Is there a method to find the equities listed on a particular exchange both active and delisted. The Eikon screener is not accurately fielding this as it's saying there are only 821 inactive equities listed on exchanges in the United States and only 718 with Delisted Quote Flag set to True. This obviously is not correct and i know the data exist in datastream, but as it's a REST api, the only way to retrieve the data is to directly call it by RIC or from a list.
Any help would be greatly appreciated as this is quite important.
