The Mainland Market Data Hub (MMDH) is HKEX’s first infrastructure footprint in Mainland China and part of the implementation of the HKEX Orion Market Data Platform (OMD). OMD is deployed in Shanghai to establish the MMDH as the point of presence to facilitate local clients to easily gain access to HKEX market data. Dedicated International Ethernet Private Lines (IEPL) connect MMDH in Shanghai to HKEX OMD central system servers in Hong Kong, delivering market data of HKEX markets and indexes in a common message format.

MMDH provides a direct access solution to Mainland clients by providing a direct connection point established in Shanghai with lower line costs than direct cross-border leased lines that clients use to connect to Hong Kong.

The datafeed products currently offered include OMD Securities Standard (SS), Index Feed (Index), Odd Lot Order Feed (OLO) and Stock Connect Market Feed (SCM). Subject to market demand, HKEX may consider adding other datafeed products for the securities market as well as the derivatives market in the future.
