cerebro-backtester 10.0.2

A backtesting framework for evaluating trading strategies on historical market data with features like stop-loss, take-profit, trailing stop, and risk management.

Backtest Framework

This Python backtesting framework allows you to evaluate trading strategies on historical market data. It supports stop-loss (SL), take-profit (TP), trailing stop (TS), and various risk management features. You can backtest both long and short strategies with configurable settings for transaction costs and balance management.

Features Backtest long and short trading strategies Configurable stop-loss (SL) types: ATR-based, standard deviation (SD)-based, and percentage-based Take-profit and trailing stop functionality Risk management through percentage-based position sizing Transaction costs handling Equity curve and drawdown tracking Detailed trade history, including entry and exit points, stop-loss updates, and trade returns

Usage/Examples

Example 1: Simple Long Strategy with ATR-based Stop Loss

import pandas as pd
from backtest import Backtest

# Example historical data
data = pd.DataFrame({
    'Close': [100, 102, 101, 104, 106],
    'High': [101, 103, 102, 105, 107],
    'Low': [99, 100, 100, 103, 105],
    'buy_signal': [1, 0, 0, 1, 0],
    'sell_signal': [0, 0, 0, 0, 1]
})

# Configure and run the backtest
backtest = Backtest(
    info=data,
    side='long',
    SL_type='atr',
    SL=2,  # 2x ATR for stop-loss
    SL_spike_out=True,
    TP=3,  # 3x ATR for take-profit
    TS=True  # Enable trailing stop
)
backtest.run()

# Analyze results
print(backtest.info[['equity_curve', 'drawdown', 'trade_return_hist']])

Example 2: Short Strategy with Standard Deviation-based Stop Loss

import pandas as pd
from backtest import Backtest

# Example historical data
data = pd.DataFrame({
    'Close': [100, 102, 101, 98, 96],
    'High': [101, 103, 102, 100, 97],
    'Low': [99, 100, 100, 95, 94],
    'buy_signal': [0, 0, 0, 1, 0],
    'sell_signal': [1, 0, 1, 0, 0]
})

# Configure and run the backtest
backtest = Backtest(
    info=data,
    side='short',
    SL_type='sd',
    SL=1,  # 1x standard deviation for stop-loss
    SL_spike_out=False,
    TP=2,  # 2x standard deviation for take-profit
    TS=False  # Disable trailing stop
)
backtest.run()

# Analyze results
print(backtest.info[['equity_curve', 'drawdown', 'trade_return_hist']])
