Why does Zerodha email a weekly statement?

As per the exchange circular (ZIP), stockbrokers must send a ledger statement and register of securities to their clients every week. The statement contains the details of fund transactions and holdings.

The pending obligations in the statement show trades that are not yet settled, i.e. shares bought on Friday. If Friday were a trading holiday, the shares bought on the previous trading day would appear under pending obligations.

Example scenario

The weekly equity statement from 01-03-2021 (Monday) to 06-03-2021(Saturday) is sent to the client the following week. If shares were purchased on 05-03-2021 (Friday), then they would appear under pending obligations because, as on 06-03-2021 (Saturday), they are not yet settled.
