This strategy made money overall, turning a 75.5% total return on IWM, but the ride was lumpy. The worst stretch was a 16.93% drawdown that lasted over a year from March 2021 to June 2022, which is where the pain really concentrated. With only 39.66% of trades being winners, the profit came from a few big winners that made up for many small losers. The entry timing shows a real edge, beating 78% of random entry runs, so the setup itself is picking good spots to get in. The edge was consistent across all four test periods, meaning the strategy worked steadily over time rather than relying on one lucky streak.
