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

This strategy made money overall, turning a 229% total return, but the ride was far from smooth. The worst stretch was a painful 23.73% drawdown that dragged on for about a year and a half from early 2018 to late 2019, which is where the strategy hurt most. The win rate is just under 49%, meaning nearly half the trades lost money, but the average winning trade was big enough to overcome the losers. The entry timing is a standout feature here, as the real entries beat 99% of random entry runs, so the signal itself is doing the heavy lifting rather than the exits. The edge also proved consistent, showing up in 3 out of 4 walk forward periods, so the result is not just a fluke from one lucky stretch.
