In the Bollinger Bandwidth indicator, two lines are plotted below the chart.
1 – Green line represents Bollinger Bandwidth
2 – Red line represents the Average
The Bollinger bands are a measure of volatility. Using standard deviation, they are displaced from the moving average line.
The Bollinger Bandwidth is the difference between the lower and upper bands divided by the middle band.
During periods of high volatility, the distance between the two bands will widen and the Bollinger Band Width will increase.
The Bollinger bandwidth above the moving average indicates an increase in volatility.
