High volatility scan

[lostcoastsurf]

I was seeking to use a filter in a scan for stocks with high volatility and came across a scan with the following code:

def lowVol = (VolatilityStdDev(6) / VolatilityStdDev(100)) < 0.5;

But I'm not sure what this line would filter. Is the statement true if the volatility for the last 6 bars is less than 1/2 the volatility of the last 100 bars? Am I reading it right?

Standard deviation helps determine market volatility or the spread of asset prices from their average price. When prices move wildly, standard deviation is high, meaning an investment will be risky. Low standard deviation means prices are calm, so investments come with low risk

This scans for ratio of the 6bars to the 100bars to be less than 50%

def VSD6 = reference VolatilityStdDev(6) ;
def VSD100 = reference VolatilityStdDev(6) ;

def lowVol = (VolatilityStdDev(6) / VolatilityStdDev(100)) < 0.5;

Can someone please provide the code for HighVol?
