A setup can look perfect on a screenshot and still fail over a meaningful sample. I would define the rules before looking at results, record every qualifying trade, and compare outcomes across different market conditions. What metrics would you require before trusting this idea with real risk? For a fair comparison, I would also track expectancy, average loss, maximum drawdown, and the number of trades rather than focusing on win rate alone. This matters because a high win rate can still hide poor risk control. In your experience, what specific rule or metric best separates disciplined use of this prop firms topic from guesswork?
