Combining Bollinger Band Crossovers with RSI Extremes

Summary

This strategy combines Bollinger Bands with the Relative Strength Index (RSI) to generate entries. Its stated defaults use a 20-period simple moving average with bands two standard deviations away, alongside a 14-period RSI. A long signal occurs when price crosses upward through the lower band while RSI is below 30; a short signal occurs when price crosses downward through the upper band while RSI is above 70. The example plots the indicators and submits entries when those conditions occur.

The document frames the method as seeking reversals, but includes no market specification, backtest settings, or performance evidence. It warns that temporary band breaks can create false signals, countertrend entries can struggle in strong trends, and lag, parameter sensitivity, noise, and transaction costs can matter. Trend filters, volume confirmation, adaptive settings, stops, and multi-timeframe checks are proposed as possible refinements, without evidence that they improve results.

Key ideas

• The strategy combines Bollinger Bands with RSI overbought and oversold thresholds.
• A long entry follows an upward crossing of the lower band while RSI is below 30.
• A short entry follows a downward crossing of the upper band while RSI is above 70.
• The example plots indicators and submits long or short entries when the conditions occur.
• The document warns about false breaks, trending-market losses, lag, parameter sensitivity, noise, and trading costs.
