We have a question about the TRB feed. Right now, we receive both D4 and TRB on the same session, how we can differentiate if a message is D4 or TRB besides the symbol name?
Right now, in each reuters msg, there is a "NameFlag" Attribute, we see "INR=D4" and "INR=TRB" respectively. But is there a better way to differentiate them rather than comparing symbol name? such as if they are different in other AttribInfo field?
Which Elektron API that you are using?
If you are using EMA Java API, you can get the service name of incoming OMM message from Elektron/TREP via .serviceName() attribute.
Example Code:
public void onRefreshMsg(RefreshMsg refreshMsg, OmmConsumerEvent event)
{
if (refreshMsg.hasName())
System.out.println("Item Name: " + refreshMsg.name());
if (refreshMsg.hasServiceName())
System.out.println("Service Name: " + refreshMsg.serviceName());
...
}
public void onUpdateMsg(UpdateMsg updateMsg, OmmConsumerEvent event)
{
if (updateMsg.hasName())
System.out.println("Item Name: " + updateMsg.name());
if (updateMsg.hasServiceName())
System.out.println("Service Name: " + updateMsg.serviceName());
....
}
Example Result:
Item Name: EUR= Service Name: ELEKTRON_DD ..... Fid: 22 Name: BID value: 1.2331 Fid: 393 Name: PRIMACT_1 value: 1.2331 Fid: 25 Name: ASK value: 1.2335 ....
