[EquisMetaStock Group] Re: StochRSI

[gapupgoat <no_reply@xxxxxxxxxxxxxxx>]

I have to say, Roy, that you have an amazing talent. May great health
rain down on you in the New Year if it hasn't already. That was
probably simple to you but I've been working on it for a while. And
great thanks to Preston, also. And by the way, is there a forum.doc
explaining all of the additional functions in the latest forumdll
collection? I can't find anything but the old one in the file section.
Thanks again. Rick.
