Does Parabolic SAR flip actually work on NVDA? We tested it

This strategy made a substantial profit, turning a 1,128% total return over 73 trades, but the ride was very lumpy. The worst stretch was a brutal 37% drawdown that lasted from November 2024 to July 2026, which is where the strategy hurt the most. The win rate is just under 55%, meaning it wins slightly more than it loses, but the average trade gained over 4%, so the winners were bigger than the losers. The entry timing has a real edge, beating 80% of random entries, so the entry signal itself is doing a lot of the heavy lifting rather than the exits. The edge was also consistent, showing up in three out of four walk-forward periods, so the result is not just from one lucky streak.
