The National Stock Exchange today said it has started mobile trading for registered clients, a move that would make trading simpler for the customers.

The service will enable member brokers to only go through the regular compliance before facilitating their clients for mobile trading, National Stock Exchange (NSE) said in a statement.

"This is another facility the exchange is providing to the large universe of investors, to make trading simpler and easily accessible to clients on the move. We expect that nearly five million investors would benefit from this move," NSE CEO and MD Ravi Narain said.

NSE claimed that for the first time an Indian exchange would provide such facility free of cost to its clients, through the brokers who have enrolled for NOW (the software which is being used by a majority of the NSE brokers).

Earlier, just a few member brokers had the option of providing this facility to the clients at their own cost, it added.

In September, the country's oldest stock exchange BSE, had also launched mobile-based trading.

With the NSE's new service, the clients will be able to trade in the cash, derivatives or currency market through their mobile phones, while travelling anywhere in the country or abroad.

The clients' mobile will be connected to the Internet, then to the NOW platform, which is connected to the exchange, it added.

The service will provide a wide range of facilities to the investors where they can see the 'Market watch' page on his or her mobile screen. This will display all the available indices and constituents of these indices.
