How do I modify or delete a pending order on MT4?
First, locate the order in the MT4 ‘Terminal’ window at the bottom of your MT4 screen. Open orders appear above your account details, while orders that haven’t yet been executed appear below them. Right-click on the order you wish to modify or delete and select ‘Modify or Delete Order’ or double-click on the order to bring up the ‘Order’ window. From the ‘Order’ window, you may change the price at which the order is triggered, re-set the expiry date of the order, set stop-loss and take-profit levels or delete the order.
