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.

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.

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.

MDP 3.0 Decoder
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.

New Strip User-Defined Spread for Energy Options
Effective Sunday, June 1 (trade date Monday, June 2), a new option strip User-Defined Spread type (tag 762-SecuritySubType=SA) will be introduced on CME Globex for NYMEX energy markets.

The SA option strip spread is constructed of all calls (Call Strip) or all puts (Put Strip). The Call Strip consists of buying calls within the same instrument and strike price for up to 26 expiration months, resulting in a total of between two and 26 calls purchased. The Put Strip consists of buying puts within the same instrument and strike price for up to 26 expiration months, resulting in a total of between two and 26 puts purchased. The Strip requires all legs to be equally distributed maturities (e.g., M8-U8-Z8 or M8-N8-Q8).

An SA spread trade price is the average of the outright leg prices. The trade reports for both the spread and the outright legs will reflect the averaged price.

Only one strip UDS type will be supported per options market. With this launch, the current option strip UDS (tag 762-SecuritySubType=SR) will be retired in the NYMEX energy options markets. The SR type will continue to be supported in all other options markets on CME Globex.

A detailed description of Option Strip spread types is available  online.

The new spread type is now available in Certification for customer testing.

User-Defined Spreads for Energy Futures
Effective Sunday, June 8 (trade date Monday, June 9), CME Globex will launch User-Defined Spreads (UDS) for energy futures. UDS allows traders to create the precise spreads they wish to trade in real time. UDS for futures will be supported alongside exchange-defined futures spreads.

The CL and NG product groups (FIX/FAST tag 55-Symbol or MDP 3.0 tag 1151-SecurityGroup) will not support UDS for futures.

UDS for futures is an extension of the current UDS for options functionality. It has been designed to reduce customer impact by mimicking existing functionality and messaging. Certification is not required if customer systems have already certified for UDS for options.

A  client impact assessment is available now with detailed messaging and functionality specifications.

UDS for futures is now available for customer testing in Certification and New Release.

 Consolidated CME Globex and Market Data Notice

iLink Session ID Auto-Deletion Process
On Monday, May 5, CME Group executed our iLink session ID auto-delete process. All iLink sessions must meet a minimum messaging threshold of 100 messages over three months to exempt themselves from this process. Any iLink session ID with fewer than 100 messages will be flagged for deletion. For the purposes of this policy, a message is defined as a new order (tag 35-MsgType=D), order cancel/replace request (tag 35=G), order cancel request (tag 35=F), and mass quote (tag 35=i).

Idle iLink session IDs needlessly consume resources and make load balancing and resource allocation planning more difficult. CME Group is committed to managing session IDs to ensure the best performance on CME Globex for our customers. The iLink session ID auto-delete process helps ensure these resources are managed proactively and consistently across the marketplace.

An e-mail notification was distributed to clearing firms and execution firms with Firm Admin Dashboard access on Monday, May 5. Clearing firms will have four weeks to review their idle session IDs. One week before the deletion, Friday, May 30, CME Group will change the passwords and shut the ports for idle iLink session IDs. All idle session IDs will be deleted at the end of the day on Friday, June 6. Details on the process are available  online.
