Here is what I get:
>>> ek.get_data( instruments = ['VINO.OQ'], fields = ["TR.SEDOL",'TR.SEDOLCODE', "TR.ISIN",'TR.ISINCODE'] )
( Instrument SEDOL SEDOL Code ISIN ISIN Code
0 VINO.OQ BNKLQX8 BP2TPL5 US36809R3057 US36809R3057
1 VINO.OQ BP2TPL5 , None)
The question is why I'm getting 2 records for 1 request.
