Sjaak,
All you have to do in
http://groups.yahoo.com/group/amibroker/message/48903
described method refers to the
// 2. VEHICLE SELECTION
POPULATION=100;// set your database population here
NUM=Optimize("NUM",30,0,POPULATION,1);
list = GetCategorySymbols( categoryGroup, 254 );// move your database
to group254
symbol = StrExtract( list, NUM );
SetForeign(symbol);
C1=C;
Another version is
// 2. VEHICLE SELECTION
symbol="XXXXX";// write your index inside the ""
SetForeign(symbol);
C1=C;
It will use your index as trading vehicle.
The rest code is universal.
