Peak Margin

Will I be able to take positions in stocks Options contract on its adhoc expiry day?

On adhoc expiry all near, mid & far month contracts are expired and may be disabled at discretion of I-Sec. All ITM and few OTM which may become ATM/ITM due to volatility may be disabled for trading (at discretion of ICICI securities) and no fresh positions will be allowed if contracts are disabled.
