The Nifty is trading on the Globex. This means it trades for almost 22 hours on the Chicao exchange. In the day, (when it was Monday morning in India and Sunday night in Chicago) the Nifty was trading with 2 contracts in volume and a price of 5384 which was almost equal to what we were having in India.
Now, as I write this, it is 7:23 PM in Delhi. The Nifty is trading in Globex with a volume of 41 contracts.
