Why does one receive an SMS and Email from NSE, and BSE when trading?

When you trade in the stock market, you receive confirmations of your activity from both the National Stock Exchange as well as the Bombay Stock Exchange. This is part of a regulatory mechanism to ensure that investors are aware of and have authorised the transactions that take place in their account. The messages sent include the instruments traded in, the price, quantity and time of the trades.

If you receive a message or email for a trade you didn’t authorize, you can quickly contact your broker to take action to identify and resolve the discrepancy.
