Finviz's "Volatility" Formula?

The Finviz Technical Screener has "Volatility" but doesn't say which formula it uses to calculate it. The popup says it "Represents average high/low trading range." This isn't enough to tell me which "volatility model" they're using in this indicator filter.

 

Click the "Any V" selector icon next to Volatility. The resulting dropdown menu allows you to select a percent range per week or per month (Your choice as to per week or per month) and the available selections vary from ... Over 3% ... to Over 15%.

 

What did they say when you asked them ?

They didn't say anything when I asked them. Did they respond to you at all when you asked them anything?

 

I asked them questions about other issues via email...they did not respond to my emails.
