# 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
```

## 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

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

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()}")
```
## Integration with Other Strategies
### Strategy Combination
```python
# Combine BBRS with trend-following strategy
bbrs_strategy = BBRSStrategy("bbrs")
metatrend_strategy = MetaTrendStrategy("metatrend")
# Use MetaTrend for trend direction, BBRS for entry timing
def combined_signal(bbrs_signal, metatrend_signal):
if metatrend_signal.signal_type == 'BUY' and bbrs_signal.signal_type == 'BUY':
return IncStrategySignal.BUY(confidence=0.9)
elif metatrend_signal.signal_type == 'SELL' and bbrs_signal.signal_type == 'SELL':
return IncStrategySignal.SELL(confidence=0.9)
return IncStrategySignal.HOLD()
```

# 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"
```

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
### Strengths
1. **Trend Accuracy**: High accuracy in strong trending markets
2. **False Signal Reduction**: Multiple confirmations reduce whipsaws
3. **Adaptive Sensitivity**: Different parameters capture various trend speeds
4. **Risk Management**: Clear trend reversal detection
5. **Scalability**: Works across different timeframes and markets
### Weaknesses
1. **Sideways Markets**: May generate false signals in ranging conditions
2. **Lag**: Multiple confirmations can delay entry/exit points
3. **Whipsaws**: Vulnerable to rapid trend reversals
4. **Parameter Sensitivity**: Performance depends on parameter tuning
### Optimal Market Conditions
- **Trending Markets**: Best performance in clear directional moves
- **Medium Volatility**: Works well with moderate price swings
- **Sufficient Volume**: Better signals with adequate trading volume
- **Clear Trends**: Performs best when trends last longer than indicator periods
## Usage Examples
### Basic Usage
```python
from IncrementalTrader import MetaTrendStrategy, IncTrader
# Create strategy with default parameters
strategy = MetaTrendStrategy("metatrend")
# 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})")
```
### Custom Configuration
```python
# Custom parameters for aggressive trading
strategy = MetaTrendStrategy("metatrend_aggressive", {
"timeframe": "5min",
"supertrend_periods": [5, 10, 15],
"supertrend_multipliers": [1.5, 2.0, 2.5],
"min_trend_agreement": 0.5
})
```
### Conservative Configuration
```python
# Conservative parameters for stable trends
strategy = MetaTrendStrategy("metatrend_conservative", {

# Validate input data
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
```

```
### Key Components
#### 1. Random Number Generator
```python
class RandomStrategy(IncStrategyBase):
def __init__(self, name: str, params: dict = None):
super().__init__(name, params)
# Initialize random seed for reproducibility
if self.params.get('seed') is not None:
random.seed(self.params['seed'])
np.random.seed(self.params['seed'])
self.signal_count = 0
self.last_signal_time = 0
```
#### 2. Signal Generation Process
```python
def _process_aggregated_data(self, timestamp: int, ohlcv: tuple) -> IncStrategySignal:
open_price, high, low, close, volume = ohlcv
# Check signal frequency constraint
if not self._should_generate_signal(timestamp):
return IncStrategySignal.HOLD()
# Generate random signal
rand_val = random.random()
if rand_val < self.params['buy_probability']:
signal_type = 'BUY'
elif rand_val < (self.params['buy_probability'] + self.params['sell_probability']):
signal_type = 'SELL'
else:
signal_type = 'HOLD'
# Generate random confidence
confidence = random.uniform(
self.params['min_confidence'],
self.params['max_confidence']
)
# Create signal with metadata
if signal_type == 'BUY':
self.signal_count += 1
self.last_signal_time = timestamp
return IncStrategySignal.BUY(
confidence=confidence,
metadata=self._create_metadata(timestamp, rand_val, signal_type)
)
elif signal_type == 'SELL':
self.signal_count += 1
self.last_signal_time = timestamp
return IncStrategySignal.SELL(
confidence=confidence,
metadata=self._create_metadata(timestamp, rand_val, signal_type)
)
return IncStrategySignal.HOLD()
```
#### 3. Signal Frequency Control
```python
def _should_generate_signal(self, timestamp: int) -> bool:
"""Control signal generation frequency."""
# Check minimum time between signals
min_interval = self.params.get('min_signal_interval_minutes', 0) * 60 * 1000
if timestamp - self.last_signal_time < min_interval:
return False
# Check maximum signals per day
max_daily_signals = self.params.get('max_daily_signals', float('inf'))
if self.signal_count >= max_daily_signals:
# Reset counter if new day (simplified)
if self._is_new_day(timestamp):
self.signal_count = 0
else:
return False
return True
```

def custom_signal_generation(self, timestamp: int) -> str:
"""Custom signal generation with time-based probabilities."""
# Vary probabilities based on time of day
hour = datetime.fromtimestamp(timestamp / 1000).hour
if 9 <= hour <= 16: # Market hours
buy_prob = 0.15
sell_prob = 0.15
else: # After hours
buy_prob = 0.05
sell_prob = 0.05
rand_val = random.random()
if rand_val < buy_prob:
return 'BUY'
elif rand_val < buy_prob + sell_prob:
return 'SELL'
return 'HOLD'
```
### Confidence Distribution Modeling
```python
def generate_realistic_confidence(self) -> float:
"""Generate confidence using beta distribution for realism."""
# Beta distribution parameters for realistic confidence
alpha = 2.0 # Shape parameter
beta = 2.0 # Shape parameter
# Generate beta-distributed confidence
beta_sample = np.random.beta(alpha, beta)
# Scale to desired range
min_conf = self.params['min_confidence']
max_conf = self.params['max_confidence']
return min_conf + beta_sample * (max_conf - min_conf)
```
### Market Regime Simulation
```python
def simulate_market_regimes(self, timestamp: int) -> dict:
"""Simulate different market regimes for testing."""
# Simple regime switching based on time
regime_cycle = (timestamp // (24 * 60 * 60 * 1000)) % 3
if regime_cycle == 0: # Bull market
return {

```
## Implementation Notes
### Memory Efficiency
- **Minimal State**: Only tracks signal count and timing
- **No Indicators**: No technical indicators to maintain
- **Constant Memory**: O(1) memory usage
### 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
}
```

# 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

```python
class SMAStrategy(IncStrategyBase):
def __init__(self, name: str, params: dict = None):
default_params = {
"timeframe": "15min",
"fast_period": 10,

}
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()
```
