Bollinger Bands is a versatile tool combining moving averages and standard deviations and is one of the most popular technical analysis tools. There are three components to the Bollinger Band indicator:
Moving Average: By default, a 20-period simple moving average is used.
Upper Band: The upper band is usually 2 standard deviations (calculated from 20-periods of closing data) above the moving average.
Lower Band: The lower band is usually 2 standard deviations below the moving average.Onlinetradingconcepts
