We have 2 accounts: Eikon and Realtime feed. We use RFA C++ API for the second.
We have access to some data in Eikon, that is not permitted in RFA. How can I check that the data from Eikon will be available in RFA API before we pay for new data?
RFA C++ is designed for consuming real-time streaming data (as well as TimeSeries one data and ANSI pages).
Eikon allows you to consume a much broader range of data sources and content types.
Please speak to your Refinitiv Account team to discuss in more detail, what data you want to consume using RFA C++ - they should be able to advise you / put you in touch with a content specialist who can advise further.
Please note that if you are writing a new application to consume streaming data, I would strongly advise you to use our strategic Enterprise Message API instead (RFA is feature-complete and will not be enhanced with any new features).
If the purpose of your new development is to migrate from Desktop to Server implementation, much of the non-realtime data available in Eikon is also available via our Refinitiv Data Platform using Restful RDP APIs (or helper libraries in Python, .NET and Typescript). Your Refinitiv Account team should be able to advise further and/or arrange a free RDP Trial so you can explore the content yourself.
