Figures in orange moved to the previous trading day because the scheduled date is a holiday.

How expiry works

An index option or future is a contract with an end date. On that date it stops trading and settles against a closing value, and whatever the contract is worth at that moment is what you are paid or what you pay. Everything else about options pricing, time value above all, is counting down to it.

Weekly against monthly

A weekly contract is written for a few days of life, a monthly one for several weeks. The practical difference is how fast the time value drains. A weekly option close to the money loses value quickly in its final two sessions, which is what makes expiry-week premium selling attractive and expiry-day short gamma dangerous. A monthly contract gives the same directional view more room to be right slowly.

Since November 2024 India has had far fewer weekly contracts than it once did. SEBI restricted each exchange to one weekly expiry, judging that the previous arrangement, where something expired almost every day of the week, was pulling retail traders into very short-dated speculation. NSE kept its weekly slot for Nifty. BSE kept its for Sensex. Everything else became monthly.

What settlement actually means

Nifty and Bank Nifty options are European and cash settled. You cannot be assigned early, and nothing is delivered. On expiry day the contract settles against a value computed from a closing window rather than the last traded price, so the final print you see on the chart is not necessarily the number your contract settles against. Stock options are the exception: those are physically settled, and an in-the-money short position can leave you with a delivery obligation.

What changes on expiry day

• Time value collapses. An at-the-money option has only intrinsic value left by the close, so anything out of the money goes to zero.
• Gamma turns violent. A short position near the strike sees its delta swing hard on small moves, which is where most expiry-day losses come from.
• Liquidity concentrates in the expiring series and thins elsewhere, so spreads on far strikes widen.
• The holiday rule bites. If the scheduled day is a holiday, expiry is the previous trading day, which shortens the week and compresses the decay into fewer sessions.

Common questions

Dates are generated from the current NSE and BSE expiry rules and adjusted against the exchange trading holiday list, last reconciled on 3 October 2026. Exchanges publish the following year's holidays in December, so next year's shifted dates appear here once that circular is out. Always confirm a date with your broker or the exchange before trading it. NiftyWise is educational and not SEBI-registered; nothing here is investment advice.
