Bollinger bands - Bollinger bands, named after their founder John Bollinger, have been a popular method of technical analysis for several years. They measure the support for, and resistance to price changes of any particular stock, by plotting the standard deviation of the moving average of a price.The longer a period of low volatility, the closer the bands are together, and the more likely it is that there will be a price breakout from the established price pattern.
