Using PYDSWS to fetch time series data.
Hi,
I am trying to fetch the field EPS1UP (which is available as time series) for a list of Indian Stocks (for eg, RELI.NS, HDBK.NS, RLXO.NS etc.) from 2001-2023.
How do I fetch this using the datastream API (Im currently using PYDSWS) in python? Also, can I use RICs as the ticker symbol in PyDSWS.get_data() ?

PyDSWS is not the official Refinitiv Datastream WebService Python library. You may need to contact the creator of this library via GitHub to verify what the problem is.
I tested the request with DatastreamPy, the official Refintiv Datastream WebService Python library and the request works fine.
import DatastreamPy as DSWS
ds = DSWS.Datastream(username = username, password = password)
ds.get_data(tickers='<ALSC.BO^E18>,<BION.NS>',
fields=['EPS1UP'],start='2000-01-01')0

Hi @BlackBird,
Yes, you can use tickers in the get_data request for DSWS - just enclose these in the braces <>.
E.g:
>>> ds.get_data(tickers='<RLXO.NS>, <RELI.NS>, <HDBK.NS>', fields=['EPS1UP'], start='2001-01-01', end='2020-01-01', freq='M')
Instrument <RLXO.NS> <RELI.NS> <HDBK.NS>
Field EPS1UP EPS1UP EPS1UP

Hi @BlackBird,
Its best to reach out to Refinitiv content support to get answers on data availability. You can raise a ticket at my.refinitiv.com and directly interact with a content expert.

Sure, can you help with the first part of the question?...the api syntax is not working for start = "2000-01-01" format.

great thanks, that works. But getting the below issue after a couple of api calls
Is this an issue from refinitiv side or syntax?

Nothing wrong with the syntax, I think you might be requesting too much data or too frequently. It could also happen due to the timeout and bad network. Try pacing out the requests.
