Gordan,
Maybe I'm confused, I thought those plot shape statements were showing
buy and sell signals. It's those signals that I want to show up in the
AA window and my price window.
The reason I want this, is because I had a John Clayburg scan that
gave me some pretty good candidates. I got the scan off this forum.
My hard disk crashed 2 wks ago and I lost this scan. I have searched
and searched this forum high and low and I can't find it anywhere.
I thought maybe by modifing your formula might be the answer to my
predicament.
Regards,
Cordell
