Bollinger Band Breakouts with Trailing Stops for Trend Following

Summary

This strategy uses Bollinger Band crossings to take directional positions: a close crossing above the upper band triggers a long, while a cross below the lower band triggers a short. The bands are built from a moving average and a standard-deviation distance. It also specifies a stop and trailing exit, with entries allowed inside a configurable date window and position quantity tied to stated capital and leverage settings.

The document describes a BTC/USDT futures backtest spanning roughly a year, but reports no specific performance figures. Its discussion cautions that band breaks can mistake expanding ranges for durable trends, that tight trailing stops can be hit by ordinary price swings, and that limited testing can encourage overfitting. It also calls out transaction costs and slippage as factors to include when assessing results, and suggests broader market testing, trend filters, parameter checks, and position risk controls.

Key ideas

• A close crossing the upper Bollinger Band opens a long, while a crossing below the lower band opens a short.
• The bands use a moving average and a standard-deviation width, with configurable inputs.
• A fixed loss threshold and trailing exit are specified for both directions.
• The published test uses BTC/USDT futures over about a year, but supplies no numerical performance evidence.
• Range expansion, tight stops, limited testing, and omitted costs can undermine the strategy.
