Backtesting is a crucial step in automated crypto trading, allowing traders to test strategies on historical data before deploying them in live markets. A well-optimized strategy ensures higher profitability, lower risk, and improved adaptability to market conditions. This manual outlines how to backtest and optimize trading strategies effectively.

1. What is Backtesting?

Backtesting is the process of running a trading algorithm on historical market data to evaluate its performance. It helps answer:
 Would this strategy have been profitable in the past?
 How does it perform under different market conditions?
 What risks and drawdowns does it have?

2. Setting Up a Backtesting Environment

To conduct reliable backtesting, you’ll need:
 Historical Market Data – Price data from exchanges (candlesticks, order books).
 Backtesting Framework – Libraries like Backtrader, CCXT, or exchange-provided tools.
 Performance Metrics – ROI, Sharpe ratio, max drawdown, and win/loss ratio.
