Data gathered by LuxSE are centralised and hosted on the Euronext UTP platform. Until 17 May 2017, the UTP platform is using the XDP protocol, after this date, we will replaced the current platform with the Euronext Optiq one.

You may source real-time information directly from the Euronext platform or indirectly via an information provider.

  • XDP protocol for real-time data (until June 2017)

    Data vendors connect directly to Euronext through SFTI (Secure Financial Transaction Infrastructure) using the XDP (eXchange Data Publisher) protocol.

    As the technical platform of the Luxembourg market is hosted by Euronext, access to real-time information of LuxSE is through the same infrastructure and protocols as any other Euronext market feeds.

    To access the LuxSE market feed, you need to:

    • Have access to the SFTI (Secure Financial Transaction Infrastructure) network either through dedicated access or through an ISV (Independent Software Vendor) – list of ISVs
    • Develop or purchase an application that can decode feeds in XDP format.

    The XDP protocol is based on the multicast dissemination of market messages.

    Real-time information from LuxSE is disseminated on the following dedicated multicast groups:

    Services ID Primary feed Secondary feed
    100 - Luxembourg Stock Exchange Multicast Group: Port: 21046 Multicast Group: Port: 21047

    Using this feed does not require a procedure of the types "User Acceptance" or "Go Live" at Euronext and LuxSE.

    All detailed technical information, enabling access to feeds and to decode XDP messages, can be found on the Euronext website:

  • Web-linking and white-labelling

    If you wish to integrate LuxSE data, such as securities prices or price charts into your website, there are two approaches:

    • We authorise the use of a link to the LuxSE website and you carry out its implementation into you applications.
    • Our programmers develop the tailored information you wish to display and adapted to match it with your corporate identity.

    In both cases, you first need to enter into an agreement with the Luxembourg Stock Exchange. For further information, please contact us at:
