Hi Anthony,
Sorry for the vagueness!
What I found is that when I make a composite of ~Adv & ~Decl, THEN
do this calculation:
perc_Adv=Foreign("~Adv","x")/(Foreign("~Adv","x")+Foreign
("~Decl", "x") ) * 100;
..and add this calculation to another composite:
AddToComposite(Perc_Adv,"~Perc_Adv","C");
Then the value within "C" is (I think) the sum of the perc_Adv for
every stock on a day. Not just the single value.
The value is much greater then I expected.
Cheers Glenn
