I am now looking for: Given the stock RIC, let's say I have ASML.AS, as a stock RIC. I am looking for Option chain RIC, which is ASMLATMIV.EX, or 0#ASML*.EX. I tried to use eikon API, ek.get_data for that but it wasn't functional for all of the RIC's. Is the API now capable of doing such for all stock RIC's? I can say at least ek.get_data function is not.
Also is eikon api be able to transform symbology bewteen RIC and Bloomber ID?
