_signal = self._get_primary_signal(df_index)
confirmation = self._get_timeframe_confirmation(df_index)
return primary_signal * confirmation
```
## Performance Considerations
### Timeframe Management
- **Efficient Resampling**: Each strategy resamples data once during initialization
- **Memory Usage**: Only required timeframes are kept in memory
- **Signal Mapping**: Efficient mapping between timeframes using pandas reindex
### Strategy Combination
- **Lazy Evaluation**: Signals calculated only when needed

# Timeframe System Documentation
## Overview
The Cycles framework features a sophisticated timeframe management system that allows strategies to operate on their preferred timeframes while maintaining precise execution control. This system supports both single-timeframe and multi-timeframe strategies with automatic data resampling and intelligent signal mapping.
## Architecture
### Core Concepts
1. **Strategy-Controlled Timeframes**: Each strategy specifies its required timeframes
2. **Automatic Resampling**: Framework resamples 1-minute data to strategy needs
3. **Precision Execution**: All strategies maintain 1-minute data for accurate stop-loss execution
4. **Signal Mapping**: Intelligent mapping between different timeframe resolutions
### Data Flow
```
Original 1min Data
Strategy.get_timeframes() → ["15min", "1h"]
Automatic Resampling
Strategy Logic (15min + 1h analysis)
Signal Generation
Map to Working Timeframe
Backtesting Engine
```
## Strategy Timeframe Interface
### StrategyBase Methods
All strategies inherit timeframe capabilities from `StrategyBase`:
```python
class MyStrategy(StrategyBase):
def get_timeframes(self) -> List[str]:
"""Specify required timeframes for this strategy"""
return ["15min", "1h"] # Strategy needs both timeframes
def initialize(self, backtester) -> None:
# Automatic resampling happens here
self._resample_data(backtester.original_df)
# Access resampled data
data_15m = self.get_data_for_timeframe("15min")
data_1h = self.get_data_for_timeframe("1h")
# Calculate indicators on each timeframe
self.indicators_15m = self._calculate_indicators(data_15m)
self.indicators_1h = self._calculate_indicators(data_1h)
self.initialized = True
```
### Data Access Methods
```python
# Get data for specific timeframe
data_15m = strategy.get_data_for_timeframe("15min")
# Get primary timeframe data (first in list)
primary_data = strategy.get_primary_timeframe_data()
# Check available timeframes
timeframes = strategy.get_timeframes()
```
## Supported Timeframes
### Standard Timeframes
- **`"1min"`**: 1-minute bars (original resolution)
- **`"5min"`**: 5-minute bars
- **`"15min"`**: 15-minute bars
- **`"30min"`**: 30-minute bars
- **`"1h"`**: 1-hour bars
- **`"4h"`**: 4-hour bars
- **`"1d"`**: Daily bars
### Custom Timeframes
Any pandas-compatible frequency string is supported:
- **`"2min"`**: 2-minute bars
- **`"10min"`**: 10-minute bars
- **`"2h"`**: 2-hour bars
- **`"12h"`**: 12-hour bars
## Strategy Examples
### Single Timeframe Strategy
```python
class SingleTimeframeStrategy(StrategyBase):
def get_timeframes(self):
return ["15min"] # Only needs 15-minute data
def initialize(self, backtester):
self._resample_data(backtester.original_df)
# Work with 15-minute data
data = self.get_primary_timeframe_data()
self.indicators = self._calculate_indicators(data)
self.initialized = True
def get_entry_signal(self, backtester, df_index):
# df_index refers to 15-minute data
if self.indicators['signal'][df_index]:
return StrategySignal("ENTRY", confidence=0.8)
return StrategySignal("HOLD", confidence=0.0)
```
### Multi-Timeframe Strategy
```python
class MultiTimeframeStrategy(StrategyBase):
def get_timeframes(self):
return ["15min", "1h", "4h"] # Multiple timeframes
def initialize(self, backtester):
self._resample_data(backtester.original_df)
# Access different timeframes
self.data_15m = self.get_data_for_timeframe("15min")
self.data_1h = self.get_data_for_timeframe("1h")
self.data_4h = self.get_data_for_timeframe("4h")
# Calculate indicators on each timeframe
self.trend_4h = self._calculate_trend(self.data_4h)
self.momentum_1h = self._calculate_momentum(self.data_1h)
