Hi Liftoff,

I see a problem with this
for(Slow; Slow<=MaxSlow;++Slow){
for(Fast; Fast<=MaxFast;++Fast){
vars Price = series(priceClose()),
Fast = series(SMA(Price,Fast)),
Slow = series(SMA(Price,Slow));
the variable Slow is in the for loop and then also in the series.
Same problem with Fast. Two of them need to be renamed.
P
