the only prob I see is "the user" is > 5k strong and each will have his own
idea on this and that'll translate into yet another career for TJ. But then
everything he adds is that way. I'm sure our great leader will come up with
something spectacular - but then there's Jagow...
Just kidding Bob - don't richter on me..

Dingo,
Thats why i think the user should have the capability to have a "user
defined" benchmark..If one can create it with ATC,and its in the database
how would it be any different that choosing the S&P500???
Please excuse me if i am way off as I am just learning the program and am
basically a programming numnut.
Allan
