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.

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.
