In ASBA when the money is blocked? Before closing date or after closing date of IPO?

When you apply for an IPO, the application money is frozen. If you withdraw from the IPO prior to the closing of the IPO, the money will be immediately unblocked. You cannot withdraw the money, but the blocked money will still earn interest. You will not see the amount in your account until you receive allotted shares. If shares are not allocated, the money will not be blocked until the finalization.
