+===== Immediate-Or-Cancel Order =====
+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**.
