Bollinger Band Reentry Strategy for Short-Term Long Trades

Summary

The strategy calculates a simple moving-average basis and upper and lower Bollinger Bands from a chosen price series. It enters a long position when price crosses upward through the lower band, then closes that position when price crosses downward through the upper band. The stated defaults are a 20-period lookback and a two-standard-deviation band width. This is a rule-based band reentry approach, although the document also characterizes it as trend tracking.

The published settings use BTC/USDT on Binance over a one-month period, with a three-hour chart interval and 15-minute base period. No performance statistics are supplied, so the settings alone do not establish profitability. The text notes that band signals can lag and generate false entries, especially in sideways markets, and suggests filters, adaptive parameters, and explicit risk limits. The described rules are long-only and contain no stop-loss or take-profit condition.

Key ideas

• The band basis is a simple moving average, with band width set by a multiple of price standard deviation.
• A long entry occurs when price crosses upward through the lower band.
• The position closes when price crosses downward through the upper band.
• The stated defaults are a 20-period length and a standard-deviation multiplier of two.
• The one-month BTC/USDT backtest settings include no performance results, and the rules specify no stop-loss.
