4 · Risk

Many small losses; profits come from the minority of breakouts that trend.

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 makes a new 20-day high, sell when close falls below the 10-day low.
