Newbie here: I'm working on a notebook which compares prices of equities listed on both the London Stock Exchange and Euronext Amsterdam. Currently I have a set of the names of such equities and a mapping of each of these names to their respective asset on both exchanges.
One such equity is for Galapagos NV (stored as
galapagos). When I call
prices(galapagos, '2020-1-1', '2020-1-30')
I get the following exception
ValueError: At least one valid asset id is required.
I suspect some equities aren't supported by
prices and this just happens to be one of them. Does anyone else have any idea why I can't get price data for Galapagos NV?
