About OMM stream

OMM stream is used to subscribe to streaming items of any Domain Model (for example, MarketPrice, MarketByPrice...) exposed by the underlying WebSocket protocol of the Delivery Platform (formerly Refinitiv Data Platform).

OMM stream emits several events that can notify an application of the latest fields values in real-time.
