I am trying to download price data for European options using the Eikon API. As an example, I have been trying to download data for options on Barclays stock. I cannot find the code I need to input to access the options on Barclays PLC, and have tried both BARC and some of the option tickers (e.g. BARC0721160C) for both the get_data and get_timeseries commands. Could you please let me know what these codes should be or where I can find them? It would be even better if there is a way I can download options data for the constituents of an index such as FTSE 100 or even a whole exchange?
The data I would like specifically is the daily closing price for each option.
