I am trying to convert Bloomberg tickers to RIC's. I will be doing to conversion in python. I have seen that get.data() and get.symbology() are the methods other people are using. But under what API and library do those exist?
There's no mapping between Bloomberg and Thomson Reuters symbology. The symbology you can use in Eikon includes Thomson Reuters RICs and PermIDs, stock (aka exchange) tickers, security identifiers such as ISINs, Cusips, Sedols, Wertpapierkennnummers, Valorens and numerous other local security identifier schemes. But it does not include Bloomberg symbols.
So it is possible to convert Bloomberg tickers to RIC tickers, you have to first convert your Bloomberg tickers to ISIN tickers using =BDP("ticker", "ID_ISIN") in excel. Then take that new list and use eikon.get_symbology() to convert these tickers into RIC tickers.
