Starting Sunday, June 15, CME Group will launch a new risk management feature that will allow BrokerTec clients to cancel and modify resting orders using FIX tag 11-ClOrdID without providing tag 37-OrderID.  This feature will be enabled for all BrokerTec markets on CME Globex.

Testing and Certification

Certification in AutoCert+ is required for client systems that support the new Order Cancel and Cancel/Replace Requests by ClOrdID functionality.

Production Launch Schedule

Order Cancel and Cancel/Replace Requests by ClOrdID

BrokerTec markets will support cancellation and modification of orders by ClOrdID (tag 11). Client systems can cancel and/or modify their orders without providing an OrderID (tag 37). 

EBS Market and CME Group Futures and Options on Futures on CME Globex already support cancel and modify by ClOrdID.

iLink 3 Impacts

All iLink 3 sessions will be enabled for Order Cancel and Cancel/Replace by ClOrdID functionality. Clients who intend to use this feature must complete an AutoCert+ certification before using the functionality. Clients must have completed their migration to the new iLink 3 v8 schema in order to access this feature. Please see additional client system impacts for iLink 3 below.

Rejects for ClOrdID (tag 11) Uniqueness

To support order cancellation and order modification by tag 11-CIOrdID, this value must be unique per SenderComp (Session ID + Firm ID) for all working orders on a single market segment.

For an iLink 3 New Order tag 11-ClOrdID:

• CME Globex will reject an order having the same ClOrdID and SenderComp as a currently working order on the given market segment. A duplicate ClOrdID will generate an iLink 3 Business Reject (tag 35-MsgType=j) message with tag 380-BusinessRejectReason = 133 and tag 58-Text = Duplicate ClOrdID: X not allowed.

A ClOrdID value can be re-used on the same Market Segment only when the prior order is no longer resting, for instance:

• Prior order has been completely filled.

• Prior order has been cancelled.

• Prior order has been eliminated.

Processing for ClOrdID and OrderID Values

Effective with iLink 3 schema v8, FIX tag 37-OrderID is an optional tag in iLink 3 Order Cancel Request and iLink 3 Order Cancel/Replace Request messages for BrokerTec markets.

• If an Order Cancel Request or Order Cancel Replace Request contains both CIOrdID and OrderID, the OrderID will be used to look up the original order.

• If a ClOrdID in an Order Cancel Request or Order Cancel/Replace Request is changed from what was in the original order:

  • Client should send an Order Cancel Request or Order Cancel/Replace Request with the latest CIOrdID accepted by CME Globex.

  • Client sending an Order Cancel Request or Order Cancel/Replace Request with the previous CIOrdID must provide an OrderID as well; otherwise, the Order Cancel/Replace Request will be rejected as order not found.

• An Execution Report - Cancel and Execution Report - Modify message will return both ClOrdID and OrderID values.

• An Order Cancel Reject and Order Cancel Replace Reject message will return both ClOrdID and OrderID values.
