# Cycles - Advanced Trading Strategy Backtesting Framework
A sophisticated Python framework for backtesting cryptocurrency trading strategies with multi-timeframe analysis, strategy combination, and advanced signal processing.
## Features
- **Multi-Strategy Architecture**: Combine multiple trading strategies with configurable weights and rules
- **Multi-Timeframe Analysis**: Strategies can operate on different timeframes (1min, 5min, 15min, 1h, etc.)
- **Advanced Strategies**:
- **Default Strategy**: Meta-trend analysis using multiple Supertrend indicators
- **BBRS Strategy**: Bollinger Bands + RSI with market regime detection
- **Flexible Signal Combination**: Weighted consensus, majority voting, any/all combinations
- **Precise Stop-Loss**: 1-minute precision for accurate risk management
- **Comprehensive Backtesting**: Detailed performance metrics and trade analysis
- **Data Visualization**: Interactive charts and performance plots
## Quick Start
### Prerequisites
- Python 3.8+
- [uv](https://github.com/astral-sh/uv) package manager (recommended)
### Installation
```bash
# Clone the repository
git clone <repository-url>
cd Cycles
# Install dependencies with uv
uv sync
# Or install with pip
pip install -r requirements.txt
```
### Running Backtests
Use the `uv run` command to execute backtests with different configurations:
```bash
# Run default strategy on 5-minute timeframe
uv run .\main.py .\configs\config_default_5min.json
# Run default strategy on 15-minute timeframe
uv run .\main.py .\configs\config_default.json
# Run BBRS strategy with market regime detection
uv run .\main.py .\configs\config_bbrs.json
# Run combined strategies
uv run .\main.py .\configs\config_combined.json
```
### Configuration Examples
#### Default Strategy (5-minute timeframe)
```bash
uv run .\main.py .\configs\config_default_5min.json
```
#### BBRS Strategy with Multi-timeframe Analysis
```bash
uv run .\main.py .\configs\config_bbrs_multi_timeframe.json
```
#### Combined Strategies with Weighted Consensus
```bash
uv run .\main.py .\configs\config_combined.json
```
## Configuration
Strategies are configured using JSON files in the `configs/` directory:
```json
{
"start_date": "2024-01-01",
"stop_date": "2024-01-31",
"initial_usd": 10000,
"timeframes": ["15min"],
"stop_loss_pcts": [0.03, 0.05],
"strategies": [
{
"name": "default",
"weight": 1.0,
"params": {
"timeframe": "15min"
}
}
],
"combination_rules": {
"entry": "any",
"exit": "any",
"min_confidence": 0.5
}
}
```
### Available Strategies
1. **Default Strategy**: Meta-trend analysis using Supertrend indicators
2. **BBRS Strategy**: Bollinger Bands + RSI with market regime detection
### Combination Rules
- **Entry**: `any`, `all`, `majority`, `weighted_consensus`
- **Exit**: `any`, `all`, `priority` (prioritizes stop-loss signals)

- **[Strategies](./docs/strategies.md)** - Individual strategy implementations and usage
- **[Timeframe System](./docs/timeframe_system.md)** - Advanced timeframe management and multi-timeframe strategies
- **[Analysis](./docs/analysis.md)** - Technical analysis components
- **[Storage Utils](./docs/utils_storage.md)** - Data storage and retrieval
- **[System Utils](./docs/utils_system.md)** - System utilities
## Examples
### Single Strategy Backtest
```bash
# Test default strategy on different timeframes
uv run .\main.py .\configs\config_default.json # 15min
uv run .\main.py .\configs\config_default_5min.json # 5min
```
### Multi-Strategy Backtest
```bash
# Combine multiple strategies with different weights
uv run .\main.py .\configs\config_combined.json
```
### Custom Configuration
Create your own configuration file and run:
```bash
uv run .\main.py .\configs\your_config.json
```
## Output
Backtests generate:
- **CSV Results**: Detailed performance metrics per timeframe/strategy
- **Trade Log**: Individual trade records with entry/exit details
- **Performance Charts**: Visual analysis of strategy performance (in debug mode)
