Bollinger Breakouts with Staged Position Changes

Summary

This document describes a Bollinger Band strategy that enters on an upside breakout and reduces exposure in stages as price moves back toward or below the bands. The written method uses a 20-period simple moving average and bands two standard deviations away. It proposes buying half a position after an upside break or a one-hour confirmation, trimming 10% on a return to the middle band, and trimming 50% after a sufficiently deep decline below the lower band. The approach combines breakout participation with partial profit-taking and position management.

A one-hour BTC/USDT futures backtest configuration is included, but no results are reported. The code also differs from the prose: its breakout threshold is 1% above the upper band rather than the stated 5%, and the partial reduction is triggered by a cross above the middle band, not a return to it from above. The document notes that fixed band settings, whipsaws, missed breakouts, and early reductions in strong trends are potential drawbacks; it recommends further testing and risk controls.

Key ideas

• The strategy uses a moving average and standard-deviation bands to define breakout and pullback reference levels.
• It proposes entering half a position on an upside breakout or a one-hour confirmation above the upper band.
• Staged reductions are intended to realize some gains while leaving part of the position open.
• The source's breakout threshold and middle-band reduction condition differ from the written description.
• The published BTC/USDT futures setup has no accompanying performance results.
