Hi @otto.to

If you want the full market by price order book, just change the Domain in the Req from MarketPrice to MarketByPrice.

The exact Enum you will have to use may vary slightly depending on which API you are using e.g.

if you are using EMA Java it would be something like:

EmaFactory.createReqMsg().domainType(EmaRdm.MMT_MARKET_BY_PRICE)              .serviceName("DIRECT_FEED").name("AAO.V"), appClient, 0)

for EMA C++ it would be something like:

consumer.registerClient( ReqMsg().domainType( MMT_MARKET_BY_PRICE ).serviceName( "DIRECT_FEED" ).name( "AAO.V" ), client );

Please refer to EMA Consumer example 140 which is included with both EMA Java and C++ - which request MarketByOrder rather than MarketbyPrice - but the principle is the same.

You may also find the intro part of the following article useful.

How to Sort & Process Level 2 Orderbook Data using EMA C++ API | Refinitiv Developers

You should also reference the RDMUsageGuide.pdf which is provided with both of the above SDKs - for details on the definition and structure of the MarketByPrice domain.

Having said all of the above, if you are only interested in top of order book and / or data in a standard MarketPrice instrument, then I recommend you contact the Content Helpdesk at My.Refinitiv who should be able to advise on the exact RICs you require.

Thanks. I think this should work.

But how about legacy level 2?
