New New - Description Change and Renaming of Rounded and Unrounded Settlements  - This Week

On Wednesday, August 9, CME Group changed the description and renamed the rounded and unrounded settlement price types in the Client Systems Wiki to provide greater clarity.

There will be no change to market data messaging behavior or format with this change.

Renaming of Rounded and Unrounded Settlements
Current Name	New Name	Updated Description
Rounded	Settlement at Trading Tick	The Settlement at Trading Tick is the instrument’s settlement price rounded to the product’s CME Globex trading tick. Some CME Group products’ trading tick is less granular than their clearing tick (e.g., clearing ticks at a penny, but trading ticks at a nickel). Settlement at Trading Tick prices are often used for front-end display purposes and to calculate net change aligned to the trading tick.
Unrounded	Settlement at Clearing Tick	The Settlement at Clearing Tick is the instrument’s settlement price at the Clearing tick precision. This value is used by CME Group Clearing for marking to market and margin calculations.

Globex Risk Management Enhancements: Inline Credit Controls - This Week

Effective this Sunday, August 13, in addition to existing risk management controls, CME Group will offer optional, more granular pre-trade risk management capability through the In-Line Credit Control (ICC) tool.

The ICC tool allows Clearing Member Firms and Executing Firms to set daily position limits for CME Globex, per product, at the account level through Account Manager.

Risk Administrators are encouraged to register and set limits in all products. Please review the complete ICC enforcement schedule.

The new functionality will feature:

• Daily quantity position limits applied per product at the account level.
• Positions reset to flat at the end of the day. Good 'Til Cancel (GTC) and Good 'Til Date (GTD) orders will roll-over to be calculated in the next day’s working orders.
• No latency differential; all orders are subject to the same ICC processing.
• Both Clearing Member Firm and Executing Firm Risk Admins can register accounts and set limits.
  • The most restrictive limit applies.
  • Clearing Member Firm and Executing Firm Risk Admins can view each other's account limits.
  • Clearing Member Firms and Executing Firms cannot change the other's limit.
• Email alerts can be set up when pre-set threshold level breaches occur (for example, at 80%).

Please note: With the introduction of ICC, clients may see minor changes in order entry round trip times (RTT) during large market events.

Initially, ICC processing for accounts approaching their pre-set threshold level, In-Flight Mitigation(IFM) enabled orders may temporarily violate account limits resulting in a reject. See scenario here. Future phases of ICC will accommodate In-Flight Mitigation and eliminate the temporary account limit violation scenario.

See more on Viewing and Managing Inline Credit Control Limits and Configuring Alerts and Policies for Inline Credit Controls.

For registered client systems, a new or cancel/replace order that violates specified position limits will be rejected. CME Globex will send a Session Level Reject (tag 35-MsgType=3) message including tag 58=<Reject Reason>.

Reject Reason	Tag 58-Text
Position Limit Violation	Position Limit Violation for Account: <Account>, Position Increase: <position> makes position above the BUY Position Limit: <Limit> by amount: <Amount>. Limit set by CMF for Product Code: <Product Code>
	Position Limit Violation for Account: <Account>, Position Increase: <position> makes position above the BUY Position Limit: <Limit> by amount: <Amount>. Limit set by EF for Product Code: <Product Code>
Account Policy Violation	Pre-Trade Registration Violation: Account: <Account> is not Registered for this Executing Firm

Self-Match Prevention Enhancements - September 24

Effective Sunday, September 24 (trade date Monday, September 25) CME Group will launch enhancements to CME Globex Self-Match Prevention (SMP). SMP is optional functionality that allows market participants to prevent the matching of orders for accounts with common ownership if both the buy and sell orders contain the same SMP ID and Globex Firm ID.

With these enhancements, iLink customers will have the ability to configure SMP functionality across multiple Globex Firm IDs within or across clearing firms. Upon this release, orders submitted with unregistered SMP IDs will be rejected. CME Globex will send a Session Level Reject (tag 35-MsgType=8) message including tag 58=<Reject Reason>. All Good 'Till Cancel (GTC) and Good 'Till Date (GTD) orders with unregistered SMP IDs must also be updated to use a registered SMP ID by the close on the Friday before launch. Any remaining GT orders with unregistered SMP IDs will be eliminated at Sunday start-up on launch weekend.

The Firm Administrator Dashboard interface will continue to be used to request new SMP IDs but will be enhanced to allow existing SMP IDs to be modified to support additional Globex Firm IDs.

Detailed information, including the launch schedule, is available in the Client Impact Assessment.

The new SMP enhancements are currently available for customer testing in New Release. Customer certification is not required, but CME Group strongly recommends all system providers test these changes thoroughly in New Release.

Please note: Clients planning to test the SMP enhancements in New Release must contact their Global Account Manager to receive new SMP IDs, which will be activated after the New Release daily maintenance period (16:00 to 16:45 central time).

Please contact your Global Account Manager with any questions or concerns in the U.S. at +1 312 634 8700, in Europe at +44 203 379 3754 or in Asia at +65 6593 5505 for additional information.
