DAY, GTC (good-till-cancelled), FAK (fill and kill), FOK (fill or kill), and ICBG (iceberg) are the order options that you can choose on this DOMTrader menu.
•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 or GTC 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.
