Bollinger Band Touch Reversals with Middle-Band Exits

Summary

This document outlines a mean-reversion system that enters when price first touches or crosses an outer Bollinger Band. It uses a 20-period simple moving average for the center line and a 3.4 standard deviation multiplier for the bands. A low reaching the lower band prompts a long entry; a high reaching the upper band prompts a short entry. Positions are closed when price returns to the center line.

The text presents the bands as a way to combine price trend and volatility context, while acknowledging that a sustained move can continue beyond a band and generate losing reversal trades. It also flags parameter sensitivity, timeframe dependence, and slippage, and proposes trend filters, multiple timeframes, adaptive parameters, and stop management for further investigation. The published settings identify BTC USDT futures and a one-month date window, but give no performance metrics. There is also a discrepancy: the narrative says the strategy runs on five-minute bars, while the listed backtest period and base period are both five hours. The document does not resolve this mismatch.

Key ideas

• The system treats first touches of the outer Bollinger Bands as potential reversal entries.
• The center moving average serves as the stated exit level for both long and short trades.
• The setup uses a 20-period basis and a 3.4 standard deviation multiplier.
• Persistent trends can invalidate mean-reversion entries, while slippage may worsen outcomes.
• The described five-minute timeframe conflicts with the published five-hour test settings.
