Bollinger Band Breakouts with Optional Reversal Entries and Trailing Stops

Article Strategy library · Author: ChaoZhang

Summary

This strategy uses a weighted moving average as the Bollinger Band center, with upper and lower bands offset by a multiple of standard deviation. A price move above the upper band triggers a short entry, while a move below the lower band triggers a long entry. Traders can choose trend-style entries or reverse direction when price returns inside the bands. The setup also offers fixed or trailing stop-loss and take-profit orders, plus an optional time-of-day restriction for buying.

The document describes the rules and inputs, including a 20-period center, deviation of 2, and example stop and limit values. It provides no performance results, so the claims that the approach controls risk or captures trends are not demonstrated by backtest evidence here. It notes that abrupt reversals can trigger losses, while reversal entries can miss continued moves. Parameter choices may affect risk, and suggested additions include volatility-adaptive settings, volume or indicator filters, and trading-hour limits.

Key ideas

  • The center band is a weighted moving average, and the outer bands are based on standard deviation.
  • A break above the upper band enters short; a break below the lower band enters long.
  • An optional reversal mode enters in the opposite direction when price returns inside the bands.
  • Stops and profit targets can be fixed or trailing, with an optional time filter for buying.
  • The document gives no backtest performance evidence and identifies reversals and parameter selection as risks.
