Bollinger Band Breakouts Using One Standard Deviation

Summary

This breakout strategy uses a 55-period simple moving average as the Bollinger Band center and places the upper and lower bands one standard deviation from it. A close above the upper band produces a long signal, while a close below the lower band produces a short signal. The document presents the narrower-than-classic band width as a way to alter sensitivity and suggests that closing-price signals may filter some intrabar moves. The source also allows the input price series and standard deviation multiplier to be changed.

The published configuration is for one-minute BTC futures data over a one-week span, but the document reports no backtest results. It cautions that ranging markets can generate repeated signals, and that false breakouts, fees, and slippage may erode performance. The source notes that volume, RSI, and other confirmations are absent, and the written explanation’s claim that one deviation lowers risk is not supported with comparative evidence. Stops, additional filters, and parameter evaluation are proposed as possible improvements.

Key ideas

• The band center is a 55-period simple moving average with bands one standard deviation away by default.
• A close above the upper band signals long, while a close below the lower band signals short.
• The input price source and band multiplier can be adjusted.
• The approach does not include volume or momentum confirmation in its basic signal rules.
• Ranging conditions, false breakouts, fees, and slippage are identified as risks.
