FINNIFTY futures and options expire on the last Tuesday of every month. If that Tuesday is a trading holiday, expiry moves to the previous trading day. FINNIFTY no longer has weekly contracts.
In 2026, two months break the Tuesday pattern: March and November. Below is the full 2026 calendar, the current closing time, the lot size, and what to check before trading near expiry.
What Is FINNIFTY Expiry?
FINNIFTY expiry is the last day a FINNIFTY futures or options contract can trade. After that, the contract ends and open positions are settled in cash under exchange rules.
FINNIFTY tracks the Nifty Financial Services Index, which covers banks, NBFCs, insurers and other finance companies. To see which companies move it most, check the FINNIFTY stocks list and weightage.
Three monthly contracts are always open: near month, mid month and far month. So "monthly only" doesn't mean you're limited to one contract.
FINNIFTY Expiry Dates in 2026
These dates apply the last-Tuesday rule to NSE's 2026 F&O holiday list, published in circular FAOP71777. Under FINNIFTY's contract rules, if the last Tuesday is a holiday, expiry moves to the previous trading day.
NSE can add holidays during the year. It did this in January 2026 for the Maharashtra municipal elections. Always confirm the date shown on the contract before you place an order.
Does FINNIFTY Have Weekly Expiry?
No. The last weekly FINNIFTY contract expired on 19 November 2024.
From 20 November 2024, each exchange could offer weekly options on only one benchmark index. NSE kept Nifty 50 and dropped weeklies on FINNIFTY, Bank Nifty and Midcap Nifty.
The monthly expiry day changed later too. It moved from Thursday to Tuesday for contracts expiring from September 2025 onward.
If an older article or video says FINNIFTY expires every Tuesday, it's describing the old weekly setup. Nifty 50 is now NSE's only index with weekly options, and our Nifty expiry day guide explains how its weekly and monthly contracts differ.
FINNIFTY Expiry Time: When Does Trading End?
FINNIFTY derivatives trade until 3:40 PM IST, including on expiry day.
NSE extended the equity derivatives session by 10 minutes on 3 August 2026, when it launched the Closing Auction Session (CAS) in the cash market. The session now runs from 9:15 AM to 3:40 PM, so the old 3:30 PM close no longer applies.
Keep two things in mind:
Your broker may square off intraday positions before 3:40 PM, so check its cutoff times.
Trading stops at the close, but cash settlement follows the clearing schedule after that.
If you watch prices near the close, here's why the indicative closing price during CAS isn't the final close.
FINNIFTY Lot Size and Contract Specifications
The FINNIFTY lot size is 60 units. NSE cut it from 65, starting with the January 2026 monthly expiry.
The ₹0.05 tick size applies to options. FINNIFTY futures use a tick size linked to the index level.
Example: Premium for One FINNIFTY Lot
Say an option trades at ₹100 per unit. One lot costs ₹100 × 60 = ₹6,000 in premium, before charges.
If the premium rises to ₹120 and you sell, your gross profit is (₹120 − ₹100) × 60 = ₹1,200.
Option sellers work differently. The margin they need is separate from the premium they receive. To compare lot sizes across indices, see our NSE lot size guide.

How to Check FINNIFTY Expiry Contracts on AlgoTest
1. Pick the Right Monthly Expiry
Open the FINNIFTY option chain on AlgoTest and choose the expiry you want. Sign in if asked.
Check the full date, especially in March and November. Premiums from different expiries aren't directly comparable.
2. Find the Spot Price and Nearby Strikes
Start with the strike closest to the current index level, then compare the calls and puts around it.
It helps to know the trend before you read the chain. Our guide to FINNIFTY analysis with TradingView shows how to set up the chart and indicators.
3. Read OI, Volume and Bid-Ask Together
Open interest (OI) shows how many contracts are still open. Volume shows how much traded during the session.
Neither tells you whether your order will fill near the last traded price. For that, check the bid, ask and market depth. Spreads often widen near expiry, which is why liquidity in options trading matters so much.
4. Plan Your Exit Before You Enter
Think about how index moves, volatility and time left could change the premium. Then set your entry, stop-loss, position size and exit time.
New to reading the chain? Here's how to analyse the FINNIFTY option chain, field by field.
What Changes as FINNIFTY Expiry Approaches?
Time Value Runs Out
An option's time value drops to zero by expiry. Near-the-money options lose it fastest in the final days.
That doesn't mean premiums always fall on expiry day. A sharp index move or a rise in implied volatility can outweigh the decay.
Near-the-Money Options Can Swing Sharply
Close to expiry, a small index move can change the value of an option near its strike very quickly. There's also little time left to recover from a bad move.
So selling premium on expiry day isn't automatically safer. An unhedged short straddle can lose heavily if FINNIFTY moves hard. An iron condor caps the maximum loss, but you still need to manage fills and exits.
Open Interest Shifts Between Strikes and Months
As expiry nears, traders close positions or roll them to the next month. Falling OI in the expiring contract doesn't tell you whether the market is bullish or bearish.
High call OI isn't guaranteed resistance, and high put OI isn't guaranteed support. Every open contract has a buyer and a seller. You can track these shifts strike by strike on the FINNIFTY option chain, but read them together with price and liquidity.
What Happens to FINNIFTY Options at Expiry?
FINNIFTY options are cash-settled, so no shares change hands.
In-the-money options are exercised automatically and settled at their intrinsic value, using the final settlement price.
At-the-money and out-of-the-money options have no intrinsic value and expire worthless.
Expired positions don't roll over on their own, so you need to close the current position and open a new one in a later expiry.
For a call, intrinsic value is the final settlement price minus the strike, with a minimum of zero. For a put, it's the strike minus the final settlement price, again with a minimum of zero.
Ending in the money doesn't guarantee a profit. The premium you paid and your charges still count.

Common FINNIFTY Expiry Mistakes to Avoid
Many traders still follow the old weekly schedule, so always confirm the monthly contract date.
Not every 2026 expiry falls on a Tuesday, since March and November expire on Monday.
Exits planned around the old 3:30 PM close can go wrong, so work with 3:40 PM and your broker's cutoff.
The last traded price isn't always the price you'll get, so check the spread and available quantity first.
A strike with high OI doesn't guarantee a reversal, so treat it as context rather than a signal.
Old weekly backtests may not hold for monthly contracts, so review them before reusing them.
Entering without an exit plan leaves your risk open, so decide your maximum loss and exit time first.
Turn Your Expiry Checks Into a Tested Strategy
A FINNIFTY expiry trade is easier to judge when its rules are written down. Define the context, entry, exit and position risk, then check how the setup holds up across past expiries, including holiday-adjusted months, and in live market conditions.
