Diagnosis

This strategy made money, turning a 28% total return on GOOGL over 17 trades. The ride was fairly steady, with a 76% win rate and an average gain of 1.5% per trade, but it did have one rough patch where it lost 7.7% over just a few days in early August 2024. That single drawdown was the worst moment, and it came from a concentrated stretch of losses. The result is not driven by just a few lucky trades, because the entry timing edge is strong, with real entries beating 90% of random entry runs, meaning the entry itself is carrying the result. The edge also shows up consistently, as the strategy was profitable in 3 out of 4 walk forward periods, so the performance is not from one lucky streak.
