Hi,
I got an error message on this particular line, saying that the condition
has to be numeric or boolean. This is why I replaced == by =.
Here is what I have as a code:
arsignal = IIf( C>MA (C,20), 1,0);
arnotrade = IIf(HHV(arsignal,5)==1, 1, 0);
if (arnotrade==1)
{
//don't ACT on Buy/Sell Signals
// probably still want to calculate them
}
else
{
// code here for ACTING on your Buy/Sell signals
}
I'm still not sure what to write on the two particular line. Could you
please give me an example?
Thanks,
Louis
