Why do I receive a statement of accounts every week?
Stockbrokers are required to send a ledger statement and register of securities to their clients on a weekly basis. The ledger statement contains the details of your fund transactions for the period and the register of securities contains the transaction details of your holdings.
You will notice that there is a separate 'Pending' field in your ledger statement and also the register of securities.
The funds or securities under the 'Pending' field are not yet settled. For instance, say you buy 100 shares of Reliance on 5th March and you get this statement as on 6th March. Since Reliance is receivable by you but the stock exchange will only deliver it on T+2 days, it's said to be unsettled and will feature in the 'Pending' field.
