Migration Documentation

Planning a Euronext Optiq OEG Migration

Before You Begin

Use this document to plan a migration of users of NYSE Liffe Gateways due to the Euronext Optiq order entry API upgrade. Euronext will not migrate any orders to the new system. 

TT recommends that by close of market on Friday, November 22, traders cancel all working orders, including GTC, GTD, and GTDate orders entered for Euronext products, as any remaining SSE orders will become unmanaged after the upgrade. For TT User Setup changes, please refer to “How do I migrate traders in TT User Setup?”.

What are the major changes introduced by the API upgrade?

All exchange documentation may be found on the Euronext Customer Portal:

When should I migrate?

NYSE Liffe will conduct the Optiq OEG API upgrade in production on November 25, 2019

What testing is required by the exchange, and what are the required test dates?

Euronext will move forward with Phase 3 of its Optiq OEG API upgrade on November 25, 2019. Dates for testing as follows:

  • Saturday, November 9, hours TBD
  • Saturday, November 23 (Upgrade Weekend)
  • Monday, November 25, PROD

The mandatory Dress Rehearsals will take place before Go Live, allowing customers to test the target Production implementation of OEG and MDG for Derivatives markets in advance. 

Customers will not be authorised to take part in the Dress Rehearsal week-end unless they have:

  1. Validated their conformance test - TT to complete for TTNET
  2. Confirmed Telnet connectivity to Production - TT to complete for TTNET
  3. Ordered their OE Sessions for Production. - Customer must work with exchange

The scope of the tests are the following: 

  • Optiq Order Entry and Market Data Phase 3 for Derivatives markets 
  • The schedule and scope of Dress Rehearsals will be communicated at a later date in a dedicated document

How do I prepare my TT Trading Environment?

Can I upgrade an existing NYSE Liffe Gateway?

No. A clean install, or uninstall/reinstall is required.

What version of the NYSE Liffe Gateway should I use?

All users should migrate to NYSE Liffe Gateway 7.18.40, Which will be made available for testing in simulation in October, as well as for the Dress Rehearsals in Production.

This version CANNOT be used for production trading until the API upgrade on November 25.

For information on installing and configuring a NYSE Liffe Gateway, refer to the NYSE Liffe Gateway System Administration online help.

What are the minimum supported versions of TT Client applications?

Customers who utilize Wholesale order functionality must upgrade to X_TRADER 7.18.89 prior to November 25.

No additional client applications are expected to have version dependencies. Trading Technologies will notify customers, as well as update this document, should any additional dependencies be determined.

What is the Licensing and Billing Impact?

Can I reuse my current NYSE Liffe Gateway licenses?

Customers will be provided with the appropriate free gateway license(s) for use during conformance and exchange testing prior to the launch of the new API. Test license(s) must be requested by customers via the normal process, and they must also request a cancellation of test license(s) prior to the launch in order to avoid being billed.

For a description of TT licensing, refer to TT Gateway Architecture System Administration.

Canceling NYSE Liffe Licenses

During the conformance testing period, TT is offering customers NYSE Liffe Gateway licenses for temporary gateways used for conformance purposes free of charge. These licenses will become billable once the exchange goes live on the Optiq OEG API. Customers must submit license cancellations via the TT Website for TT NYSE Liffe Gateways that are no longer in use following the migration. TT will not automatically cancel any licenses.

Billing Server Impact

There is no impact on the TT Transaction Billing Server. After the migration, fills and billing packets will continue to be recorded and transferred daily to the TT Licensing Department Accounting and Billing System and will contain the Exchange ID of the newly installed NYSE Liffe Gateway.

The TT Licensing and Accounting Department will be notified by your TAM that the new gateway is installed and the exchange IDs have changed.
