Supertrend double-flip option scalp

A YouTube option-scalping rule, rebuilt from the trader's own notebook: on NIFTY 5-minute candles, buy the at-the-money call (put) when Supertrend (10,1) and (10,3) are both up (down), one of them has just flipped, and the candle closes strong. 10-point stop, 20-point target on the index, entries before 2 pm. The video claims 62% winners; we find about 35% and a loss after costs. One row per trade.
