Thomas,

Since your code includes +Name() inside composite name, EVERYTIME you run this on watch list

with more than 100 symbols it creates MORE than 100 composites in one run.

So I repeat: you should add all composite symbols *before* you run backtest that
creates more than 100 composites at once.

Also you are code is missing one thing:

you MUST start composite name with ~ (tilde).

vlanschot,

does my simple cci code also crash on your computer ?
It even doesn't include any custom backtest code, it's just a very basic code.

As you know Tomasz, I've also experienced this behaviour when using
ATC in CBT. In my case I do NOT create more than 100 composites all
at once. I only create one by doing the following:

AddToComposite( Foreign("~~~EQUITY","C"), "~~~My_Equity", "C",
atcFlagDefaults | atcFlagEnableInPortfolio );
AddToComposite( Foreign("~~~EQUITY","L"), "~~~My_Equity", "L",
atcFlagDefaults | atcFlagEnableInPortfolio );

CategoryAddSymbol("~~~My_Equity", categoryGroup ,
250 );

eq = Foreign("~~~My_Equity", "C" );

Nevertheless, it crashes, unless I've pre-created it. This is the
reason why I am not(YET) using multiple cxomposites in CBT, although
I'd love to, if only for risk management purposes.
