What is an 'Immediate Or Cancel Order - IOC'
An immediate or cancel order (IOC) is an order to buy or sell a security that must be executed immediately, and any portion of the order that cannot be immediately filled is cancelled. An IOC order is one of several "duration orders" that investors can use to specify how long the order remains active in the market and under what conditions the order is cancelled.
BREAKING DOWN 'Immediate Or Cancel Order - IOC'
Investors can place a variety of security trades that indicate a minimum price of a sell order or a maximum price before a sell order is filled. Orders can include other conditions, such as an instruction to fill the entire order or only a portion of the trade.
How Large Security Trades Are Filled
An IOC order requires all or part of the order to be executed immediately, and any unfilled parts of the order are cancelled. 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 cancelled. An IOC order may be used when a large order is submitted to the market. To avoid having a large order filled at a wide variety of prices, an IOC automatically cancels any part or the order that does not fill immediately. Assume, for example, that a client places an IOC order to purchase 500,000 shares of IBM common stock. Any portions of the 500,000 shares that are not purchased immediately are cancelled.
