An Immediate-Or-Cancel Order (also known as Immediate-Or-Cancel IOC) is submitted to the exchange, filled as much as it can be, and the remaining volume (if any) cancelled immediately.
An Immediate-Or-Cancel Order is entered with the New Order Single (Tag 35=D) message. Following are the most relevant tags to build an Immediate-Or-Cancel Order:
| Tag | Field | Description |
|---|---|---|
| 59=3 | TimeInForce | Time In Force specifier of Immediate-Or-Cancel (IOC) |
| 48 | SecurityID | Market for which the order is sent |
| 55 | Symbol | Contract for which the order is sent |
| 207 | SecurityExchange | Exchange for which the order is sent |
| 167 | SecurityType | Security Type (e.g. Futures) of this specific market |
Sample
In this example, a 10-lot Immediate-Or-Cancel order is submitted for a limit price (Tag 44) of 62500 or better. As it is a buy order, a better price indicates a price lower than 62500.
