An investor purchasing securities intimates his broker to do so from the depository segment. After the deal is executed, the investor gives his depository participant a receipt with an instruction slip (or a standing instruction), thus authorizing the depository participant to credit his account with the purchased securities.

On the payout day, the securities due to the clearing member get credited into his account from the clearing corporation/clearing house. The clearing member then gives a corresponding delivery instruction slip to his depository participant, authorizing the transfer of the securities from his account into the investor’s account. to trade options that are now available are those with wider flexibilities. However, with the advent of virtual trading platforms, a transaction is completed at the click of a button.
