A single margin order can create multiple trade positions depending on how many trades are used to fill the order. The order position consolidates all the trade positions under a single position so it's easier to see the net result of the margin order.
Order positions can be seen under Trade > Positions in your account. All order positions begin with “O”. To view the trade positions consolidated under an order position, click the icon on the left of the order position. All trade positions begin with “T”.
