Bollinger Band Mean Reversion with Stacked Entries and Fixed Profit Targets

Summary

This long-only mean-reversion system buys when price crosses below the lower Bollinger Band, using defaults of 20 periods and two standard deviations. It permits up to two concurrent entries by default, sizes each from equity divided by the maximum trade count, and closes the position when its return reaches a fixed 6% target. The published backtest settings specify ETH/USDT futures over a stated date range with two-day bars, but the document reports no performance results.

The notes frame the approach as a way to seek rebounds from oversold conditions while scaling into falling prices. They caution that persistent downtrends can turn repeated entries into accumulating losses, and the strategy has no stop-loss. A fixed target may also cap gains in stronger rallies; equal allocation ignores volatility and signal quality, and stacked positions can share the same market exposure. Suggested improvements include adding a stop or trend filter and adapting targets or sizing to volatility, but these are proposals rather than tested findings.

Key ideas

• A close crossing below the lower Bollinger Band triggers a long entry when open trades are below the configured cap.
• The default configuration allows two trades, uses 20-period bands with two standard deviations, and targets a 6% gain.
• Trade quantity is based on equity divided by the maximum number of trades.
• The strategy has no stop-loss, leaving losses potentially open-ended during prolonged declines.
• Position stacking can increase correlated exposure instead of diversifying risk.
