[amibroker] How to use AddToComposite to save Highest values ??

["treliff" <treliff@xxxxxxxxx>]

I'm using the following scan in an effort to save the highest Volume 
of a small group of symbols in a composite ticker (in other words: 
within that group determine the symbol with the highest Volume and 
save that particular Volume value in the "V" field of ~MyIndex):

AddToComposite(0,"~MyIndex","V");
AddToComposite(IIf(V>Foreign("~MyIndex","V"),V-Foreign
("~MyIndex","V"),0),"~MyIndex","V");

My non-programmer step-by-step logic tells me this should work but 
the result is not the Highest volume but instead the SUM of all 
Volumes. 

Anybody knows what's wrong and/or a different scan to accomplish this?

Thanks in advance!!
