Duration:
Users can set durations on orders which allow the order to expire at different times.
1) Day - this option allows the user to set an order that will expire at the end of the trading day.
2) Good till Cancel - this option allows the user to create an order with no expiration, and is a live order until explicitly cancelled by the user.
3) Immediate or Cancel - this option allows the user to create an order that needs to be immediately triggered or the order is cancelled.
4) Fill or Kill - this option allows users to create orders that must fill in entirety or the order is cancelled.
5) Good till date - this option allows users to create orders that are live until the end of the specified trading day.

Note: OCO, OPO order responses come back as one message, even though they have two orders associated.
1) OCO - The OCO group type allows users to configure contract pairs such that one order being triggered will cancel the other.
2) OPO - The OPO group type allows users to configure contract pairs such that one order being triggered will activate the other.
