There’s an upper band [2] that’s traditionally set to a 2nd standard deviation from the average. And finally, there’s a lower band [3] set to a 2nd standard deviation from the This is Bollinger bandwidth indicator: Bandwidth = high-low/main I have added lowest and highest of N periods to programmatically identify bulge and squeeze.
