@ Sonam...with respect to your NSE circular....i think this is how it works -
"It means that NSE does not intend to get the client accounts settled with the balances lying with other exchange (BSE)."?
No. NSE and BSE are two different exchanges and entities and cannot make such settlements.
The exchange has accounts of brokers and look into their settlement.
It is the broker who will maintain client accounts and has to settle them.
From the perspective of stock exchange, I have nothing to do with clients....I would deal only with my members i.e. brokers. If a broker has bought stock of some amount, for himself or client doesnt matter....whether client gives money or doesnt...the broker has to pay me. So for exchange, business is only with their brokers.
For the purpose of quarterly/monthly settlement trading member may settle across segments of the same exchange for a particular client.
This is exactly what im saying, that a trading member may settle across segments of same exchange. For example, If i have a debit of 1 lakh on NSE F&O and a credit of 5 lakh on NSE Cash, the settlement can be done withing segment.
However, if I have a debit of 1 lakh on NSE F&O, no credit in NSE Cash, credit of 2 lakh in BSE....in that case the broker will settle with NSE against my credit and settle my account on net basis as explained by Ramesh
