Thomas,

You only need to run the formula once (use selected symbol option
from AA window on any symbol), then you can reference the symbol from
any _other_ script as applied against any number of symbols.

Or, if you are trying to include the code segment within some other
script applied to multiple symbols, what about wrapping the logic
inside an if condition such that it only gets executed the first time
(e.g. use a static variable to control the flow
http://www.amibroker.com/guide/afl/afl_view.php?id=263 )

...
if (StaticVarGet("ATCFlag") != 1) {
AddToComposite(...);
AddToComposite(...);
AddToComposite(...);
AddToComposite(...);
StaticVarSet("ATCFlag", 1);
}

I've never used statics, so double check the syntax above, and test
what happens when the variable is Null.
