Bollinger Middle-Line Crossovers with Percentage Exits

Summary

This strategy uses a Bollinger Band middle line, calculated as a moving average, as a crossover trigger. It opens a long when price crosses upward through the middle line and a short when it crosses downward, provided there is no open position. Exits are based on a percentage gain target or percentage loss threshold measured from the average entry price. The listed defaults are a 20-period band, multiplier of two, target of 0.5%, and stop-loss threshold of 95%.

The document frames the method as combining mean reversion and momentum, and suggests volume or volatility filters, parameter searches, and limiting trades by market regime. It notes that the moving average can lag and that countertrend shorts may fare poorly in rising markets. A one-week BTC/USDT futures test period is given, but no performance results appear. The very wide stated loss threshold and brief test window limit what can be inferred about risk control or general performance; the source also calculates exits from closing prices rather than showing separate stop orders.

Key ideas

• The strategy opens long or short positions when price crosses the Bollinger middle line in either direction.
• It closes positions at a percentage profit target or loss threshold relative to entry price.
• The listed defaults specify a 0.5% target and a 95% stop-loss threshold.
• The document identifies indicator lag and short trades during bull markets as risks.
• The listed one-week test has no reported results and provides limited evidence of robustness.
