Bollinger Band Entries with ATR Trailing Stops

Summary

This strategy pairs Bollinger Band price crossings with an ATR-based trailing stop. Using the stated defaults of a twenty-period band, a two-standard-deviation width, and a fourteen-period ATR multiplied by three, it enters long when price crosses upward through the lower band and enters short when price crosses downward through the upper band. While a position is open, the stop is updated from the close and ATR; the long stop can only move upward, and the short stop can only move downward. A crossing of the relevant stop closes the position.

The document frames these entries as a way to seek opportunities while the trailing stop adapts to volatility and can retain gains during favorable moves. It also warns of repeated false signals in ranging markets, slippage during sharp moves, and sensitivity to parameter choices, and suggests filters and volatility-aware position sizing. The specified backtest uses BTC/USDT futures on hourly data for about a month, but no outcome or performance statistics are given. The described rules therefore do not establish effectiveness across instruments or market regimes.

Key ideas

• A long entry follows an upward crossing of the lower Bollinger Band, while a short entry follows a downward crossing of the upper band.
• The example uses a twenty-period band with a two-standard-deviation width and a fourteen-period ATR multiplied by three.
• Trailing stops are intended to move in the favorable direction as the trade develops.
• The document identifies false breakouts, slippage, and parameter sensitivity as risks.
• Backtest settings are listed, but performance results are absent.