self.entry_signals_15m = self._calculate_entries(self.data_15m)
self.initialized = True
def get_entry_signal(self, backtester, df_index):
# Primary timeframe is 15min (first in list)
# Map df_index to other timeframes for confirmation
# Get current 15min timestamp
current_time = self.data_15m.index[df_index]
# Find corresponding indices in other timeframes
h1_idx = self.data_1h.index.get_indexer([current_time], method='ffill')[0]
h4_idx = self.data_4h.index.get_indexer([current_time], method='ffill')[0]
# Multi-timeframe confirmation
trend_ok = self.trend_4h[h4_idx] > 0
momentum_ok = self.momentum_1h[h1_idx] > 0.5
entry_signal = self.entry_signals_15m[df_index]
if trend_ok and momentum_ok and entry_signal:
confidence = 0.9 # High confidence with all timeframes aligned
return StrategySignal("ENTRY", confidence=confidence)
return StrategySignal("HOLD", confidence=0.0)
```
### Configurable Timeframe Strategy
```python
class ConfigurableStrategy(StrategyBase):
def get_timeframes(self):
# Strategy timeframe configurable via parameters
primary_tf = self.params.get("timeframe", "15min")
return [primary_tf, "1min"] # Primary + 1min for stop-loss
def initialize(self, backtester):
self._resample_data(backtester.original_df)
primary_tf = self.get_timeframes()[0]
self.data = self.get_data_for_timeframe(primary_tf)
# Indicator parameters can also be timeframe-dependent
if primary_tf == "5min":
self.ma_period = 20
elif primary_tf == "15min":
self.ma_period = 14
else:
self.ma_period = 10
self.indicators = self._calculate_indicators(self.data)
self.initialized = True
```
## Built-in Strategy Timeframe Behavior
### Default Strategy
**Timeframes**: Configurable primary + 1min for stop-loss
```python
# Configuration
{
"name": "default",
"params": {
"timeframe": "5min" # Configurable timeframe
}
}
# Resulting timeframes: ["5min", "1min"]
```
**Features**:
- Supertrend analysis on configured timeframe
- 1-minute precision for stop-loss execution
- Optimized for 15-minute default, but works on any timeframe
### BBRS Strategy
**Timeframes**: 1min input (internal resampling)
```python
# Configuration
{
"name": "bbrs",
"params": {
"strategy_name": "MarketRegimeStrategy"
}
}
# Resulting timeframes: ["1min"]
```
**Features**:
- Uses 1-minute data as input
- Internal resampling to 15min/1h by Strategy class
- Signals mapped back to 1-minute resolution
- No double-resampling issues
## Advanced Features
### Timeframe Synchronization
When working with multiple timeframes, synchronization is crucial:
```python
def _get_synchronized_signals(self, df_index, primary_timeframe="15min"):
"""Get signals synchronized across timeframes"""
# Get timestamp from primary timeframe
primary_data = self.get_data_for_timeframe(primary_timeframe)
current_time = primary_data.index[df_index]
signals = {}
for tf in self.get_timeframes():
if tf == primary_timeframe:
signals[tf] = df_index
else:
# Find corresponding index in other timeframe
tf_data = self.get_data_for_timeframe(tf)
tf_idx = tf_data.index.get_indexer([current_time], method='ffill')[0]
signals[tf] = tf_idx
return signals
```
### Dynamic Timeframe Selection
Strategies can adapt timeframes based on market conditions:
```python
class AdaptiveStrategy(StrategyBase):
def get_timeframes(self):
# Fixed set of timeframes strategy might need
return ["5min", "15min", "1h"]
def _select_active_timeframe(self, market_volatility):
"""Select timeframe based on market conditions"""
if market_volatility > 0.8:
return "5min" # High volatility -> shorter timeframe
elif market_volatility > 0.4:
return "15min" # Medium volatility -> medium timeframe
else:
return "1h" # Low volatility -> longer timeframe
def get_entry_signal(self, backtester, df_index):
# Calculate market volatility
volatility = self._calculate_volatility(df_index)
# Select appropriate timeframe
active_tf = self._select_active_timeframe(volatility)
# Generate signal on selected timeframe
return self._generate_signal_for_timeframe(active_tf, df_index)
```
## Configuration Examples
### Single Timeframe Configuration
```json
{
"strategies": [
{
"name": "default",
"weight": 1.0,
"params": {
