What is Sensex Weekly Expiry?

Sensex options contracts are scheduled to expire every Tuesday. If a Tuesday falls on a trading holiday, the expiry is moved to the previous trading day.

Settlement occurs at the regular market closing time on the expiry day, unless the exchange announces a different schedule.

Furthermore, if the last Tuesday of the expiry cycle is a holiday, the expiry of individual securities within the same series is also shifted to the prior trading day.
