Bollinger Band and Stochastic RSI Reversal Signals

Summary

This indicator combines Bollinger Bands with a smoothed Stochastic RSI to flag potential reversals. A bullish signal follows a close below the lower band when the next close returns above it and both Stochastic RSI lines are below the lower threshold. A bearish signal uses the corresponding move back below the upper band with both lines above the upper threshold. The documented defaults use 20 periods and two standard deviations for the bands, and thresholds of 10 and 90 for the oscillator.

The document includes a brief BTC/USDT futures backtest setup on Binance, using 15-minute bars over about a month in 2022, but supplies no readable performance results or discussion of costs. The source also maps bearish signals to long entries and bullish signals to short entries, which conflicts with the signal labels and warrants checking before use. The setup describes a possible reversal indicator, not evidence that the signals are profitable; results may depend on market, timeframe, parameter choices, and execution.

Key ideas

• The indicator combines Bollinger Band re-entry with extreme Stochastic RSI readings to identify possible reversals.
• A bullish signal requires a prior close below the lower band, a return above that band, and both smoothed oscillator lines below the lower threshold.
• A bearish signal applies the mirrored conditions around the upper band.
• The published backtest setup identifies a BTC/USDT futures market and timeframe but provides no legible performance evidence.
• The source code's entry directions appear opposite to the plotted bullish and bearish labels.