"timeframe": "15min",
"stop_loss_pct": 0.03
}
}
]
}
```
### Multi-Timeframe Configuration
```json
{
"strategies": [
{
"name": "multi_timeframe_strategy",
"weight": 1.0,
"params": {
"primary_timeframe": "15min",
"confirmation_timeframes": ["1h", "4h"],
"signal_timeframe": "5min"
}
}
]
}
```
### Mixed Strategy Configuration
```json
{
"strategies": [
{
"name": "default",
"weight": 0.6,
"params": {
"timeframe": "15min"
}
},
{
"name": "bbrs",
"weight": 0.4,
"params": {
"strategy_name": "MarketRegimeStrategy"
}
}
]
}
```
## Performance Considerations
### Memory Usage
- Only required timeframes are resampled and stored
- Original 1-minute data shared across all strategies
- Efficient pandas resampling with minimal memory overhead
### Processing Speed
- Resampling happens once during initialization
- No repeated resampling during backtesting
- Vectorized operations on pre-computed timeframes
### Data Alignment
- All timeframes aligned to original 1-minute timestamps
- Forward-fill resampling ensures data availability
- Intelligent handling of missing data points
## Best Practices
### 1. Minimize Timeframe Requirements
```python
# Good - minimal timeframes
def get_timeframes(self):
return ["15min"]
# Less optimal - unnecessary timeframes
def get_timeframes(self):
return ["1min", "5min", "15min", "1h", "4h", "1d"]
```
### 2. Use Appropriate Timeframes for Strategy Logic
```python
# Good - timeframe matches strategy logic
class TrendStrategy(StrategyBase):
def get_timeframes(self):
return ["1h"] # Trend analysis works well on hourly data
class ScalpingStrategy(StrategyBase):
def get_timeframes(self):
return ["1min", "5min"] # Scalping needs fine-grained data
```
### 3. Include 1min for Stop-Loss Precision
```python
def get_timeframes(self):
primary_tf = self.params.get("timeframe", "15min")
timeframes = [primary_tf]
# Always include 1min for precise stop-loss
if "1min" not in timeframes:
timeframes.append("1min")
return timeframes
```
### 4. Handle Timeframe Edge Cases
```python
def get_entry_signal(self, backtester, df_index):
# Check bounds for all timeframes
if df_index >= len(self.get_primary_timeframe_data()):
return StrategySignal("HOLD", confidence=0.0)
# Robust timeframe indexing
try:
signal = self._calculate_signal(df_index)
return signal
except IndexError:
return StrategySignal("HOLD", confidence=0.0)
```
## Troubleshooting
### Common Issues
1. **Index Out of Bounds**
```python
# Problem: Different timeframes have different lengths
# Solution: Always check bounds
if df_index < len(self.data_1h):
signal = self.data_1h[df_index]
```
2. **Timeframe Misalignment**
```python
# Problem: Assuming same index across timeframes
# Solution: Use timestamp-based alignment
current_time = primary_data.index[df_index]
h1_idx = hourly_data.index.get_indexer([current_time], method='ffill')[0]
```
3. **Memory Issues with Large Datasets**
```python
# Solution: Only include necessary timeframes
def get_timeframes(self):
# Return minimal set
return ["15min"] # Not ["1min", "5min", "15min", "1h"]
```
### Debugging Tips
```python
# Log timeframe information
def initialize(self, backtester):
self._resample_data(backtester.original_df)
for tf in self.get_timeframes():
data = self.get_data_for_timeframe(tf)
print(f"Timeframe {tf}: {len(data)} bars, "
f"from {data.index[0]} to {data.index[-1]}")
self.initialized = True
```
## Future Enhancements
### Planned Features
1. **Dynamic Timeframe Switching**: Strategies adapt timeframes based on market conditions
2. **Timeframe Confidence Weighting**: Different confidence levels per timeframe
3. **Cross-Timeframe Signal Validation**: Automatic signal confirmation across timeframes
4. **Optimized Memory Management**: Lazy loading and caching for large datasets
### Extension Points
The timeframe system is designed for easy extension:
- Custom resampling methods
- Alternative timeframe synchronization strategies
- Market-specific timeframe preferences
- Real-time timeframe adaptation

# Strategy Parameter Optimization
This directory contains comprehensive tools for optimizing trading strategy parameters using the IncrementalTrader framework.
