Diagnosis

This strategy made money overall, turning a 44.44% total return over 79 trades, and it won on nearly three out of every four trades. The ride was not smooth, with a maximum drawdown of -14.28% that stretched from late 2017 through early 2020, meaning that period was where the strategy hurt the most. The result is not driven by just a few lucky trades, because the consistency test shows it was profitable in three out of four separate time periods, so the edge showed up across different market conditions. The entry timing is strong, beating 80% of random entry attempts, which means the entry signal itself is doing the heavy lifting rather than the exits.
