I am trying to get data for a benchmark curve (say 0#GBBMK=) so I'm using:
df, e = ek.get_data(['0#GBBMK='], ['MATUR_DATE', 'COUPN_RATE', 'RT_YIELD_1'] )
which gives me the most recent data for the curve.
How do I get the same curve for a different date? I have tried using Sdate and Edate, but I couldn't get it to work. Thanks.
