Bollinger Band Reversals with Fixed-Percentage Stops

Article Strategy library · Author: ChaoZhang

Summary

This document describes a Bollinger Band entry method paired with a fixed-percentage stop. Bands are built around a simple moving average, with upper and lower limits set by a multiple of price standard deviation. The proposed entries buy when price crosses back above the lower band and sell short when it crosses below the upper band, treating a return from an outer band as a possible reversal. A stop is intended to close a position after an adverse move of a preset percentage.

The stated example settings use a 20-period band, a two-standard-deviation multiplier, and a one-percent stop, with BTC-USDT futures bars at five-minute intervals over November 15–22, 2023. No backtest performance or trade statistics are supplied. The text alternates between mean-reversion and trend-following interpretations, so its market rationale is not fully consistent. Band parameters and stop distance can change signal frequency and losses; the brief settings alone do not show that the approach is profitable or stable across instruments and market regimes.

Key ideas

  • The method buys a cross back above the lower Bollinger Band and shorts a cross below the upper band.
  • The bands use a moving-average center and standard-deviation offsets.
  • A fixed-percentage stop is intended to limit adverse movement after entry.
  • The example specifies a 20-period length, a multiplier of two, and a one-percent stop.
  • The document supplies backtest settings but no performance results, and its stated rationale mixes reversal and trend-following ideas.
