This does what you need when you're not sure which strategy actually works better on a given stock. Point it at a symbol and it runs multiple strategies (EMA crossover, RSI, Donchian, Supertrend) on the same data, then spits out a comparison table with returns, Sharpe, drawdown, and win rates. It also benchmarks against NIFTY so you know if you're even beating the index. Uses TA-Lib for indicators, handles Indian delivery fees correctly, and cleans signals with exrem. The long vs short mode is handy for testing directional bias. Saves you from running separate backtests and eyeballing results across terminal windows. Creates overlaid equity curves in Plotly so you can see divergence visually.