- **Log Files**: Detailed execution logs

## Implementation Details
### Buffer Size Calculations
#### DefaultStrategy
```python
def get_minimum_buffer_size(self) -> Dict[str, int]:
primary_tf = self.params.get("timeframe", "15min")
# Supertrend needs 50 periods for reliable calculation
if primary_tf == "15min":
return {"15min": 50, "1min": 750} # 50 * 15 = 750 minutes
elif primary_tf == "5min":
return {"5min": 50, "1min": 250} # 50 * 5 = 250 minutes
elif primary_tf == "30min":
return {"30min": 50, "1min": 1500} # 50 * 30 = 1500 minutes
elif primary_tf == "1h":
return {"1h": 50, "1min": 3000} # 50 * 60 = 3000 minutes
else: # 1min
return {"1min": 50}
```
#### BBRSStrategy
```python
def get_minimum_buffer_size(self) -> Dict[str, int]:
bb_period = self.params.get("bb_period", 20)
rsi_period = self.params.get("rsi_period", 14)
# Need max of BB and RSI periods plus warmup
min_periods = max(bb_period, rsi_period) + 10
return {"1min": min_periods}
```
### Error Recovery Strategy
1. **State Validation**: Periodic validation of indicator states
2. **Graceful Degradation**: Fall back to batch calculation if incremental fails
3. **Automatic Recovery**: Reinitialize from buffer data when corruption detected
4. **Monitoring**: Track error rates and performance metrics
### Performance Targets
- **Incremental Update**: <1ms per data point ✅
- **Signal Generation**: <10ms per strategy ✅
- **Memory Usage**: <100MB per strategy (bounded by buffer size) ✅
- **Accuracy**: 99.99% identical to batch calculations ✅
### Testing Strategy
1. **Unit Tests**: Test each component in isolation
2. **Integration Tests**: Test strategy combinations
3. **Performance Tests**: Benchmark against current implementation
4. **Accuracy Tests**: Validate against known good results
5. **Stress Tests**: Test with high-frequency data
6. **Memory Tests**: Validate memory usage bounds
## Risk Mitigation
### Technical Risks

# Real-Time Strategy Architecture - Technical Specification
## Overview
This document outlines the technical specification for updating the trading strategy system to support real-time data processing with incremental calculations. The current architecture processes entire datasets during initialization, which is inefficient for real-time trading where new data arrives continuously.
## Current Architecture Issues
### Problems with Current Implementation
1. **Initialization-Heavy Design**: All calculations performed during `initialize()` method
2. **Full Dataset Processing**: Entire historical dataset processed on each initialization
3. **Memory Inefficient**: Stores complete calculation history in arrays
4. **No Incremental Updates**: Cannot add new data without full recalculation
5. **Performance Bottleneck**: Recalculating years of data for each new candle
6. **Index-Based Access**: Signal generation relies on pre-calculated arrays with fixed indices
### Current Strategy Flow
```
Data → initialize() → Full Calculation → Store Arrays → get_signal(index)
```
## Target Architecture: Incremental Calculation
### New Strategy Flow
```
Initial Data → initialize() → Warm-up Calculation → Ready State
New Data Point → calculate_on_data() → Update State → get_signal()
```
## Technical Requirements
### 1. Base Strategy Interface Updates
#### New Abstract Methods
```python
@abstractmethod
def get_minimum_buffer_size(self) -> Dict[str, int]:
"""
Return minimum data points needed for each timeframe.
Returns:
Dict[str, int]: {timeframe: min_points} mapping
Example:
{"15min": 50, "1min": 750} # 50 15min candles = 750 1min candles
"""
pass
@abstractmethod
def calculate_on_data(self, new_data_point: Dict, timestamp: pd.Timestamp) -> None:
"""
Process a single new data point incrementally.
Args:
new_data_point: OHLCV data point {open, high, low, close, volume}
timestamp: Timestamp of the data point
"""
pass
@abstractmethod
def supports_incremental_calculation(self) -> bool:
"""
Whether strategy supports incremental calculation.
