In absence of trading in any of the constituent of the underlying |

For example, on the day of expiry, if index value arrived based on VWAP of the constituents of the underlying Index during the above said period is 11,800.15, then DDR for the contract would be 11,800 (rounded off to the nearest tick) and if index value is 11,800.50, then DDR for the contract would be considered as 11,801 for settlement purpose. | |
