[amibroker] Re: Artificial ticker

["Mike" <sfclimbers@xxxxxxxxx>]

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.