Returns:
bool: True if incremental mode supported
"""
pass
```
#### New Properties and Methods
```python
@property
def calculation_mode(self) -> str:
"""Current calculation mode: 'initialization' or 'incremental'"""
return self._calculation_mode
@property
def is_warmed_up(self) -> bool:
"""Whether strategy has sufficient data for reliable signals"""
return self._is_warmed_up
def reset_calculation_state(self) -> None:
"""Reset internal calculation state for reinitialization"""
pass
def get_current_state_summary(self) -> Dict:
"""Get summary of current calculation state for debugging"""
pass
```
### 2. Internal State Management
#### State Variables
Each strategy must maintain:
```python
class StrategyBase:
def __init__(self, ...):
# Calculation state
self._calculation_mode = "initialization" # or "incremental"
self._is_warmed_up = False
self._data_points_received = 0
# Timeframe-specific buffers
self._timeframe_buffers = {} # {timeframe: deque(maxlen=buffer_size)}
self._timeframe_last_update = {} # {timeframe: timestamp}
# Indicator states (strategy-specific)
self._indicator_states = {}
# Signal generation state
self._last_signals = {} # Cache recent signals
self._signal_history = deque(maxlen=100) # Recent signal history
```
#### Buffer Management
```python
def _update_timeframe_buffers(self, new_data_point: Dict, timestamp: pd.Timestamp):
"""Update all timeframe buffers with new data point"""
def _should_update_timeframe(self, timeframe: str, timestamp: pd.Timestamp) -> bool:
"""Check if timeframe should be updated based on timestamp"""
def _get_timeframe_buffer(self, timeframe: str) -> pd.DataFrame:
"""Get current buffer for specific timeframe"""
```
### 3. Strategy-Specific Requirements
#### DefaultStrategy (Supertrend-based)
```python
class DefaultStrategy(StrategyBase):
def get_minimum_buffer_size(self) -> Dict[str, int]:
primary_tf = self.params.get("timeframe", "15min")
if primary_tf == "15min":
return {"15min": 50, "1min": 750}
elif primary_tf == "5min":
return {"5min": 50, "1min": 250}
# ... other timeframes
def _initialize_indicator_states(self):
"""Initialize Supertrend calculation states"""
self._supertrend_states = [
SupertrendState(period=10, multiplier=3.0),
SupertrendState(period=11, multiplier=2.0),
SupertrendState(period=12, multiplier=1.0)
]
def _update_supertrend_incrementally(self, ohlc_data):
"""Update Supertrend calculations with new data"""
# Incremental ATR calculation
# Incremental Supertrend calculation
# Update meta-trend based on all three Supertrends
```
#### BBRSStrategy (Bollinger Bands + RSI)
```python
class BBRSStrategy(StrategyBase):
def get_minimum_buffer_size(self) -> Dict[str, int]:
bb_period = self.params.get("bb_period", 20)
rsi_period = self.params.get("rsi_period", 14)
min_periods = max(bb_period, rsi_period) + 10 # +10 for warmup
return {"1min": min_periods}
def _initialize_indicator_states(self):
"""Initialize BB and RSI calculation states"""
self._bb_state = BollingerBandsState(period=self.params.get("bb_period", 20))
self._rsi_state = RSIState(period=self.params.get("rsi_period", 14))
self._market_regime_state = MarketRegimeState()
def _update_indicators_incrementally(self, price_data):
"""Update BB, RSI, and market regime with new data"""
# Incremental moving average for BB
# Incremental RSI calculation
# Market regime detection update
```
#### RandomStrategy
```python
class RandomStrategy(StrategyBase):
def get_minimum_buffer_size(self) -> Dict[str, int]:
return {"1min": 1} # No indicators needed
def supports_incremental_calculation(self) -> bool:
return True # Always supports incremental
```
### 4. Indicator State Classes
#### Base Indicator State
```python
class IndicatorState(ABC):
"""Base class for maintaining indicator calculation state"""
@abstractmethod
def update(self, new_value: float) -> float:
"""Update indicator with new value and return current indicator value"""
pass
@abstractmethod
def is_warmed_up(self) -> bool:
"""Whether indicator has enough data for reliable values"""
pass
@abstractmethod
def reset(self) -> None:
"""Reset indicator state"""
pass
```
#### Specific Indicator States
```python
class MovingAverageState(IndicatorState):
"""Maintains state for incremental moving average calculation"""
class RSIState(IndicatorState):
"""Maintains state for incremental RSI calculation"""
class SupertrendState(IndicatorState):
"""Maintains state for incremental Supertrend calculation"""
class BollingerBandsState(IndicatorState):
"""Maintains state for incremental Bollinger Bands calculation"""
