Each time an order has been executed, you will receive a confirmation of the transaction via e-mail.
You can manage these notifications in your personal Settings. To change the status of this notification, go to "Settings" and then select "Notifications".
Under "Feedback order status", you can turn the confirmation e-mails on or off.
In the unlikely event that you do not receive an e-mail confirmation, we are unfortunately unable to reproduce it for you. However, you can of course find all your executed transactions in your account.
