What is a "universe" in the rdp.steamingPrices API for news headlines
streaming_prices = rdp.StreamingPrices(
universe = ['NFCP_UBMS'],
on_update = lambda streaming_price, instrument_name, fields :
display_news_headline(streaming_prices, instrument_name, fields)
)
So the code block above has a universe. And I'm not sure what it means and what values it takes in. Could someone help me out please?
Thank you!
Hi @bregarious,
The universe parameter in the rdp.StreamingPrices() refers to the list of instruments or RICs that provide real-time, streaming updates. In your case, you are specifying a streaming news headline RIC ('NFCP_UBMS') which will return headlines and some other metadata fields.
If you simply want to use the 'NFCP_UBMS' streaming RIC to retrieve streaming headlines, try this:
sp = rdp.StreamingPrices(universe = ['NFCP_UBMS'],
on_update = lambda streaming_price, instrument_name, fields :
print(f'Headline => {fields["HEADLINE1"]}'))
Hi,
Thank you for the answer. Is there any documentation on what values can be populated with the universe? And what data those values will provide?
Hi @bregarious,
The universe represents an identifier that describes what data you are looking for. If you want to understand what values you can use, I would start with the RIC Search utility: https://developers.refinitiv.com/en/tools-catalog/ric-search. You can find this link from the home page of the Developer Community. Additionally, you can navigate within your Refinitiv Workspace/Eikon desktop to discover the nature of the items you can use within the APIs. For example, typing in an expression such as "Apple" will pull up the RIC AAPL.O.
