Does Bollinger upper-band breakout actually work on MSFT? We tested it
We ran Bollinger upper-band breakout on MSFT through walk-forward testing and a 100-run random-entry gauntlet. 4 of 4 unseen periods positive. Beat 76 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, with an 88.66% total return, but the ride was lumpy. The worst stretch was a 16.33% drawdown that lasted from mid-2020 into early 2021, which is where the strategy hurt the most. With 40 trades and a win rate under 50%, the result is not driven by just a few big winners, but the average trade still made a solid 1.81%. The entry timing shows a real edge, beating 76% of random entry runs, meaning the way you get into the trade is carrying the result rather than the exits. The edge also appears consistent, as the strategy was profitable in all four walk-forward test periods, so the performance did not come from one lucky stretch.
