If a firewall or network device is configured with the source IP information, please correct your configuration to use the entire range of eligible addresses.

New CME Globex Market Data Protocol
In Q3 2014, CME Group is introducing Market Data Platform (MDP) 3.0, a low latency and direct data access solution designed to improve customers' ability to process and act on real-time price information. The protocol production dates will be announced in future CME Globex and Market Data Notices.

Important Update: Based on customer feedback, MDP 3.0 is being updated with a new trade reporting functionality. This update will impact the message layouts and require a new template for trade messages only. Further information and specifications will be published in the CME Globex Notices and updated Client Impact Assessment by the end of the year. The new messaging will be available for testing in New Release in early Q2 2014. Customers should not develop to the current trade reporting messages, since it will be changed before the production launch; all other messaging and functionality will remain unchanged.

MDP 3.0 includes:

• Simple Binary Encoding (SBE); replaces the current FAST compression model
• FIX 5.0 (SP2) Market by Price messaging formats
• Event-driven market price and trade information
• Enhanced market state dissemination
• Increased timestamp granularity
• Trade identifier on both market data and order entry messages

The  client impact assessment,  functional specifications, and  message specifications provide detailed functionality and messaging information.

MDP 3.0 channels and functionality are currently available in New Release.

A new MDP 3.0 certification suite will be available in AutoCert+. Customer systems receiving market data via CME Globex must complete this mandatory certification.

Real Logic Ltd. and Informatica have collaborated to create open source tools that provide extensive support for Simple Binary Encoding (SBE), the messaging standard developed through The Financial Information Exchange (FIX) Trading Community. The SBE decoders will create an environment that can be used directly by customers or treated as a reference implementation that can be extended into custom solutions tailored to individual customer’s needs. The information and tool are open to the public under an Apache Public License and available  here.
