Order Duration

DAY, GTC (Good-till-cancelled), FAK (fill and kill), FOK (fill or kill), and ICBRG (Iceberg) are the order duration options.

•      DAY is the default.  If a DAY order is unfilled at the close of the trading session, it is automatically canceled.

•      GTC orders are left open until canceled by the trader.

•      FAK orders are used to buy or sell a quantity at a limit price and if the entire order is not immediately filled the remaining quantity is cancelled.

•      FOK orders require that the entire quantity be executed immediately or the order is cancelled.

•      ICBRG orders are a limit day orders that have both a total quantity and a display quantity that is shown publicly on the order book.  These orders must be enabled in preferences.
