Bollinger Band Re-entry Signals for Potential Reversals

Summary

This indicator uses Bollinger Bands to flag possible reversals after price moves outside a band and then closes back within it. A buy marker follows a close below the lower band and a subsequent close above it; a sell marker follows the inverse sequence at the upper band. It suppresses repeated signals in the same direction until an opposite signal appears. The bands can be shown or hidden, and users can adjust the period, deviation multiplier, and input price.

The document presents the signals as a technical-analysis aid, with particular relevance to ranging conditions where prices may revert from volatility extremes. It cautions that strong trends can produce countertrend signals and suggests adding a trend filter or other confirmation. Signals are said to be confirmed after candle close, but the document provides no historical test, comparison, or measured accuracy. It also gives no explicit entry, exit, or position-sizing rules, so the indicator alone is not a complete trading strategy.

Key ideas

• A buy signal appears when price closes back above the lower Bollinger Band after previously closing below it.
• A sell signal appears when price closes back below the upper band after previously closing above it.
• The indicator limits repeated markers in one direction until a signal in the opposite direction occurs.
• Its reversal logic may fit ranging markets, while trend filters may help address countertrend signals in strong trends.
• No test results or complete trade management rules are provided, so signal performance is unknown.