## Overview
The strategy optimization script provides:
- **Parallel Parameter Testing**: Uses multiple CPU cores for efficient optimization
- **Configurable Supertrend Parameters**: Test different period and multiplier combinations
- **Risk Management Optimization**: Optimize stop-loss and take-profit settings
- **Multiple Timeframes**: Test strategies across different timeframes
- **Comprehensive Results**: Detailed analysis and sensitivity reports
- **Custom Parameter Ranges**: Support for custom parameter configurations
## Files
- `strategy_parameter_optimization.py` - Main optimization script
- `custom_params_example.json` - Example custom parameter configuration
- `README.md` - This documentation
## Quick Start
### 1. Basic Quick Test
Run a quick test with a smaller parameter space:
```bash
python tasks/strategy_parameter_optimization.py --quick-test --create-sample-data
```
This will:
- Create sample data if it doesn't exist
- Test a limited set of parameters for faster execution
- Use the optimal number of CPU cores automatically
### 2. Full Optimization
Run comprehensive parameter optimization:
```bash
python tasks/strategy_parameter_optimization.py \
--data-file "your_data.csv" \
--start-date "2024-01-01" \
--end-date "2024-12-31" \
--optimization-metric "sharpe_ratio"
```
### 3. Custom Parameter Ranges
Create a custom parameter file and use it:
```bash
python tasks/strategy_parameter_optimization.py \
--custom-params "tasks/custom_params_example.json" \
--max-workers 4
```
## Parameter Configuration
### Strategy Parameters
The MetaTrend strategy now supports the following configurable parameters:
| Parameter | Type | Description | Example Values |
|-----------|------|-------------|----------------|
| `timeframe` | str | Analysis timeframe | `"5min"`, `"15min"`, `"30min"`, `"1h"` |
| `supertrend_periods` | List[int] | Periods for Supertrend indicators | `[10, 12, 14]`, `[12, 15, 18]` |
| `supertrend_multipliers` | List[float] | Multipliers for Supertrend indicators | `[2.0, 2.5, 3.0]`, `[1.5, 2.0, 2.5]` |
| `min_trend_agreement` | float | Minimum agreement threshold (0.0-1.0) | `0.6`, `0.8`, `1.0` |
### Risk Management Parameters
| Parameter | Type | Description | Example Values |
|-----------|------|-------------|----------------|
| `stop_loss_pct` | float | Stop loss percentage | `0.02` (2%), `0.03` (3%) |
| `take_profit_pct` | float | Take profit percentage | `0.04` (4%), `0.06` (6%) |
### Understanding min_trend_agreement
The `min_trend_agreement` parameter controls how many Supertrend indicators must agree:
- `1.0` - All indicators must agree (original behavior)
- `0.8` - 80% of indicators must agree
- `0.6` - 60% of indicators must agree
- `0.5` - Simple majority must agree
## Usage Examples
### Example 1: Test Different Timeframes
```json
{
"timeframe": ["5min", "15min", "30min", "1h"],
"min_trend_agreement": [1.0],
"stop_loss_pct": [0.03],
"take_profit_pct": [0.06]
}
```
### Example 2: Optimize Supertrend Parameters
```json
{
"timeframe": ["15min"],
"supertrend_periods": [
[8, 10, 12],
[10, 12, 14],
[12, 15, 18],
[15, 20, 25]
],
"supertrend_multipliers": [
[1.5, 2.0, 2.5],
[2.0, 2.5, 3.0],
[2.5, 3.0, 3.5]
],
"min_trend_agreement": [0.6, 0.8, 1.0]
}
```
### Example 3: Risk Management Focus
```json
{
"timeframe": ["15min"],
"stop_loss_pct": [0.01, 0.015, 0.02, 0.025, 0.03, 0.04, 0.05],
"take_profit_pct": [0.02, 0.03, 0.04, 0.05, 0.06, 0.08, 0.10]
}
```
## Command Line Options
```bash
