Member Connectivity

To become a member of NYSE Euronext, the following steps should be completed:

  • Approval of the membership application and member code assigned.
  • Order a physical connectivity solution to SFTI, either directly or indirectly via an accredited Application Service Provider (ASP) or Extranet Service Provider (ESP)
  • Select the protocol and the platforms you want to develop for the NYSE Euronext European Cash Markets. For Order Entry, we support two sets of protocols: the standard Fix 4.2 and the proprietary UTP-Direct Protocol. Click here for all specifications and configuration parameters.
  • Develop the application. To test it, request Order Entry Sessions (SLEs) on the EUA platform by completing the CCG Configuration Form and emailing it to the Support Team (; or Tel: +33 (0)1 49 27 50 80).
  • Once the application is fully validated, schedule a conformance test with the Customer Technical Support Group (CTSG). The full test lasts for 1-1.5 hours depending on your requirements.
  • Following a successful completion of the conformance test book a ‘Go Live’ connectivity test of your production order entry sessions (SLEs) with the European Service Desk (; or Tel: +33 (0)1 49 27 50 50).

The order entry sessions (SLEs) will be available the following working day within the production environment.
