Drop Copy Service for iLink

The Drop Copy service allows customers to receive real-time copies of CME Globex Execution Report and Acknowledgment messages as they are sent over iLink order entry system sessions on a separate, dedicated path.

Drop Copy aggregates iLink messages, enabling customers to aggregate positions and monitor orders for sessions guaranteed by one or more clearing firms upon approval of the clearing firms.

The Drop Copy service is available for iLink messages on orders submitted to the CME Globex platform via iLink or CME Direct. Customers can choose to receive the following message types over a Drop Copy connection configured to the following three levels:

Trade Execution Reports: These messages can be used to determine a customer's filled positions.

• iLink 2 Execution Report - Fill Notice (complete and partial fills)

• iLink 2 Execution Report - Trade Cancel

• iLink 2 Execution Report - Trade Correction

Order Entry Acknowledgments: These messages can be used to determine a customer's filled positions.

• Execution Report - Order Creation, Cancel, or Modify

• iLink 2 Execution Report - Order Elimination

• iLink 2 Order Mass Action Report

All of the Above including:

• All Trade Execution Reports

• All Order Entry Acknowledgments

Customers may connect to Drop Copy via an existing network connection or establish a new connection dedicated to the Drop Copy service.

Coordination with Global Account Management (GAM)

To initiate Drop Copy functionality, customers must submit the Schedule 12-Drop Copy Service form specifying the name of the Drop Copy Group, how billing for Drop Copy is to be administered, which message types are received over the Drop Copy session, and individuals authorized by the Clearing Firm to administer changes to the Source sessions configured for the Drop Copy group. Once the approved request form is submitted, the Global Account Manager initiates scheduling and configuration. The customer receives standard connection information for the Drop Copy Target session(s) including:

• SenderCompID – seven digit alphanumeric value consisting of:
  
  

  • 6-character Session ID

  • 1-character Fault Tolerance Indicator = 'N' (no fault tolerance)

• IP primary address

• IP backup address

• Port

• Password

For questions about Drop Copy, related to iLink or CME Direct, please contact Global Account Management (GAM).

Drop Copy Fees

Configuration of the Drop Copy service should be requested through your Global Account Manager. Once the completed Schedule 12 is submitted all configuration requests for Drop Copy must be submitted by an authorized contact for the Drop Copy Group.  The configuration request should include which iLink Source sessions should be configured to feed the Drop Copy Group as well as the message types the customer wishes to receive for the Drop Copy Group. 

Customers can also choose to implement Drop Copy Automation based on their Execution Firm ID or if they are a Clearing Firm (CME Class A Clearing Firm ID). See Schedule 12, Section II B for details or contact your Global Account Manager.

A monthly fee for the Drop Copy service is charged as a separate line item on regular monthly CME Globex connection billing. This fee is assessed on a per Drop Copy Group basis with the fee waived for the customer's first Drop Copy Group.

Drop Copy Bandwidth Impact

Since Drop Copy Target sessions transmit Acknowledgment and Execution messages only (no market data), bandwidth impact should be minimal, but is dependent upon the number of Source sessions bundled to the Drop Copy Group. Drop Copy uses the same packet size as an outbound iLink message, i.e., thirty Source sessions will use the equivalent bandwidth of thirty iLink Source session Execution Report and reject messages.
