Time-series requests Datastream Web Service

Good evening

When downloading time-series data for multiple instruments using Datastream Web Serive in Python I get column names which contain the ticker (in this case ISIN) and field name (in this case P).

Whould it be possible to define similar to the the Datastream Add-in in Excel what the column header should be?

Thanks for your help.

ISIN is not a time series datatype. If you perform this within a snapshot request you can use the datatype ISIN

Please feel free to email directly james.bright@refinitiv if you would like to set up a call to discuss this in more detail.

Hi,

You can apply headers within Python. There are some examples here

Hi James,

Please find attached the output of the following request:

ds.get_data(tickers=['@AAPL','@FB'], fields=['DY'], start='-1Y', end='-0D', freq='D')

As you can see the header contains the ticker and the field name (

Best regards,

You can use the ISIN within your request to have this within the title.
