How can I pull historical data using eikon in python

vuk.magdelinic

Here is the answer I got from customer support. I tried to pull the value using the same data item code in python3 but I get none for all of them. How should I get the data in python3 using eikon data api? One example ric is US240421348=.

Hi @vuk.magdelinic,

Not all historical data from RHistory is available through Python API. You can take a look at Data Item Browser in Eikon and see which fields support history and other supported parameters.

For this instrument, I can see that only daily yields are available through Python. Try something along these lines -

>>> df, err = ek.get_data('US240421348=', ['TR.BIDYIELD', 'TR.MIDYIELD', 'TR.ASKYIELD', 'TR.BIDYIELD.date'], {'SDate':'0', 'EDate':'-20', 'Frq': 'D', 'Points': 20})
>>> df
      Instrument  Bid Yield  Mid Yield  Ask Yield                  Date
0   US240421348=      1.045       1.03       1.02  2022-02-11T00:00:00Z
