I have a IV/HV tool I use and curious how to create a scan using this. I would like to know when the HV is above the 80% level on a daily chart. Red line is above the top white line. Find stocks that meet that criteria.

Here is the tools code:

declare lower;

plot IV = ImpVolatility() ;
plot HV = HistoricalVolatility(30) ;
plot HVAnnualHigh = Highest(HV, 252) ;
plot HVAnnualLow = Lowest(HV, 252) ;
plot Level80Pct = HVAnnualLow + (((HVAnnualHigh – HVAnnualLow) / 5) * 4) ;
plot Level60Pct = HVAnnualLow + (((HVAnnualHigh – HVAnnualLow) / 5) * 3) ;
plot Level40Pct = HVAnnualLow + (((HVAnnualHigh – HVAnnualLow) / 5) * 2) ;
plot Level20Pct = HVAnnualLow + ((HVAnnualHigh – HVAnnualLow) / 5) ;

IV.SetDefaultColor(Color.RED);
HV.SetDefaultColor(Color.BLUE);
HVAnnualHigh.SetDefaultColor(Color.BLACK);
Level80Pct.SetDefaultColor(Color.white);
Level60Pct.SetDefaultColor(Color.white);
Level40Pct.SetDefaultColor(Color.white);
Level20Pct.SetDefaultColor(Color.white);
HVAnnualLow.SetDefaultColor(Color.black);

I updated the title of this question to better reflect the context.

You do not need any code to build this scan. You can simply use the condition wizard to build it within a few clicks of the mouse. Screenshots below shows the basic steps.

This helps me find stocks that are greater than 0.8 but I'm looking for the 80% level that is calculated this way: plot HVAnnualHigh = Highest(HV, 252) ; plot HVAnnualLow = Lowest(HV, 252) ; plot Level80Pct = HVAnnualLow + (((HVAnnualHigh – HVAnnualLow) / 5) * 4) ; Find stocks with an IV above that zone. I did mention HV in the first post but I need IV above the HV zone on the chart. Thanks

Ok, here is the scan for that:

def HV = HistoricalVolatility(30);
def HVAnnualHigh = Highest(HV, 252);
def HVAnnualLow = Lowest(HV, 252);
def Level80Pct = HVAnnualLow + (((HVAnnualHigh – HVAnnualLow) / 5) * 4);
plot scan = HV > Level80Pct;
