Stock Market muhurat trading is been a tradition in India. Each Diwali NSE & BSE organize a muhurat trading for half an hour even on saturday or sunday as well.

For 2012 Diwali (November 13, 2012), NSE markets will be open from 3:30 PM till 5 PM with 15 minutes pre-market session

Happy Diwali and happy investing.

Cheers!
