Bollinger Band Reversal Entries with Layered Exit Rules

Summary

This system uses Bollinger Bands for entries that can be read as reversal signals: a long follows a move back above the lower band, while a short follows a move back below the upper band. It describes three exit layers: a band-zone condition after a minimum number of bars, a close across the middle moving average after a later threshold, and a trailing exit after price reaches the opposite band area and then retraces. The default band length and deviation multiplier are 20 and 2, while the exit settings include bar thresholds and a retracement percentage.

The document gives rules and implementation details, but no backtest period or measured results. It explicitly notes that the strategy lacks a conventional stop loss, that band and exit parameters may be sensitive, and that symmetric long and short rules may not fit asymmetric markets. The source uses a two-times-risk-distance trailing trigger and points to ATR stops, signal filters, adaptive parameters, time filters, and position sizing as possible extensions. These are proposals, not validated improvements.

Key ideas

• A long signal follows a move back above the lower Bollinger Band, and a short signal follows a move back below the upper band.
• The first exit checks whether price enters an inner band zone after a configurable bar count.
• A later exit closes on a cross of the middle moving average.
• The trailing exit is triggered after price reaches the opposite band region and is subject to a retracement rule.
• The described system has no conventional stop loss, and the document reports no performance results.
