Used in context of general equities. A limited price order that is to be executed in its entirety or not at all (no partial transaction), and thus is testing the strength/conviction of the counterparty.
Unlike an FOK order, an AON order is not to be treated as cancelled if not executed as soon as it is represented in the trading crowd but instead remains alive until executed or cancelled.
