Bollinger Band Breakouts with ATR Trailing Stops

Summary

This long-only trend strategy enters when price closes above the upper Bollinger Band, aiming to capture continued upward movement after a volatility breakout. The bands use a configurable lookback, standard-deviation multiplier, and moving-average type. An ATR-based trailing stop is intended to adapt its distance to current volatility, while a close below the lower Bollinger Band is another stated exit condition. The document describes using 25% of account equity per trade and gives default band and stop parameters.

Published test settings specify BTC/USDT futures over a period from April 2024 to April 2025, but no return, drawdown, or trade statistics are included. The written explanation and code should be read carefully: the code submits a trailing exit on entry and separately checks the lower band, and it does not include the additional filters discussed as possible improvements. False breakouts, parameter sensitivity, exposure sizing, and poor fit for falling or range-bound markets remain concerns; the text recommends testing across markets before relying on the approach.

Key ideas

• A close above the upper Bollinger Band triggers a long entry intended to follow strong price moves.
• The described exits use an ATR-based trailing stop and a close below the lower band.
• The published BTC/USDT futures settings include a 25% equity allocation, but no backtest results are given.
• False breakouts, parameter sensitivity, and one-sided exposure are identified as risks.
• Volume confirmation, short entries, and volatility-based sizing are proposed as possible extensions.
