Domain Models for exchange

manucharfinalsi

The document enumtype.def has a list of exchanges in the world.

Question:

Refinitiv has Domain Model:

MarketPrice

MarketByPrice

MarketByOrder

Are these standard domain models appropriate for the entire list of exchanges that are in the enumtype.def document?

Are these three domain models standard for all market participants?

Hi @manucharfinalsi

The Domain models are exchange agnostic. As far as the specific models, the MarketPrice model will be available globally for all exchanges supported. The level2 models (MarketByPrice/MarketByOrder) are not available for every exchange - this is dependent on whether the exchange supports level 2 data or whether we have built the feed handlers to support level2 data for that exchange.

Please help to understand.

Exchange-Refinitiv Data Feed Direct

When exchange data goes to Refinitiv Data Feed Direct, is that real-time data converted to Domain Model MarketPrice and MarketByPrice (if the exchange supports Level 2)?

After converting the real-time data in accordance with the Domain Model, this data is broadcasted to the Cosumer?

Or does the exchange immediately give the real-time data in accordance with Refinitiv Domain Model?

Hi @manucharfinalsi

Yes, the Data Feed Direct will normalize the content from the exchange into our domain models, i.e. MarketPrice.
