Long-Only Bollinger Band Breakouts with Persistence-Based Exits

Summary

This strategy enters a long position when the closing price crosses above the upper Bollinger Band. The bands use a moving average and a standard-deviation width; the stated defaults are a 20-period average and a multiplier of 1.9. While in a trade, it counts consecutive bars that close at or below the upper band and exits when that count reaches the tolerance setting, or when the low reaches the middle band. The short-entry logic is present but disabled in the supplied source.

The document discusses false breakouts, parameter sensitivity, the lack of overall drawdown controls, and the limitations of a one-directional system. It suggests trend filters, ATR-based stops, position controls, and adaptive parameters, but these are proposals rather than tested features. Although the narrative describes a five-minute strategy, the published backtest configuration uses daily periods for ETH/USDT futures. No performance statistics are supplied, so the material does not establish profitability or suitability across timeframes.

Key ideas

• A close crossing above the upper Bollinger Band triggers a long entry.
• The strategy exits after too many consecutive bars fail to close above the upper band or when price touches the middle band.
• Short trading is disabled in the supplied implementation.
• The narrative describes a five-minute system, while the published backtest settings specify daily periods.
• False breakouts, parameter sensitivity, and absent account-level drawdown controls are key limitations.
