[amibroker] Re: Add addtocompiste generated ticker to a watchlist

["Bruce" <brucer@xxxxxxxxx>]

TA -

I have to go out, so let me see if I can explain quickly.

1. The AFL will add all symbols from group 253 that satisfy the condition.  You only need to use the current symbol because the symbol loop is built into the AFL.  If you want to run it again group 253, you would set the Apply To to Use Filter and the group to 253.  If you did that, AA is looping through the symbols for you and you would only need -

if ( StrLeft( Name( ), 1 ) == "~" AND 
  StrLeft( Name( ), 3 ) != "~~~" )
{
  CategoryAddSymbol( Name( ), catgorywatchlist, 61 );
}


2. See above for how to code what you expressed -

"I had the following two conditions is that all my composite tickers have one "~" as the first character in their symbol.  I also want to exclude all equity tickers that have "~~~" as the first three characters in their symbols."

Note - this will process anything that begins with "~" including for example, "~ABC".  This may or may not be what you want.
