NSE, BSE to launch pre-trading auction

The nation's two premier bourses "National Stock Exchange and Bombay Stock Exchange" will start the 15-minute pre-open session call auction from October 18.
In a call auction practice, participants indicate their willingness to buy or sell units of a security by placing an order for a number of units at the prevailing price before the opening of trade.
The mechanism, known as 'pre-open session call auction', will last for a duration of 15 minutes (from 9:00 am to 9:15 am) and will be introduced on a pilot basis by the BSE and NSE.
