DEFINITION OF 'IMMEDIATE OR CANCEL ORDER - IOC'
An IOC order requires all or part of the order to be executed immediately, otherwise the order (or any unfilled parts of the order) will be canceled. Partial fills are accepted with this type of order duration, unlike a fill-or-kill order, which must be filled immediately in its entirety or be canceled.
