Do you plan to add bid and ask columns to the get_timeseries() function? According to the docs, bid and ask are not in list of available fields currently.
For example, for this RIC - /APCJ271702500.U - there no Close price, but there are Bid Close and Ask Close as of 2017-10-26, both can be retrieved using RHistory() in Excel. How to get them using get_timeseries()?
It seems that there is .WithView("BID") in C# API for this purpose, but is there any Python equivalent?
