Shares purchased by you upto the value of your Debit Balance will stay in our Client Unpaid Securities Account (CUSA) for T+6 Days. If you fail to initiate the Pledge request or clear the debit balance by making the requisite payment, then the debit balance will be cleared by us on T+7day by selling the shares from our CUSA account.
