Good afternoon!
I am new to Eikon Data API and Codebook. In my Codebook I download historical fundamental data for some companies (Revenue, EBITDA etc.). For instance, I want to get Revenue over 3 last years for some ric.
So I should write a query like:
df, err = eikon.get_data(ric, [{'Tr.Revenue': {'params': {'year': 'FY2019', 'curncy': 'USD'} } },
{'Tr.Revenue': {'params': {'year': 'FY2018', 'curncy': 'USD'} } },
{'Tr.Revenue': {'params': {'year': 'FY2017', 'curncy': 'USD'} } }])The question is, how can I pass multiple parameter values in one query. In the example above I makein fact 3 queries, which seems to be rather unefficient. I would like to do something like:
df, err = eikon.get_data(ric, {'Tr.Revenue': {'params': {'year': ['FY2019',
'FY2018',
'FY2017'],
'curncy': 'USD'} } })I have written some custom function in Python to do that. May be I don't know something and there is built-in method to pass multiple values for parameter in query?
P. S. Parameter names in get_data and DIB do not match. For example, in DIB (Data Item Builder) I see 'Currency', and in get_data I shall write 'Curncy'. Where can I find parameter names exactly for get_data() function ( help(eikon.get_data() is useless )?
