Migration from EZD to Real Time Optimized: need some examples (if possible in C#)

Oleksandr Kocherha - aka Sasha

Hi, we have been using EZD and MRN consumer written in C++ for years, but someone told us that this service will be closed down forever on September 2021 so we have to migrate to a new technology: Refinitiv Real Time Optimized and we'll use Websocket APIs to get the news. We already have access to

Real Time Optimized trial that will expire shortly.

We have found an example here:

https://github.com/Refinitiv-API-Samples/Example.WebSocketAPI.CSharp.MRNWebSocketViewer#readme

BUT it is for TREP technology.

QUESTION: where can we find some C# examples for Refinitiv Real Time Optimized?

Other languages are acceptable (as a last chance), but C# would be much better for us.

We'd like to keep this solution as simple as possible. We just need to read the news and to replace EZD and MRN consumer written in C++ with something simple in C# that uses Websocket APIs/Real Time Optimized. Please, give me a link with C# examples for this.

Thanks in advance.

Hi @oleksandr.kocherha,

Take a look at the example: https://github.com/Refinitiv-API-Samples/Example.RDPLibrary.DotNet.MRNStoryConsumer. This uses the Refinitiv Data Library for .Net. In that example, it provides a couple of ways to use the API to retrieve MRN data. I would suggest you review the "Using RDP Content library to retrieve MRN Story" as it provides a very easy and intuitive interface. For other examples using this library, refer to the example package: 2.3.06-News-MRN.

Here are C# Websocket API examples that connect to the Refinitiv Data Platform and the Refinitiv Real Time services.

https://github.com/Refinitiv/websocket-api/tree/master/Applications/Examples/RDP/CSharp

These are basic examples. You can look at the MRN viewer above for MRN handling.

Hi again and thanks a lot for your help.

I have a Windows Server (>=2008) computer.
As far as I understand in order to use REFINITIV REAL-TIME TEST ENVIRONMENT
I have to follow this installation guide https://my.refinitiv.com/content/dam/myrefinitiv/products/10947/en/Technical/621395.pdf
QUESTION 1)I cannot just download the examples, change some URLs/passwords/IDs and start using them,
before using the examples I have to download and install some software on my Windows Server (>=2008) computer, is it true?

621395.pdf TELLS:
2.1 Install Package
Download the Refinitiv Real-Time Test Environment package from the MyRefinitiv product repository. After downloading the Refinitiv Real-
Time Test Environment package, unzip its contents to the /opt/refinitiv/SOFTWARE directory.................
......................................
2.4.3 Automatic Configuration for Windows
The install script file for the Windows configuration is called rrtteSetup.bat. Run the install script from a command prompt with administrator
privileges. The install script creates the configuration file (rrtte.cnf) in C:\Refinitiv\rrtte\config directory.
......................................

I tried to open
https://my.refinitiv.com/content/mytr/en/product/real-time-test-environment.html
and
https://my.refinitiv.com/content/mytr/en/downloadcenter/loadview.html.html

QUESTION 2)
but unfortunately I cannot find REFINITIV REAL-TIME TEST ENVIRONMENT installation package for Windows, could you help me providing a link?
In Search Downloads https://my.refinitiv.com/content/mytr/en/downloadcenter/loadview.html
what Product Family should I select?

Where do I find REFINITIV REAL-TIME TEST ENVIRONMENT installation package for Windows?

Thanks

I think that the document is for EZD.

For the Refinitiv Real-Time Optimized, you need a valid credential and Internet connection. The Refinitiv Real-Time Optimized is in the cloud environment.

For a credential, you need to have:

• Machine ID or username
• Password
• Client ID (Application key)

For more information, please refer to Getting Start with Refinitiv Data Platform.
