Did you know you can delete the old tickers not trading still in bodh
freeway, just use Tidy-Trash. Old tickers that have not traded in past
7 days are removed from the database.
The best method I can suggest if you want to keep old tickers is to
store them in a separate group/watchlist or wherever so you can
exclude them in any scans.
