One way is to set up a second database with just the tickers you want
Or
Put them into a different group, or market within the same database

Hi Steve,
the plugin ABtool has a function for deleting single
and multiple tickers from the AB database. Just move
those stocks to delete into a watchlist and use the following
AFL code which is taken from the ABtool/Functions.afl.
You can also select them using a condition like in your example.
You can then put the result into any desired watchlist by
rightclicking within the results window of Scan/Explore.
//---------------------------------------------------------
function DeleteStocksFromDB(iWL)
{ // stocks in the given watchlist are deleted
// from the database
count = 0;
ticker = xxWLtickerFirst(iWL);
while (ticker != "")
{
count++;
xxWinText("" + ticker + "\n");
xxDeleteStockFromDB(ticker); // deletes from DB
ticker = xxWLtickerNext(iWL);
}
xxWLclear(iWL);
if (count > 0)
{
xxViewRefresh();
xxWLrefresh();
}
}
//---------------------------------------------------------
In your code call this function for example like this:
DeleteStocksFromDB(32);
This deletes all stocks in watchlist 32 permanently from the DB
and of course also from the watchlist.
You can find the latest ABtool/Functions.afl file here:

You just need to #include it at top of your own script
and issue the DeleteStocksFromDB() function.
UM
