Does EMA 8/21 trend rider actually work on AAPL? We tested it
We ran EMA 8/21 trend rider on AAPL through walk-forward testing and a 100-run random-entry gauntlet. 4 of 4 unseen periods positive. Beat 84 of 100 random-entry runs.
You gave up raw return for a higher win rate and a shallower drawdown. This setup is about timing and staying out of trouble, not beating the index.

This strategy made money overall, turning a 175% total return on AAPL over the period tested. The ride was fairly lumpy, with a win rate of just 42.5%, meaning you lost on more than half of your trades, but the average winning trade was big enough to more than cover the losses. The worst stretch was a 16% drawdown that lasted from late December 2024 into April 2026, so that was the most painful period to sit through. The entry timing shows a real edge, since your actual entries beat 84% of random entry runs, meaning the signal itself is doing a lot of the heavy lifting rather than the exits. The edge was consistent across all four walk-forward test periods, so the result wasn't driven by just one lucky stretch.
