Should the need arise for you to modify or delete a pending order that you have placed, locate the order in the ‘Terminal’ window at the bottom of your MT5 screen. Open orders appear above your account details, while orders that haven’t yet been executed appear below them. Right-click or double-click on the order you wish to modify or delete. A pop-up menu will appear that will allow you to select ‘Modify or Delete Order’. The ‘Order’ window will appear and enable you to change the price at which the order is triggered, to re-set the expiry date of the order, to set stop-loss and take-profit levels or to delete the order altogether.
You may also delete an order by clicking the ‘X’ symbol at the bottom right corner of your MT5 terminal.
