This indicates the strategy performs better on less extreme oversold sweeps with some positive momentum. Increasing confirm_buffer from 0.0055 to 0.0065 and min_sweep_fraction from 0.0161 to 0.018 filters the deepest sweeps that populate the loser distribution. Slightly increasing lookback to 20 stabilizes the sweep detection without reducing opportunity count."
