Requesting sample transaction reporting data

We provide samples of data back to firms after the submitted transaction reports have been validated. See how to request sample data.

Providing data samples to firms helps errors to be identified in the reports.

Under Article 15 of the Commission Delegated Regulation (EU) 2017/590 firms are required to regularly request data samples and reconcile their front-office trading records against these samples. Where data feeds are received into a front-office system these should also be included.

A firm will be able to request a sample of transaction reporting data where a user is identified as being associated with the executing or submitting entity identified on the transaction report.

How to request sample data

Requirements to request sample data

  • Trading venues that use an Approved Reporting Mechanism (ARM) to submit transaction reports for firms cannot request sample data. Trading venues should liaise with their ARM.
  • An executing or submitting entity can only make one request per day.
  • The maximum amount of data that can be returned in response to a single request is either 1 day’s worth of data, or up to 10 million records when based on a date range.
  • Sample data is only available once the transaction report has passed instrument reference data validation.

For more information, see the MDP entity portal pages.
