Whether any of the RIC for the same company would return the same amount of historical news

Options

I noticed that each CUSIP would map to several RICs. I'm wondering whether each of the RIC for the same CUSIP would return the same amount of historical news. Thanks.

  • It looks like that, but I would still recommend to use the primary RIC:

    tr.get_symbology('037833100', from_symbol_type='CUSIP', to_symbol_type='RIC')

    or

    df, e = tr.get_data('037833100@CUSIP', ['TR.PrimaryRIC'])

    image

    Note that @CUSIP in the symbol is optional, can reduce ambiguity though.
