Why for some underlying I haven't an output without error for the following code ?
ek.get_data("NOKIA.HE",['OPTION'])
Out :
( Instrument OPTIONS
0 NOKIA.HE NaN,
[{'code': 251658244,
'col': 1,
'message': "Error: Field 'OPTIONS' was not found in response for the instrument 'NOKIA.HE'",
'row': 0}])
For the fifty underlying of .STOXX50E I have 13 underlying with this error.
