Whipsaws in sideways markets; lags at turning points. Works best when ADX confirms a 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.
Open the AI Backtester with these rules pre-filled, pick a stock and a date range, and add your own stop-loss or target.
