Market Insight

Our role as market operator means we have unique access to market data that can deliver significant improvement and change. In this section you can access our market charts as well as the MOSL portal, which houses trading party-specific data. This section will also contain outputs from our Data Insight improvement programme as well as a downloadable catalogue of the external data services that MOSL provides.

You can also find a link to the outputs from our Market Data Strategy and Roadmap, such as the Market Data Services document and Data User Personas.

Please note that we are in the process of updating and improving our market charts. If you'd like to provide feedback on any of the updates, please email performance@mosl.co.uk. Introductory videos on how to use the Market Insight dashboards and maps can be found in the Training and Guidance section of the website.
