Courses / Volatility and Volume Indicators

Bandwidth and %B

Two derived tools: how wide the bands are and where price sits inside them.

Bandwidth is the distance between the bands divided by the middle band. Low bandwidth shows a squeeze. %B shows where price sits relative to the bands: 1 at the upper band, 0 at the lower, 0.5 at the middle.

Low bandwidth readings relative to the recent past warn of a volatility expansion. %B helps to quantify overbought and oversold relative to the bands.

Use them to keep objective rather than guessing visually.

Key takeaways

  • Bandwidth shows squeezes
  • %B = position inside the bands
  • Objective readings beat guessing
