Bollinger Band Re-entry Signals Confirmed by Stochastic RSI Extremes

Summary

This indicator combines a failed Bollinger Band excursion with a Stochastic RSI extreme to flag possible short-term reversals. It uses a 20-period moving average and two standard deviations for the bands. Stochastic RSI applies a stochastic calculation to RSI, then smooths it into K and D lines. A bearish signal follows a prior close above the upper band when the current close returns inside and both prior oscillator lines were above 90; the bullish setup mirrors those conditions below the lower band, with both lines below 10.

The document presents the signals as potential mean-reversion warnings, especially in ranging markets, and suggests using trend context or nearby support and resistance to judge them. It also describes chart markers, optional band shading, and alert flags. Signals are based on closed bars. No performance tests or outcome data are provided, and the author cautions that these markers are not, by themselves, evidence of a trend reversal.

Key ideas

• A signal requires price to close back inside a Bollinger Band after the previous bar closed outside it.
• The prior Stochastic RSI K and D readings must both be overbought or oversold for a signal to appear.
• The bearish and bullish setups are symmetric re-entry patterns at the upper and lower bands.
• The document frames signals as short-term reversal warnings and recommends considering market structure and trend context.
• The signals are confirmed at bar close, and the document provides no performance evidence.
