Gary: And why is that please?
Second question, why the differences in the ROC periods? Does it matter
if they are the same?
Thanks for a little more explanation on
this point. New to me.

Salil,
Let me give you a head start so you don't grapple with the same pain I
did. To best emulate FT correlation make sure you use ROC comparisons,
not close.
correlation(ROC(somefund,5),ROC(somebenchmarkfund,5),126) or something
like this.

Friends,<span

1) Is there anything like FT Cor (Co-relation) in
AmiBroker ?
2) Is there any way to *prevent* refreshing the
Names of securities
when refreshing the database using
