More detailed information on transaction reporting

Report the transaction in several reports if required by the type of trading. The same transaction may call for several transaction reports, for example if an executed transaction is allocated to several clients. Report transmitted orders yourself or make arrangements for their reporting by the receiving investment service provider.

The overall view provided by the transaction reports must reflect the changes in your position or your client's position due to the transaction. Your reports must also reflect the roles of yourself, your counterparty, your clients and the parties acting for clients under a power of representation.

Where both parties to a transaction are investment service providers, they report for themselves. However, the following elements in both reports must match: venue, transaction time, quantity, quantity currency, price, price currency, up-front payment, currency of up-front payment and details of the financial instrument, where necessary.
