A Good Till Cancelled (GTC) order remains in the system until the trading member cancels it. However, the system cancels this order if it is not traded within a number of days parameterised by the Exchange. A Good Till Days/Date (GTD) order allows the user to specify the number of days/date till which the order should stay in the system if not executed. The maximum number of days for which the GTC/GTD order can remain in the system is notified by the Exchange from time to time after which the order is automatically cancelled by the system. The days counted are inclusive of the day/date on which the order is placed and inclusive of holidays. An Immediate or Cancel (IOC) order allows the user to buy or sell a security as soon as the order is released into the system, failing which the order is cancelled from the system. Partial match is possible for the order and the unmatched portion of the order is cancelled immediately.

At, all orders accepted are valid for GTD. Any unexecuted order pending at the end of the trading session for the day gets expired.
