Volatility Intermediate

Bollinger Bands

A volatility indicator plotting bands a set number of standard deviations above and below a 20-period moving average. The bands widen in volatile periods and narrow in calm ones, and a narrowing squeeze often precedes a significant move. Developed by John Bollinger, they are taught as the bridge between statistical volatility and chart reading.
