F&O expiry

F&O expiry is the date when futures and options contracts settle and cease to trade.

Index and stock derivatives on NSE follow exchange-defined weekly or monthly expiry cycles.

Open positions must be closed, rolled, or held into settlement before expiry processes run.

Expiry days often see elevated volumes, wider spreads, and sharper moves near key strikes.

Physical settlement rules apply to many stock F&O contracts at expiry in India.