python tasks/strategy_parameter_optimization.py [OPTIONS]

## Performance Considerations
### System Resources
The script automatically detects your system capabilities and uses optimal worker counts:
- **CPU Cores**: Uses ~75% of available cores
- **Memory**: Limits workers based on available RAM
- **I/O**: Handles large result datasets efficiently
### Parameter Space Size
Be aware of exponential growth in parameter combinations:
- Quick test: ~48 combinations
- Full test: ~5,000+ combinations
- Custom ranges: Varies based on configuration
### Execution Time
Approximate execution times (varies by system and data size):
- Quick test: 2-10 minutes
- Medium test: 30-60 minutes
- Full test: 2-8 hours
## Data Requirements
### Data Format
The script expects CSV data with columns:
- `timestamp` - Unix timestamp in milliseconds
- `open` - Opening price
- `high` - Highest price
- `low` - Lowest price
- `close` - Closing price
- `volume` - Trading volume
### Sample Data
Use `--create-sample-data` to generate sample data for testing:
```bash
python tasks/strategy_parameter_optimization.py --create-sample-data --quick-test
```
## Advanced Usage
### 1. Distributed Optimization
For very large parameter spaces, consider running multiple instances:
```bash
# Terminal 1 - Test timeframes 5min, 15min
python tasks/strategy_parameter_optimization.py --custom-params timeframe_5_15.json
# Terminal 2 - Test timeframes 30min, 1h
python tasks/strategy_parameter_optimization.py --custom-params timeframe_30_1h.json
```
### 2. Walk-Forward Analysis
For more robust results, test across multiple time periods:
```bash
# Q1 2024
python tasks/strategy_parameter_optimization.py --start-date 2024-01-01 --end-date 2024-03-31
# Q2 2024
python tasks/strategy_parameter_optimization.py --start-date 2024-04-01 --end-date 2024-06-30
```
### 3. Custom Metrics
The script supports custom optimization metrics. See the documentation for implementation details.
## Troubleshooting
### Common Issues
1. **Memory Errors**: Reduce `--max-workers` or use `--quick-test`
2. **Data Not Found**: Use `--create-sample-data` or check file path
3. **Import Errors**: Ensure IncrementalTrader is properly installed
4. **Slow Performance**: Check system resources and reduce parameter space
### Logging
The script provides detailed logging. For debug information:
```python
import logging
logging.getLogger().setLevel(logging.DEBUG)
```
## Examples
### Quick Start Example
```bash
# Run quick optimization with sample data
python tasks/strategy_parameter_optimization.py \
--quick-test \
--create-sample-data \
--optimization-metric sharpe_ratio \
--max-workers 4
```
### Production Example
```bash
# Run comprehensive optimization with real data
python tasks/strategy_parameter_optimization.py \
--data-file "BTCUSDT_1m_2024.csv" \
--start-date "2024-01-01" \
--end-date "2024-12-31" \
--optimization-metric calmar_ratio \
--custom-params "production_params.json"
```
This comprehensive setup allows you to:
1. **Test the modified MetaTrend strategy** with configurable Supertrend parameters
2. **Run parameter optimization in parallel** using system utilities from utils.py
3. **Test multiple timeframes and risk management settings**
4. **Get detailed analysis and sensitivity reports**
5. **Use custom parameter ranges** for focused optimization
The script leverages the existing IncrementalTrader framework and integrates with the utilities you already have in place.
