Bollinger Bands

Bollinger Bands

The Bollinger Bands are a technical analysis indicator developed by John Bollinger in the 1980s, used to measure market volatility and identify potential trading opportunities. The Bollinger Bands indicator is a powerful technical analysis tool that provides valuable insights into volatility, overbought/oversold conditions, and potential trend reversals.

This indicator consists of a central line, typically a simple moving average (SMA), and two outer bands representing standard deviations from the SMA.
