EMA Consumer and Refinitiv Real-Time Optimized

Paolo Parlapiano

Hi,

given an existing EMA C++ based application, can it be used to consume data from a cloud-based Refinitiv Real-Time Optimized solution?

Is it simply a matter of configuring the correct coordinates in EMA, or there are other aspects to be taken into account?

Any reference to the relevant documentation on this would be much appreciated.

Thank you

Best Regards,

Paolo

Hi @Paolo Parlapiano

As well as additional configuration, you will require a few extra lines of code for the initial connectivity related section.

Once a connection is established and successfully logged in, the actual requesting of data, processing of data etc is the same for RRTO as is it is for a Refinitiv Real-Time ADS (TREP ADS) server connection.

To get an idea of what would be involved, I recommend you compare the source code for some of the ADS examples with the RRTO examples e.g. 113_MP_SessionMgmt vs 100_MP_Streaming example.

You will note that whilst the registerClient() call, as well as OnRefreshMsg, OnUpdateMsg handlers etc are the same, there is additional code for populating the config with some of the additional command line parameters.

The README.txt files that accompany the examples provide some more detail on the parameters. Also, note the Proxy parameters are only required if your organisation uses a proxy server, and the Websocket stuff is only required if you want to (optionally) make use a Websocket transport rather than the default RSSL type.

You may also find the 450_MP_QueryServiceDiscovery interesting to refer to.

In addition to this, contrasting the EMA Quick Start - Connecting to Refinitiv Real-Time -- Optimized with EMA QuickStart (Deployed) will provide some more context.
