HKEX Orion Market Data Platform (OMD) 

The HKEX Orion Market Data Platform (OMD) is an integrated low-latency platform delivering market data for all asset classes traded on HKEX markets in a common message format. It provides a suite of market data product feeds with content, market depth and bandwidth requirements tailored to suit the needs of different types of clients while delivering vital pricing data to subscribers rapidly and efficiently. It also enables HKEX to establish points of presence for market data distribution outside of Hong Kong, such as on Mainland China.

OMD will eventually become the unique ticker plant for market data dissemination following the decommissioning of the legacy trading devices (i.e. OG of the securities market and NG of the derivatives market) in order to maximise the processing efficiency of the trading systems.  By that time, clients may choose to receive market data directly from OMD or indirectly via information vendors.
