In order to reach out to more customers, the National Stock Exchange (NSE) is gearing up to launch trading over mobile phones through nearly 800 registered brokers in early October, an NSE official said. At present, only about 10-15 big brokers have the infrastructure to offer mobile trading and it comes at a very high cost. “For the first time in India, NSE is taking steps towards facilitating nearly 800 members and their clients to trade through the mobile infrastructure set up by NSE from early-October,” the NSE official said. In early October, the NSE will enable any registered broker or a client to trade through their mobile phones.
