Reporting Requirements and Member Obligations
All information required by Euronext to fulfil its reporting obligations as a market operator must be provided for each order comprising a wholesale trade, where applicable. This includes data required under EU Delegated Regulation 2017/580.

For the avoidance of doubt, the registration of trades via the Euronext Block Execution Service (BES) does not relieve the trading members of their regulatory obligations - either to their clients or to the competent authorities - in their role as an order-executing investment service provider.

In the event of an error related to an off-order book trade - whether by the executing member(s) or Euronext - it is the responsibility of the member(s) to request a trade cancellation in accordance with Euronext Notice 4-02: Order Withdrawal and Trade Cancellation.
