Bollinger Band and MACD Conditions for Contrarian Reversals

Summary

K’s Reversal Indicator I combines a long-lookback Bollinger Band with MACD line crossovers to produce contrarian entry signals. A potential long occurs when price is unusually low relative to the band and MACD crosses above its signal line; a potential short uses the corresponding upper-band condition and downward crossover. The document recommends using the signals with an existing directional bias in range-bound markets.

The published settings specify the MACD and Bollinger inputs, and the backtest configuration identifies a BTC-USDT futures sample. However, no performance results are reported, and the provided source shows entries without a defined exit method. The document also warns that the indicator may perform poorly in some markets and can give false signals during trends. It offers no reliable method for identifying those false signals, so users must determine exits and assess market suitability independently before relying on the entries.

Key ideas

• The indicator pairs an outer Bollinger Band condition with a MACD crossover.
• Long and short signals are contrarian and depend on price extremes and crossover direction.
• The document recommends applying the signals in range-bound conditions with a directional bias.
• No broadly reliable exit rules are provided.
• Trending markets may produce false signals, and no validation results are given.
