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
