Critical System Updates

UpdateUpdate - Price Precision Extension - 2018

† Denotes update to the article

†This weekend, the fourth set of production MDP 3.0 channels will be updated to the new schema version 9:

†Channel Number	†Name	†Market Segment	†Production Launch

311	CME Globex Equity Options	54	October 21, 2018
312	CME Globex Interest Rate Futures	82	October 21, 2018

200	CME Credit OTC (OTC Daily)	Streamlined	October 21, 2018
201	CME Cleared OTC (OTC Daily)	Streamlined	October 21, 2018

CME Group is implementing end-to-end technology changes to support increased price granularity. Currently, CME Group systems support a maximum of 7 decimals. With this initiative, products with up to 9 decimals may be listed and traded. On Sunday, January 13, 2019 (trade date Monday, January 14), pending regulatory approval, the 2-Year Treasury Note futures, all 2-Year Treasury Future Spreads (including Calendar Spreads, Tail Spreads and Inter-Commodity Spreads with a 2-Year Treasury Future) along with the futures portion of covered options UDS, will move from 7 decimals to 8 to support trading at 1/8 of 1/32.

Customers are encouraged to move to support 9 decimals now; but there are no plans to list a product that uses the 9th decimal at this time.

With this release, customer certification will be required for MDP 3.0 and Streamlined SBE.  The new Market Data templates are currently available in New Release and the AutoCert+ test suite is now available for certification.

On Sunday, November 18, a production test instrument for the 2-Year Treasury Note futures will be launched on CME Globex. This new test instrument will give customers the ability to confirm system readiness for the introduction of 8-digit decimal price precision. Upon the launch of this test instrument, clients whose systems are not yet prepared to handle 8 decimal precision must ensure their systems have the ability to ignore market data and iLink/Drop Copy execution reports on this new instrument.

Automated Port Closure for Drop Copy Sessions - November 18

Effective Sunday, November 18 (trade date Monday, November 19), CME Globex will implement Automated Port Closure on Drop Copy sessions to further protect CME Group markets and systems from potentially detrimental behavior. Currently, CME Globex Port Closure Policy applies only to iLink sessions.

With this implementation, CME Globex will automatically logout and close both the primary and backup ports for any Drop Copy session that exceeds 5 invalid Logon (tag 35=A) messages in 60 seconds. Logon messages may be invalid due to:

• Incorrect sequence number
• Invalid heartbeat interval
• Malformed message
• Required tag missing or sent with invalid value
• Invalid SenderCompID (tag 49)

Automated Port Closure on Drop Copy sessions can also be triggered by sending messages other than a Logon when the session has not yet been successfully logged in and by exceeding the Administrative Messaging Threshholds.

When triggered, the Drop Copy gateway will send a Logout message (tag 35=5) with tag 58-Text="(1000) CME Administered Port Closure Due to Invalid Number of Login Attempts Being Exceeded".

Sessions with active-active fault tolerance will receive the Logout message on both the primary and backup instances. Sessions without fault tolerance will only receive the Logout on the primary instance, but both the primary and backup ports will be closed.

An authorized Drop Copy contact must contact the Global Command Center directly to have a port re-opened. The GCC can be reached in U.S. at U.S. at +1 800 438 8616, in Europe at +44 20 7623 4747 or in Asia at +65 6532 5010.

Automated Port Closure for Drop Copy is currently available for customer testing in New Release. To facilitate customer testing, the parameters in New Release will be 5 invalid Logon (tag 35=A) messages in 15 seconds.

Messaging Controls for Drop Copy Sessions - November 18

Effective Sunday, November 18 (trade date Monday, November 19), Drop Copy sessions will be subject to Administrative Messaging Thresholds. The following administrative messaging thresholds will apply.

Messaging Controls for Drop Copy Sessions
Environment	Reject Threshold	Port Closure /Logout Threshold	Interval
New Release	401	501	Three-second window
Production	100	200	Three-second window

Detailed information on messaging controls is available in the Client Systems Wiki.

This change is currently available in New Release.

iLink Convenience Gateways Behavior Harmonization - January 6, 2019

To simplify the iLink session behavior, effective Sunday, January 6, 2019 (trade date Monday, January 7). All Convenience Gateway (CGW) iLink sessions will move to MSGW-style Session Connection and Resend Request. The following CGW features will as a result match the MSGW current state.

iLink Convenience Gateways Behavior Harmonizations
Functionality	Current Behavior	New Behavior	Certification Required
Duplicate Session Connection Attempts	Accepted, then disconnected	Ignored	No
Resend behavior from CME Globex to Client System	No real-time messages are published until the customer’s resend request is satisfied	Real-time messages will be interleaved with resend responses CGW customers must be able to receive out-of-sequence during a resend response without triggering another resend request	Yes Please Note - A new CGW Resend Request certification test is currently available in Autocert+. Certification via AutoCert+ is mandatory for all iLink CGW customers.

These changes are currently available in New Release for customer testing.

CME Group will offer the iLink mock trading session on Saturday, October 20. This mock trading session will offer customers the opportunity to interact with the system and experience the new iLink CGW behavior harmonization in the CME Globex production environment. An overview to the mock trading session script is now available.

Please note that customers are required to register in advance in order to participate in the iLink mock trading session.

Drop Copy is not impacted by this change.
