Hi @Ionut T

The Batch handle is automatically closed by EMA once it makes the batch request - as each item has its own individual handle & stream established by the API - since each item is updated individually and therefore needs its own stream.

If you want to close the individual items you can extract the handle from the OmmConsumerEvent that you receive in your event handlers e.g.

void AppClient::onUpdateMsg( const UpdateMsg& updateMsg, const OmmConsumerEvent& ommEvent )
{
...
    _pOmmConsumer->unregister( ommEvent.getHandle() );
...
}

If you want to unregister all items you need to get hold of the Login handle as demonstrated in example 333__Login__Streaming__DomainRep

You can then unregister the Login handle - which will close all items and log you out from the server as well.
