Hello @y.attar

Do you want to contribute data to your local ATS or to the Real-Time platform with RCC?

Based on the give log, you are using the tunnel stream feature (which is required when connecting to RCC directly) and try to post data to a service name "ATS".

Please be informed that the API can connect to the ATS server via local RTDS directly without using the tunnel stream. The tunnel stream is for connecting to RCC only.

If you want to post data to your local ATS, there are the following resources that might help you.

The suggest EMA example for the ATS posting are as follows:

Hi @y.attar,

Are you sure you are using TREP for contributions to Contribution Channel? This step requires additional configuration within TREP as described within this article.

For Contribution Channel, the service name is DDS_TRCE typically. Service name ATS is typically used for contributing to local ATS and not contribution channel.

Also, for EMA, you can directly contribute the data to contribution channel without using RTMDS (TREP). See this tutorial for an example.

Hi @Gurpreet, Thank you for this explanation, this is clarify the confusion around the contribution model that we're looking to implement as initially the question concerned ATS as local contribution.

Hello @wasin.w

Thank you for your help and in fact after review EMA API documentation/example (Implementing Refinitiv Real-Time API applications to work with ATS - Part 1 & Implementing Refinitiv Real-Time API applications to work with ATS - Part 2 ), just yesterday I have tested with success to connected/Publish on ATS via API example 341_MP_OffStreamPost.

Thanks again,

Younes
