Hi @raymondsk.wong

The latest versions of the Refinitiv Real-Time SDK - which includes EMA is available from RT-SDK Java Downloads (or Real-Time-SDK/Java at master · Refinitiv/Real-Time-SDK (github.com) )

The Refinitiv-API-Samples/Example.EMA.Java.ValueAddObjectsForEMA: Value-add objects for EMA (github.com) you mention is an older Example provided for educational purposes. It is on our list of rebranding priorities and should be rebranded to use the newer Refinitiv branded Real-Time SDK versions in the coming months.

Any new development work you do should be done using the latest version of the RT-SDK from the main download page. If you decide to utilise the ValueAdd example as the basis for any application, you should be able to make the minor modifications to the imports/classname/paths etc required to build the example using the latest RT-SDK .

The RT-SDK can consume/publish data from/to RTDS(formerly known as TREP).

Hello @raymondsk.wong

While my colleague has provided a clear explanation for you above, please note that RTSDK Java is also available in the Maven Central repository.

EMA Java

ETA Java

The older versions of the APIs (the old API and package names, versions 3.5.x and below) are also available in the Maven Repository too, but I highly suggest you use the latest version.
