Bollinger Band Reentry Signals with Double Standard Deviation Bands

Article Strategy library · Author: ChaoZhang

Summary

This five-minute strategy uses Bollinger Bands with two deviation widths. It calculates a moving average basis, first and second upper and lower bands, and treats the wider bands as a visual guide to trend strength. The trading rules act on the narrower bands: go long when the close crosses back above the first lower band, and go short when it crosses back below the first upper band. An opposite signal closes the current position and can initiate the other direction.

The document gives parameter defaults for a 20-period basis and a multiplier of 2, plus published backtest settings for BTC/USDT futures covering March 2024. It reports no performance results, so they cannot establish profitability or the claimed improvement in trend judgment. The write-up identifies frequent trading costs, signal errors, weak handling of one-way trends, and the absence of a stop loss as risks. It suggests adding risk controls, tuning band parameters, and filtering range-bound conditions.

Key ideas

  • The strategy enters long after price crosses back above the first lower Bollinger Band.
  • It enters short after price crosses back below the first upper Bollinger Band.
  • The second pair of bands supplies a visual indication of trend strength rather than a separate entry signal.
  • Opposite signals close existing positions and may open a position in the other direction.
  • The document gives no performance results and flags transaction costs and missing stop-loss protection.