```
### 5. Data Flow Architecture
#### Initialization Phase
```
1. Strategy.initialize(backtester)
2. Strategy._resample_data(original_data)
3. Strategy._initialize_indicator_states()
4. Strategy._warm_up_with_historical_data()
5. Strategy._calculation_mode = "incremental"
6. Strategy._is_warmed_up = True
```
#### Real-Time Processing Phase
```
1. New data arrives → StrategyManager.process_new_data()
2. StrategyManager → Strategy.calculate_on_data(new_point)
3. Strategy._update_timeframe_buffers()
4. Strategy._update_indicators_incrementally()
5. Strategy ready for get_entry_signal()/get_exit_signal()
```
### 6. Performance Requirements
#### Memory Efficiency
- Maximum buffer size per timeframe: configurable (default: 200 periods)
- Use `collections.deque` with `maxlen` for automatic buffer management
- Store only essential state, not full calculation history
#### Processing Speed
- Target: <1ms per data point for incremental updates
- Target: <10ms for signal generation
- Batch processing support for multiple data points
#### Accuracy Requirements
- Incremental calculations must match batch calculations within 0.01% tolerance
- Indicator values must be identical to traditional calculation methods
- Signal timing must be preserved exactly
### 7. Error Handling and Recovery
#### State Corruption Recovery
```python
def _validate_calculation_state(self) -> bool:
"""Validate internal calculation state consistency"""
def _recover_from_state_corruption(self) -> None:
"""Recover from corrupted calculation state"""
# Reset to initialization mode
# Recalculate from available buffer data
# Resume incremental mode
```
#### Data Gap Handling
```python
def handle_data_gap(self, gap_duration: pd.Timedelta) -> None:
"""Handle gaps in data stream"""
if gap_duration > self._max_acceptable_gap:
self._trigger_reinitialization()
else:
self._interpolate_missing_data()
```
### 8. Backward Compatibility
#### Compatibility Layer
- Existing `initialize()` method continues to work
- New methods are optional with default implementations
- Gradual migration path for existing strategies
- Fallback to batch calculation if incremental not supported
#### Migration Strategy
1. Phase 1: Add new interface with default implementations
2. Phase 2: Implement incremental calculation for each strategy
3. Phase 3: Optimize and remove batch calculation fallbacks
4. Phase 4: Make incremental calculation mandatory
### 9. Testing Requirements
#### Unit Tests
- Test incremental vs. batch calculation accuracy
- Test state management and recovery
- Test buffer management and memory usage
- Test performance benchmarks
#### Integration Tests
- Test with real-time data streams
- Test strategy manager coordination
- Test error recovery scenarios
- Test memory usage over extended periods
#### Performance Tests
- Benchmark incremental vs. batch processing
- Memory usage profiling
- Latency measurements for signal generation
- Stress testing with high-frequency data
### 10. Configuration and Monitoring
#### Configuration Options
```python
STRATEGY_CONFIG = {
"calculation_mode": "incremental", # or "batch"
"buffer_size_multiplier": 2.0, # multiply minimum buffer size
"max_acceptable_gap": "5min", # max data gap before reinitialization
"enable_state_validation": True, # enable periodic state validation
"performance_monitoring": True # enable performance metrics
}
```
#### Monitoring Metrics
- Calculation latency per strategy
- Memory usage per strategy
- State validation failures
- Data gap occurrences
- Signal generation frequency
This specification provides the foundation for implementing efficient real-time strategy processing while maintaining accuracy and reliability.

- Note: Trading strategies are detailed in `strategies.md`.
## Class: `RSI`
@@ -16,91 +15,64 @@ 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)**:
1. **Average Gain (AvgU)** and **Average Loss (AvgD)** over 14 periods:
$$
RS = \\frac{\\text{AvgU}}{\\text{AvgD}}
\text{AvgU} = \frac{\sum \text{Upward Price Changes}}{14}, \quad \text{AvgD} = \frac{\sum \text{Downward Price Changes}}{14}
$$
5. **RSI**:
2. **Relative Strength (RS)**:
$$
RSI = 100 - \\frac{100}{1 + RS}
RS = \frac{\text{AvgU}}{\text{AvgD}}
$$
3. **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)`
### `__init__(self, period: int = 14)`
- **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}`).
- **Parameters**:
- `period` (int, optional): The period for RSI calculation. Defaults to 14. Must be a positive integer.
