Bernard,

Joe has a point about what happens if there is an empty value.
Your code will be better if you use Nz() on the f variable.

Liste = CategoryGetSymbols( categoryWatchlist, 0 );
for( i = nb = 0; ( Sym = StrExtract( Liste, i ) ) != ""; i++ )
{
f = Nz( Foreign( Sym, "C" ) );
MMA = MA(f, 70);
nb = nb + (f> MMA);
}

Thanks for your help.
In fact there was an other error.
I was trying to find how many stocks on each bar had thei MA higher 
than their close.
So I have to declare  Nb as an array and increase by one each loop 
when the test is true.
With this modification it's works.

Thanks for your help.
