Quick Stats

Summary

A backtest runner that keeps things inline and focused on Indian equities. You give it a symbol like SBIN or RELIANCE, it pulls data from OpenAlgo or yfinance, runs an EMA 10/20 crossover using TA-Lib, and prints stats with proper Indian delivery fees baked in. It benchmarks against NIFTY automatically and explains metrics in plain language, which is helpful if you're not steeped in quant jargon. The whole thing outputs code you paste into a Jupyter cell or run as a script, no file juggling required. Good for quick sanity checks on a strategy before you build something heavier, though you're locked into that one EMA crossover setup.
