 Intra Day Trading Sample Files 

  • Dear Market Participant

    SEMO would like to advise Market Participants that a set of Intraday Trading related sample files / reports, generated from the Factory Test of the MI system currently underway at the factory site, has been provided by our vendors. This set contains any reports that have new or updated fields in them and also contains samples of new reports being implemented for IDT. These files can be found here.

    SEMO are making these files available to Market Participants in an effort to aid the understanding of the changes being implemented in the Intraday Trading release. SEMO would also like to stress the following points:

      • The files have been produced from Factory Testing of the updated systems – the systems will undergo further testing (e.g. System Integration Testing etc.) as the project schedule progresses 
      • Thedata included in the reports is from the vendor test database – it is not reflective of Live SEM data
      • The Public Reports have a complete data set;
      • The MP specific reports contain a sample of data only (for data sensitivity reasons); and
      • These files are for sample purposes only - the Market Participant Update Document (MPUD) remains the definitive specification to which Participant interfaces should be built.

    Any queries in relation to these sample files should be sent to with a prefix of 'IDT' in the subject line, they will be forward directly to the relevant project team.
