Market data is organized by Market Data Group, which is a configuration of MDP channels providing all market data required to support markets for a given product or set of products.
UDP Feed A and UDP Feed B are used to disseminate CME Group incremental market data using bandwidth efficient, compact encoded packets containing FIX market data messages. All packets are sent through both UDP Feed A and UDP Feed B applicable Market Data Groups. This redundancy minimizes the chance of message loss due to UDP.
Market data services provide the external data required to process CME Group market data.
