Using Moving Average Band Width to Read Volatility

Article MQL5 code base

Summary

Moving Average Bands Width (MABW) is described as a volatility indicator based on the percentage distance between moving average bands. Wider bands correspond to rising volatility, while narrower bands correspond to declining volatility. Changes in width may help flag a possible upcoming move or a shift in trend conditions.

The presented version marks exceptionally low band-width readings in red, treating extreme contraction as a possible sign of expansion after a congested period. The document cautions that the indicator does not indicate direction. It suggests using low extremes as context for potential trend changes or continuation after a range, rather than as a standalone buy or sell signal. The material briefly references an earlier published indicator description, but supplies no formula details, parameter settings, market examples, performance evidence, or validation of the proposed interpretations. Traders would need to test its behavior across instruments and timeframes before relying on it.

Key ideas

  • Moving Average Bands Width measures the percentage distance between moving average bands.
  • Increasing band width is interpreted as rising volatility, while decreasing width suggests falling volatility.
  • Extremely low readings may precede volatility expansion after a congested period.
  • The indicator describes volatility and does not provide directional signals.
  • Possible trend changes or continuation after a range are suggested interpretations, not validated results.
