Long Option Delivery Margin for Physically Settled stocks

What will happen if I have insufficient delivery margin during the day when position is taken?

If you have insufficient delivery margin during the day and if the day falls between Expiry - N days then your position will get squared off. Please keep sufficient limits in F&O segment to meet the 'delivery margin required' amount as displayed on the open position page against your position requiring margin and this amount will get updated immediately on execution of your position, if taken after Expiry- N trading day i.e. when the delivery margins are made applicable.
