Order Validity Date means the date chosen by you while placing Cash orders with GTDt order validity. This date has to be equal to or less than the maximum validity date defined by ASL which would appear as the default date against the date field besides GTDt order validity. For example, if the maximum days defined by ASL are upto 90 calendar days then the order validity date can be less than or equal to the default date appearing against the date field besides GTDt order validity. If the trade date is July 27, 2015, then October 24, 2015 would appear as the default date besides GTDt order validity. In this case you can choose the GTDt order validity date as less than or equal to October 24, 2015.