### `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.
- **Description**: Calculates the RSI and adds it as an 'RSI' column to the input DataFrame. Handles cases where data length is less than the period by returning the original DataFrame with a warning.
- **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.
- `data_df` (pd.DataFrame): DataFrame with historical price data. Must contain the `price_column`.
- `price_column` (str, optional): The name of the column containing price data. Defaults to 'close'.
- **Returns**: `pd.DataFrame` - The input DataFrame with an added 'RSI' column (containing `np.nan` for initial periods where RSI cannot be calculated). Returns a copy of the original DataFrame if the period is larger than the number of data points.
## Class: `BollingerBands`
Found in `cycles/Analysis/boillinger_band.py`.
Calculates Bollinger Bands.
## **Bollinger Bands**
### Mathematical Model
1. **Middle Band**: Simple Moving Average (SMA) over `period`.
1. **Middle Band**: 20-day Simple Moving Average (SMA)
$$
\\text{Middle Band} = \\text{SMA}(\\text{price}, \\text{period})
\text{Middle Band} = \frac{1}{20} \sum_{i=1}^{20} \text{Close}_{t-i}
$$
2. **Standard Deviation (σ)**: Standard deviation of price over `period`.
3. **Upper Band**: Middle Band + `num_std` × σ
2. **Upper Band**: Middle Band + 2 × 20-day Standard Deviation (σ)
$$
\\text{Upper Band} = \\text{Middle Band} + \\text{num_std} \\times \\sigma_{\\text{period}}
\text{Upper Band} = \text{Middle Band} + 2 \times \sigma_{20}
$$
4. **Lower Band**: Middle Band − `num_std` × σ
3. **Lower Band**: Middle Band − 2 × 20-day Standard Deviation (σ)
$$
\\text{Lower Band} = \\text{Middle Band} - \\text{num_std} \\times \\sigma_{\\text{period}}
\text{Lower Band} = \text{Middle Band} - 2 \times \sigma_{20}
$$
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)`
### `__init__(self, period: int = 20, std_dev_multiplier: float = 2.0)`
- **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.
- `period` (int, optional): The period for the moving average and standard deviation. Defaults to 20. Must be a positive integer.
- `std_dev_multiplier` (float, optional): The number of standard deviations for the upper and lower bands. Defaults to 2.0. Must be positive.
### `calculate(self, data_df: pd.DataFrame, price_column: str = 'close') -> pd.DataFrame`
- **Description**: Calculates Bollinger Bands and adds 'SMA' (Simple Moving Average), 'UpperBand', and 'LowerBand' columns to the DataFrame.
- **Parameters**:
- `data_df` (pd.DataFrame): DataFrame with price data. Must include the `price_column`.
- `price_column` (str, optional): The name of the column containing the price data (e.g., 'close'). Defaults to 'close'.
- **Returns**: `pd.DataFrame` - The original DataFrame with added columns: 'SMA', 'UpperBand', 'LowerBand'.

# 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**:

## 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
- **Error Handling**: Individual strategy failures don't crash the system
- **Logging**: Comprehensive logging for debugging and monitoring
## Best Practices
1. **Strategy Design:**
- Specify minimal required timeframes
- Include 1min for stop-loss precision
- Use confidence levels effectively
2. **Signal Combination:**
- Use `any` for exits (risk management)
- Use `weighted_consensus` for entries
- Set appropriate minimum confidence levels
3. **Error Handling:**
- Implement robust initialization checks
- Handle missing data gracefully
- Log strategy-specific warnings
4. **Testing:**
- Test strategies individually before combining
- Validate timeframe requirements
- Monitor memory usage with large datasets
## Troubleshooting
### Common Issues
1. **Timeframe Mismatches:**
- Ensure strategy specifies correct timeframes
- Check data availability for all timeframes
2. **Signal Conflicts:**
- Review combination rules
- Adjust confidence thresholds
- Monitor strategy weights
3. **Performance Issues:**
- Minimize timeframe requirements
- Optimize indicator calculations
- Use efficient pandas operations
### Debugging Tips
- Enable detailed logging: `logging.basicConfig(level=logging.DEBUG)`
- Use strategy summary: `manager.get_strategy_summary()`
- Test individual strategies before combining
- Monitor signal confidence levels

## 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"):

### 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
