Under OMM model, does MarketDataItemEvent can be triggered?

In RFAJ 7.5, we can get OMMItemEvent update message in callback function, processEvent(Event event).

Can MarketDataItemEvent update message be captured or triggered under OMM data model(RSSL connection type)?

I tested many times and found it seemed the MarketDataItemEvent couldn't be triggered with RSSL connection type when the callback function, processEvent(Event event), was invoked.

    Hi @yujin.xu11

    MarketDataItemEvent is part of the legacy MarketFeed / SSLED connection type interface.

    With RSSL type connection you are using OMM data format and therefore only the OMM related events will be triggered.

    Is there any particular reason why you want to capture MarketDataItemEvent rather than the OMM equivalents?

    Please see the following tutorial for a brief introduction Retrieving Level 1 MARKET PRICE Data

    Further information can be found in the RFA Java Developer Guide - a link to the online version.

    You should also have PDF copies as part of the RFA SDK download.

    Note from the above download page that we no longer support RFA v7.5. The oldest supported version is RFA v7.6 (which is around 4 years old) - but ideally, you should upgrade to v8.x
