This strategy made money overall, turning a 100% gain over its life, but the ride was very lumpy. The worst stretch was a brutal 32% drawdown that lasted from late April to early November 2022, which is where the strategy hurt the most. With 38 trades and a 71% win rate, the result is not driven by just a few lucky trades, but the average gain per trade is only 2%, so you need many small wins to add up. The entry-timing edge is strong, as real entries beat 83% of random entries, meaning the entry signal itself is carrying the result rather than the exits doing the heavy lifting. The consistency figure shows the edge was steady, with the strategy profitable in 3 out of 4 walk-forward periods, so the edge did not come from just one lucky stretch.
