Bollinger Band Reversals with Candle Body Contraction

Summary

This strategy pairs Bollinger Bands with a reversal candle pattern. It looks for a candle whose body is less than half the preceding candle's body, with the two candles changing direction, after the preceding close has moved outside a band. A smaller bullish candle after a decline beyond the lower band initiates a long; a smaller bearish candle after a rise above the upper band initiates a short. The bands use a 21-period moving average and a stated deviation multiplier of 2.1. The source also plots continuation markers for subsequent closes moving in the reversal direction, though entries are tied to the initial pattern.

The source specifies fixed profit and loss exit amounts and gives a BTC/USDT futures backtest setup using daily bars over about a year, with hourly base data. No performance statistics are included, so claims of profitability or reliable false-breakout filtering cannot be assessed. The pattern may miss reversals or enter on moves that continue beyond the band; outcomes can depend on instrument, timeframe, band settings, and execution assumptions.

Key ideas

• The setup combines a Bollinger Band excursion with a reversal candle whose body is less than half the prior candle's body.
• A bullish reversal pattern after a lower-band excursion triggers a long entry, while the mirrored upper-band pattern triggers a short.
• The source uses a 21-period band average and a deviation multiplier of 2.1.
• The strategy specifies fixed profit and loss exits, while later continuation markers do not themselves define new entries.
• The stated futures test period has no accompanying performance results, leaving profitability unverified.
