SSF special order types

H

hii a_ooiioo_a

Two order types — All-or-None (AON) and Immediate-or-Cancel (IOC) — are unique to single-stock and narrow-based index futures. However, exchanges offering security futures also accept other orders, such as market, limit, stop, stop limit and stop with limit.


All-or-None (AON)
This order type specifies both a quantity and price. The order will be filled only if the entire quantity can be filled at the specified price. Thus, no partial quantities will be filled.

Immediate-or-Cancel (IOC)
An IOC order will be presented to the market, filled to the extent possible, and then immediately cancelled. Thus, you may receive partial fills on an IOC.
 
Actually both AON & FOK apply as well to options. FOK= Fill or Kill. Essentially the same as IOC.

Good idea though to start a thread like this on a relatively new instrument.
