SFC java API processChainElementUpdate

David OL

We're using version 3.5.6-E7 of the SFC java API.

Our client extends com.reuters.sfc.realtime.chains.general.ChainElementRecordClient.

Recently we had some problems processing a ChainElementRecordClient#processChainElementUpdate(RecordChainElement) event which notified us of a RIC name change.

We get these messages approximately 4 times a year when our futures roll over to the next quarter.

Is there a test RIC that we can listen to that has regular name changes so we can test the behavior of our client without waiting until the next futures roll which takes place in December?

It was mentioned in the SFC Java developer guide.

Chain Element Updates
In statistical chains, such as .AV.L and .NG.O, the individual elements in the chain change over time.
...

I subscribed to .AT.PA (TOP 20 BY MOVES - Euronext Paris) and got the processChainElementUpdate events.

This event is not the RIC name change. It indicates an update of an element in the chain.
