Then the Rate of Change of that moving average is taken, which represents an oscillator that measures volatility. A positive result indicates increasing volatility, whereas negative values signals decreasing volatility.

The Volatility (VOLA) indicator is a lower technical study. ProSticks uses the default parameter of 10 bars to calculate Volatility.
