Dual Bollinger Bands for Long-Only Pullback Entries

Summary

The document presents a long-only strategy with selectable simple and augmented Bollinger Bands. The simple version uses a simple moving average of closing prices as its middle band; the augmented version uses exponential averages of closes, highs, and lows. Both use a standard-deviation adjustment to form their bands. A long entry is triggered when the chosen entry price reaches or falls below the lower band, subject to a maximum band-spread threshold. Exits target either the middle or upper band, with a fixed-percentage stop and an optional trailing stop. A setting can defer profit-taking until the position is profitable.

The strategy description frames narrow band spread as favorable for trend-following, but gives no empirical support for that interpretation, and its entry near the lower band resembles a pullback rule. The published test uses BTC-USDT futures on hourly bars for about a month and reports no results. The source also contains a date filter that is hard-coded to remain true, so the stated date controls may not function as expected. Parameter tuning and added filters are suggested, but profitability and transferability remain unproven.

Key ideas

• The simple and augmented band variants use different moving-average calculations for their central and outer bands.
• A long entry occurs at or below the selected lower band when band spread is within its configured limit.
• Exits can target the middle or upper band, with fixed and optional trailing stop mechanisms.
• The document proposes band width as a trend condition but does not provide evidence validating that interpretation.
• The short backtest setup provides no performance results, and the source date filter is hard-coded true.
