Bollinger Band Middle-Line Crossover Strategy

Summary

The document describes a Bollinger Band system built from a simple moving average of the selected price source and bands set a chosen number of standard deviations above and below it. Its written rules first associate contact with the upper band with a short and contact with the lower band with a long, then describe entries when price crosses the middle line: upward for long and downward for short. The supplied implementation follows the middle-line crossover rules and reverses between long and short positions; it does not implement the stated band-touch entries or specify take-profit or stop-loss orders.

The material presents the system as parameterized and easy to implement, and suggests tuning band settings, adding trend filters, and improving exits. It also acknowledges parameter sensitivity, missed trades, and potential losses when market conditions change. Published settings refer to BTC/USDT futures over a one-month period, but no measured results are included, so claims of positive performance or reliability are not supported by the evidence shown.

Key ideas

• The bands use a simple moving average and a standard deviation multiple around the selected price series.
• The written entry rules mix band-touch signals with middle-line crossovers.
• The supplied implementation enters long on an upward middle-line cross and short on a downward cross.
• The example code does not implement band-touch entries or explicit stop and profit exits.
• The stated backtest period is short and no performance statistics are reported.
