During the auction session, the exchange invites offers from fresh sellers for shares that are short delivered. A short delivery happens when the exchange is unable to deliver shares purchased to the demat account because the seller of the shares failed to do so. To learn more about short delivery, see What is short delivery and what are its consequences?

The auction usually takes place after 2:00 PM and lasts only 30 minutes. Only shares settled in the demat account can be sold during the auction. T1 quantities cannot be sold. Also, shares cannot be bought in the auction as the exchange is the buyer. The settlement cycle will be T+1 for the stocks sold in the auction market, 80 % of funds will be credited immediately when the stocks are sold and can be used to take new positions, whereas the remaining 20% will be blocked as delivery margin and will be available for trading or withdrawal from the next trading day.
