mp,
I can see a number of issues here, which you may or may not be aware of.
1. You're combining static variables with non-static ones (ie.
StaticVerSet with VarGet). I don't know if this is supposed to work or
not, although your second example seems to indicate it does, but is
there any reason not to use StaticVarGet?
2. Your test condition "Buy OR sigScaleIn" will always be true for
every bar. "sigScaleIn" is a non-zero constant, not a variable, so it
doesn't matter what Buy is, that expression will always be true.
3. DateNum returns an array not a single value, so I'm not sure what
"sig.Symbol+DateNum()" is supposed to look like. With a quick test, I
notice it doesn't give an error but the appended string always seems
to be the same date, which for some reason is two days after today's date.
I don't think you can create multiple static variables at once using
array-style arithmetic. I think you have to use a loop (could be wrong
though). So to get what you want, try something like:
dn = DateNum();
for (i = 0; i < BarCount; i++)
{
if (Buy[i]) // Will include sigScaleIn
StaticVarSet(Name()+dn[i], longTriggerLevel[i]);
}
Then in the custom backtest procedure:
dn = DateNum(); // Before for loop over bars
....
eval = StaticVarGet(sig.Symbol+dn[i]);
Note that I haven't tried this though, so it may not work.
Regards,
GP
