4 · Risk

Low win rate by design — most breakouts fail small, a few run far.

Test assumptions: long only, one position per stock, next-open fills, 0.2% round-trip cost, split-adjusted prices without dividends, current Nifty 50 members (survivorship bias). Past results do not predict future returns.

5 · Test it on any stock

Open the AI Backtester with these rules pre-filled, pick a stock and a date range, and add your own stop-loss or target.

Buy when close rises above the previous 55-day high, sell when close falls below the previous 20-day low.
