Diagnosis

This strategy made a solid 128% total return over 61 trades, but the ride was very lumpy, not steady. The worst stretch was a brutal 37.79% drawdown that lasted over a year from September 2021 to November 2022, which is where the pain really concentrated. The win rate is only 41%, meaning most trades lost money, but the winners were big enough to more than cover the losses. The entry timing edge is strong, beating 86% of random entry runs, so the specific entry signal is carrying the result rather than the exits doing the heavy lifting. The edge was also consistent, as the strategy was profitable in all four walk-forward test periods, showing the pattern works across different market conditions rather than coming from just one lucky stretch.
