RDP Data stops streaming overnight

Hello,

Does data stop streaming x hours after exchange close?

Around 8:40pm~ Sydney time I stop receiving ASX data for the RICs I have subscribed to (2500 RICs), even after next morning's market open.

I do not receive any status updates for these RICs in Closed state so I assumed data would continue streaming. As it stands, I probably need to have a cron schedule start the streaming process again. Is this correct? If so, when is the best time to do it for each exchange? ASX pre-opening takes place at 7am so my thought is sometime between 6:30am-7am.


Thank you.

    Hi @red

    Can you please confirm which API / Library you are using to consume the data?

    Are you connecting to the cloud-based Real-time Optimised service for the streaming data?

    Is this happening consistently every trading night or just sometimes?

    You should not need to restart the process every morning - as the data should continue streaming and you should get data in the morning.
    However, if you do decide to restart, then I recommend you contact the Content team at My.Refinitiv - so that a Content expert for ASX can confirm the best time to do so. The
    Refinitiv Real-time feeds carry over 80million RICs from 10,000+ sources - and
    we have Content specialists covering specific content sets.

    We are using the Java EMA SDK 

    "com.refinitiv.ema:ema:3.6.5.0"

    and are using the following service:

    ELEKTRON_DD

    It seems to be happening every night. I haven't run it enough times to say that with upmost confidence, but I will check tomorrow morning too and see if the same thing happens.

    New data simply isn't being sent to us. We are receiving new access tokens etc, but no new RIC update messages. I don't want to restart the service per se, but just re-request the RIC chain every morning (if this is the culprit).

    Hi @red

    As a test, are you able to enable low-level XML trace on your application overnight to see what is happening behind the scenes?

    How to enable tracing incoming/outgoing messages EMA Java receives/sends - Forum | Refinitiv Developer Community

    And if you can enable the API level logging as well - as described below, but set it to DEBUG?

    Clearly, this can generate much log output and may affect the performance of your application - but it could help understand why you are not seeing data in the morning.

    Please remove any credentials from the trace / log before uploading to the forum.
