Backtesting Package

A Python package for backtesting and analyzing trading strategies over various time periods. This package allows users to easily split data, run backtests, optimize strategies, and perform equity curve analysis.

Features

• Split Data Periods: Split time series data into yearly, monthly, or custom periods.
• Backtest: Run backtests on trading strategies across different periods.
• Equity Curve Analysis: Analyze and visualize equity curves for deeper insight into performance.
• Monte Carlo Simulation: Perform Monte Carlo simulations to evaluate strategy robustness.
• Parameter Optimization: Optimize strategy parameters for better performance.

Installation

You can install the package using pip: pip install backtest_equities

Usage

Import the Package

import backtest_equities as bt

1. Split Data into Periods You can split your time series data (such as stock price data) into periods for different types of analysis.

import pandas as pd

Assuming df is your time series data with a DateTime index

df = pd.read_csv('your-data.csv', index_col='Date', parse_dates=True)

Split the data into yearly periods

split_data = bt.split_periods(df, periods_for_split='yearly')

2. Run a Backtest Over Periods Run a backtest on the split data for different periods.

Define your strategy parameters

side = 'long' SL_type = 'fixed' SL = 0.02 SL_spike_out = False TP = 0.05 TS = 0.03

Run backtest over the split periods

backtest_results = bt.backtest_over_periods(split_data, side, SL_type, SL, SL_spike_out, TP, TS)

Analyze the backtest results

for result in backtest_results: print(result)

3. Optimize Strategy Parameters You can optimize your strategy by testing different parameters.

Define parameter ranges

param_ranges = { 'SL': [0.01, 0.02, 0.03], 'TP': [0.03, 0.05, 0.07] }

Optimize parameters

optimal_params = bt.optimize_parameters(df, param_ranges) print("Optimal Parameters:", optimal_params)

4. Equity Curve Analysis Visualize and analyze the equity curves from the backtest.

Perform equity curve analysis

bt.equity_curve_analysis(backtest_results)

5. Monte Carlo Simulation Run a Monte Carlo simulation to assess the strategy’s robustness.

Run Monte Carlo simulation with 1000 iterations

bt.monte_carlo_simulation(backtest_results, iterations=1000)

Example Workflow

Here’s a full workflow example of using the package to split data, backtest, and analyze results.

import pandas as pd import your_package_name as bt

Load data

df = pd.read_csv('your-data.csv', index_col='Date', parse_dates=True)

Split into yearly periods

split_data = bt.split_periods(df, periods_for_split='yearly')

Run backtest on each period

backtest_results = bt.backtest_over_periods(split_data, side='long', SL_type='fixed', SL=0.02, SL_spike_out=False, TP=0.05, TS=0.03)

Perform equity curve analysis

bt.equity_curve_analysis(backtest_results)

Run Monte Carlo simulation for further analysis

bt.monte_carlo_simulation(backtest_results, iterations=1000)
