9:18 short straddle with a profit lock

A popular YouTube intraday straddle, rebuilt from the trader's own backtest settings: sells the at-the-money NIFTY call and put at 9:18, stops each leg on its own, closes the day at a ₹ stop or target, and once it is ₹1,500 up locks break-even and trails it ₹500 at a time. Out by 2:45. One row per day.
