A Non-Anonymous instrument will publish the market data message Long Order Update (1015) alongside the regular Order Update (1002). Inside the Long Order Update (1015), the member is identified by the field Firm ID. Kinematics can be found in the Euronext Cash Markets – Optiq Kinematics Specifications 4.2.0.

The webform for Front-to-Back Testing for Oslo Cash Interoperability is now available here. Trading members should use this form to confirm that they have successfully performed front-to-back testing between Euronext Optiq and their Clearing partner (Euro CCP/Six x-clear/LCH Ltd).

As a reminder and as mentioned in the Migration Guidelines (section, Trading Members must be aware that the current Oslo Børs mnemonics will no longer be used with the interoperable CCPs in the trade message reports following the migration to Optiq. Euronext cash trading participants are configured with the following codification in the Euronext membership forms:

–     Euronext Trading member ID, which is used to identify the trading participant in the Euronext Trading platform – Optiq, TCS and Saturn – and is conveyed in the order entry messages.

–     Trading Member BIC code, which is used to report the Trading Member’s unique ID in the real time trade report message to the interoperable CCP

–     Clearing Member BIC code, which is used to report the Clearing Member’s unique ID in the real time trade report message to the interoperable CCP.

As a consequence, further to the migration, the BIC code will be the reference to identify the trading participants in their front-to-back reconciliation with their clearing members.
