    Standard Deviation Volatility is an indicator that measures volatility dispersion i.e. the difference between the actual price and the average price value. The indicator can be used to determine the strength of the market price movements. The stronger the price deviation from zero, the higher the volatility is. 

    StdDev = SQRT [SUM (Closen-1 - SMAn)^2)/N]
    StdDevVlt = StdDev/SMAn * 100

    where:
    SMA – n-period Simple Moving Average for current bar
    Close – close price for each of the past n periods
    N – calculation period
