The procedure for selling dematerialised securities is very simple. After you have sold the securities, you would instruct us to debit your account with the number of securities sold by you and credit your broker's clearing account. This delivery instruction has to be given to us using the delivery instruction slips given to you by us at the time of opening the account. Procedure for selling securities is given here below

	You sell securities in any of the stock exchanges linked to NSDL through a broker;
	You give instruction to us to debit your account and credit the broker's account;
	Before the pay-in day, your broker gives instruction to us for delivery to clearing corporation;
	Your broker receives payment from the stock exchange [clearing corporation] ;
	You receive payment from the broker for the sale of securities

For receiving demat securities you may give a one-time standing instruction to us. This standing instruction can be given at the time of account opening or later. Alternatively, you may choose to give separate receipt instruction every time some securities are to be received. The transactions relating to purchase of securities are summarised below:

	You purchase securities through a broker ;
	You make payment to your broker who arranges payment to clearing corporation on the pay-in day ;
	Your broker receives credit of securities in its clearing account on the pay-out day;
	Your broker gives instructions to us to debit clearing account and credit your account;
	You receive shares into your account. However, if standing instructions are not given at the time of opening the account, you will have to give 'Receipt Instructions' to your DP for receiving credit,.
	You should ensure that your broker transfers the securities from its clearing account to your depository account, before the book closure. If the securities remain in the clearing account of the broker, the company will give corporate benefits (dividend or bonus) to the broker. In that case, you will have to collect the benefits from your broker.

Any trade settled through a clearing corporation is termed as a 'Market Trade'. These trades are done through stockbrokers on a stock exchange. 'Off Market Trade' is one, which is settled directly between two parties without the involvement of clearing corporation. The same delivery instruction slip can be used either for market trade or off-market trade by ticking one of the two options.

In a bank account, credit to the account is given only when a 'pay in' slip is submitted together with cash/cheque. Similarly, in a depository account 'Receipt in' form has to be submitted to receive securities in the account. However, for the convenience of investors, facility of 'standing instruction' is given. If you say 'Yes' for standing instruction, you need not submit 'Receipt in' slip every time you buy securities. If you are particular that securities can be credited to your account only with your consent, then do not say 'yes' [or tick] to standing instruction in the application form.

If you are delivering securities to your sub-broker you need to fill-in the off-market trade portion of the delivery instruction slip.

No. Trading at the stock exchanges can be done only through a registered trading member (broker) of the stock exchange irrespective of whether the securities are held in physical or dematerialised form.

Trading is compulsorily done only in Demat form. So DP account is a must.

Yes. As in the physical segment, you can go long or short in the demat segment also.

No, a broker cannot directly inquire about the holding details of his clients from the clients DP.
