Mean-Reversion DCA Buys Below a 200-Period Bollinger Band

Summary

This strategy combines fixed-dollar investing with a mean-reversion entry rule for BTC/USDT. It calculates Bollinger Bands on a selectable timeframe, using a 200-period EMA as the middle line and a two-standard-deviation envelope. When price crosses below the lower band, it buys a fixed dollar amount, with quantity set by dividing that amount by the current close. The supplied settings identify Binance futures and daily backtest bars, while the band timeframe defaults to four hours.

The document explains the intended benefits of systematic entries during pullbacks and lists risks including persistent trends, repeated buy signals that exhaust available capital, parameter overfitting, and volatile conditions. It proposes trend filters, multi-timeframe confirmation, volatility-based sizing, and profit taking near the mean as possible refinements. The material provides a rule description and configuration, but no performance results or quantified evidence. Its stated open and close dates constrain the investment window, and the strategy closes positions after the configured closing date; practical results may depend on execution and capital assumptions.

Key ideas

• The strategy buys a fixed dollar amount when price crosses below the lower Bollinger Band.
• The band center uses a 200-period EMA, with the upper and lower bands set two standard deviations away.
• A selectable timeframe determines the data used for the Bollinger Band calculation.
• Repeated signals can consume capital, and mean reversion may fail during sustained trends.
• Suggested refinements include trend filters, volatility-aware sizing, and taking profit as price returns toward the mean.
