I have 2 questions:
1. I'm trying to fetch prices for few delisted RICs for eg APOL.OQ^B17 but I have the old RICs i.e APOL.OQ. Is there anyway to fetch the prices directly using the old ticker or convert the old RICs to new RICs (P.S. Have tried rdp.search('APOL.OQ') and ek.get_symbology, doesnt seem to work).
2. Can we generate a list of all stocks that existed in US markets (both listed and delisted as of now) and the RICs.
