Backtesting Trading Strategies

Before you risk real money on that trading idea, run it through historical data with this backtesting framework. It comes with eight prebuilt strategies (SMA crossover, RSI reversal, MACD, Bollinger bands, etc.) and calculates the metrics that actually matter: Sharpe ratio, max drawdown, win rate, profit factor. The parameter optimization via grid search is handy for finding better configurations without manual trial and error. Built on yfinance for data fetching, so you can test against both crypto and traditional assets. The equity curve visualization and trade-by-trade logs make it easy to see where your strategy breaks down. Solid starting point if you're tired of backtesting strategies in spreadsheets.
