Terry,

reviewing my last posting and program it came to my mind to control 
the processing of the looop using a static-variable:

Filter = InWatchList( 4 );
if (NOT StaticVarGet( "firsttime"))
 {
 StaticVarSetText( "firsttime","1");
 List = CategoryGetSymbols( categoryWatchlist, 4 ); 
 for( n=0; (Ticker=StrExtract( List, n) ) != "" ; n++) 
  {
  //action here
  }
 }

cheers
enzo
