In the Orders Pane of the Trading Page, you may view your Order History and your Trade History. The Orders Pane is located beneath the chart on the bottom of the Trading Page. You can show or hide it by clicking on the Clock icon on the Layout Panel on the left.
The Order History includes all orders, even if they were cancelled.
Trade History is only Orders that fully completed successfully.
In the upper right corner of both of these tabs there is a button to export the contents of the table as a comma separated value or CSV file.
