Diagnosis

This strategy made money overall, turning a 216% gain on META with a high win rate of nearly 84%, meaning most trades were winners. However, the ride was not smooth; it suffered a steep 28% drawdown from late February to mid-April 2025, which is where it hurt the most. The entry timing was excellent, beating all 100 random-entry tests, so the setup for getting in is clearly carrying the result rather than the exits. The edge was also consistent, showing up profitably in all four test periods, so the performance isn't just from one lucky stretch. In short, the strategy worked well but had one rough patch that you would have had to sit through.
