AFL- Needs help

["Brian Elijah" <cadvantag@xxxx>]

I was looking to find volatility or extreme tightness/contraction with the 
bands. This exploration returned no stocks
Basically I wanted yesterday to be the point of lowest distance between the 
bands over the past 10 days- How can I adjust this AFL.
Thanks in Advance,
Brian
