Bollinger Bands

Bollinger Bands are yet another technical indicator. Yes, there are thousands of them. This one is named after its inventor and indicates a range for the price of a financial security. It consists of three parts:

  1. A Simple Moving Average.
  2. An upper band of two standard deviations above this moving average—the standard deviation is derived from the same data with which the moving average is calculated.
  3. A lower band of two standard deviations below the moving average.
