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
The Bollinger Bounce
The theory is that: Price tends to return to the middle of the bands. That's the whole idea behind the bounce.
The reason for a bounce is that: Bollinger bands act like dynamic support and resistance levels.
Some traders believe in that these bounces and the strategy is best used when the market is ranging.
Then
Bollinger Squeeze
Simply, when the bands squeeze together, it usually means that a break out is going to happen.
