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 currently available in Certification for customer testing.

Eurodollar Futures Displayed Quantity Order Ratio

A New Order that fails to meet the ratio threshold will be rejected with an execution level reject message (tag 35-MsgType=8), with tag 103- OrdRejectReason=2190 and tag 58-Text= Message rejected due to MaxShow ratio violation. 'MaxShow ratio of [total quantity]:[displayed quantity] does not meet the ratio requirement of 60:1'.

iLink Session ID Auto-Deletion Process
On Monday, May 5, CME Group will execute 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.

Please contact your  Global Account Manager in U.S. at 312-634-8700, in Europe at 44-203-379-3754, or in Asia at 65-6593-5574 for further information.
