Bollinger Percent B Reversion (Python Version)

This approach fades price extremes beyond the Bollinger Bands using the Percent B indicator. Moves above the upper band or below the lower band suggest overextension.

When percent B is less than zero or greater than one, the system bets on a return to the middle of the band. An exit threshold closes trades once momentum normalizes.

Stops are placed at a fixed percentage from entry.
