How could I implement the formula in Python Data Eikon API?

I have the following formula:

=RHistory("CR.N","TRDPRC_1.Close; TRDPRC_1.Timestamp","START:01-Jan-2022 END:09-Nov-2022 ADJUSTED:YES INTERVAL:1D",,"TSREPEAT:NO CH:IN;Fd",C2)

How could transform it correctly to the Python Eikon Data APi code?

And one more question. Is there any chance to convert the prices into USD easily via Python in this case? I know that in the formula builder it is not possible not in RHISTORY.

I am asking not only for CR.N but in general for a lot of other RIC-codes as well.

Thanks!

@alekseenkova.marina,

There is no automatic means of currency conversion to USD. You will have to pull the timeseries data for the FX conversion yourself and apply the conversion factor in your code. Regarding adjusted parameter - please see the help for get_timeseries method.

Here is an example of getting data for a CAD instrument and the USD conversion rate:

ek.get_timeseries(['TD.TO', 'CAD='],  fields=['CLOSE'], corax='adjusted', start_date='2022-01-01T00:00:00', end_date='2022-11-09T00:00:00', interval='daily')

Hi @alekseenkova.marina,

There is no equivalent of RHistory in the Python API. Python provides a get_timeseries function which can provide OHLC bar data for different intervals, but the data set and history depth is limited.

Try something like:

>>> ek.get_timeseries('CR.N',  fields=['CLOSE'], start_date='2022-01-01T00:00:00', end_date='2022-11-09T00:00:00', interval='daily')

You can get more information on parameters like corex, normalize etc, by invoking help:

>>> help(ek.get_timeseries)

@Gurpreet, thank you for the answer!

In the formula you provided I do not see this parameter: ADJUSTED:YES

How could we add this to the ek.get_timeseries('CR.N', fields=['CLOSE'], start_date='2022-01-01T00:00:00', end_date='2022-11-09T00:00:00', interval='daily') ?

And what about currency conversion?

What is the difference between ek.get_timeseries and rd.get_data for time series retrieval?

thank you!

Do I understand you correct that you advise me to use get_timeseries for fx rate retrieval as well?
