Bombay Stock Exchange (BSE) is planning to allow trading through mobile phones and has invited broker-members to register with its wireless platform. This will allow investors to place buy or sell orders using mobile phones. The guidelines for wireless trading (which includes mobiles and laptops with data cards) were issued in August 2010 by market regulator Securities and Exchange Board of India (SEBI). The National Stock Exchange (NSE) has already started trial trading via wireless technology for its members.
