Customers must log in to the MX Axis portal and begin linking all session IDs to the SAIL B4 version starting today end of the trading session and have until July 21, 2024, to complete this task. Failure to do so will result in order entry session login being denied by the exchange on July 22.
On the MX Axis portal link the session ID to 'Order Connector v255 - B4'.

Support of iLink 3.0 for the TT CME Convenience Gateway has now been deployed for customer use. In the same way as the MSGW iLink3 upgrade of 2019, this new Convenience Gateway version supports the CME “On Demand” order entry method only.

Please note that existing CGW Connections will not work as-is. In order to use the CME upgrade, New Connections must be created (A) using a Session ID that was created by CME specifically for iLink3, and (B) using Type = “Convenience Gateway iLink3” in TT Setup.

Aside from the changes to Connections, the order routing functionality of TT CGW iLink3 is identical to TT MSGW iLink3. All existing FIX configurations, Order Tag Defaults, etc. will continue to function as expected.

Options Chain

For the following options , TT was referring to the wrong underlying instrument . This has been fixed now

This has now been corrected per the Eurex page

Each of these option product has expiry on calendar months and quarterly months . Quarterly months here are Mar , Jun , Sep and Dec ; while the calendar months are the subsequent months till the next Quarterly month . For e.g. , in Apr , the calendar months will be Apr , May and Jun , and quarterly months will be Sep , Dec and Mar .

The future underlying for calendar months should be the upcoming quarter month , while the future underlying for quarterly months should be the same quarter .

All the EEX Instruments ( Spot and Derivatives ) were assigned the Derivative exchange in PDS . Due to this , just by subscribing for EEX Derivative instruments in TTUS , users could view both EEX SPOT and derivative products . This has now been corrected . If users want to view EEX SPOT products on TTW , they need to subscribe to EEX SPOT products in TTUS .
