What does Day, Immediate and Minutes Validity mean?

Day: Orders placed with Day validity remain open for the order matching until they are executed or till the market closes.

Immediate: Orders placed with Immediate or Cancel (IOC) validity allow a user to buy or sell a security as soon as the order is placed into the market. If the order is not executed, it gets auto-cancelled, and the order is removed from the system.

In an IOC order, a partial match is possible for the order, and the unmatched portion of the order is cancelled immediately. When IOC orders don't get matched, the error 16388: Unmatched orders cancelled by the system is displayed.

Minutes: Orders placed with Minutes validity are auto-cancelled if the order is not executed within a given period of time. This period of time is set in minutes. Minutes validity is not allowed in the BSE F&O (BFO) and MCX segments.
