Crypto Backtest

Crypto futures backtesting engine with built-in EMA, RSI, MACD, and Bollinger Band strategies. Fetches OHLCV data from any ccxt-supported exchange (Bybit, Binance, OKX, etc.), runs multi-strategy sweeps, calculates win rate / PnL / drawdown, and exports results to JSON. Use when backtesting trading strategies, comparing parameter combinations, evaluating crypto trading signals, or building a quantitative trading pipeline.
