Where FINNIFTY open interest sits
The heaviest call open interest is at the 29,000 strike, holding 56,400 contracts — 55.9% of all FINNIFTY call open interest on the board, 18.67% above the spot of 24,437. Call open interest concentrated above price is commonly read as resistance, on the reasoning that writers there are defending the level. It is a crowding observation, not a rule — the level holds until that open interest unwinds.
On the put side the weight is at 24,600 with 30,780 contracts, 39.3% of FINNIFTY put open interest, 0.67% above spot. That strike is in the money, so it is not acting as support — price is already beneath it. Heavy in-the-money put open interest more often reflects protection bought before the move than a level being defended now.
Both sides are unusually concentrated — the top strike alone carries 55.9% of its side. A distribution that peaked puts a large share of the Open Interest on one strike, with little at the next. Where that Open Interest is closed or added to, the reading for that level changes quickly.

What FINNIFTY's PCR is saying
FINNIFTY is carrying 78,300 contracts of put open interest against 1,00,980 of call, a put-call ratio of 0.78 — mildly call-heavy positioning. PCR has no universally good value; it is read against its own recent range, and the direction it is moving carries more than the level.
It opened the session at 1.30 and has fallen to 0.78 — a move of −0.53. Calls have been added faster than puts since the open, the reverse footprint — fresh call writing above spot, or puts being closed.
The two sides changed places during this session — FINNIFTY opened with puts carrying more open interest and now has calls ahead. A crossover marks the point where the larger side of the book swapped, and is worth more when it comes from fresh writing than from the other side unwinding.

FINNIFTY against its max pain
Max pain for FINNIFTY computes to 24,600, with spot at 24,437 — 0.67% below it. That strike is where the total payout to option buyers at expiry is smallest. It is a level read from the current Open Interest distribution, not a prediction, and the distribution keeps changing.
The curve is defined around it: the total payout at the nearest strike either side is 7.1% higher than at 24,600. A trough that distinct is a clearer reading than a flat basin, though it still describes the book and does not predict settlement.
There are 26 sessions to expiry. This far out the figure moves as positions roll. It is a level read from the book, not a target.

What changed in FINNIFTY today
The largest fresh call position went on at 25,000, +7,740 contracts (+121.7%). Its premium rose over the same window, pointing to buyers lifting the strike rather than writers selling it.
On the put side the heaviest addition is at 24,600, +30,720 contracts (+51200.0%). Premium fell alongside it — put writing, which is usually read as support being built at that strike.
Change is measured against this session's opening snapshot rather than the previous close, so the overnight gap and the positions rolled at the open do not swamp the reading.

The move priced into FINNIFTY
The at-the-money straddle on FINNIFTY costs 900.85 — 436.90 for the call and 463.95 for the put at the 24,550 strike. That sum is what the market charges to be covered in either direction, which makes it the move being priced in: about 3.69% of spot, or roughly 23,649 to 25,451 by expiry on a breakeven basis.
Implied volatility at the money is 16.9% on the call and 16.9% on the put. The two legs are priced almost identically, so there is no meaningful skew at the money right now.

FINNIFTY — frequently asked questions
What is the FINNIFTY ATM strike today?
The at-the-money strike for FINNIFTY is 24,550, taken from a spot reading of 24,437.15 on the 23 Nov 2026 expiry. The ATM strike rolls as spot moves, so it is re-selected through the session rather than fixed at the open. It carries the highest time value of any strike, which is why decay is felt most sharply there.
Which FINNIFTY strike has the highest open interest?
The heaviest call open interest sits at 29,000 with 56,400 contracts, and the heaviest put open interest at 24,600 with 30,780 contracts. Those two strikes are commonly read as the working range — calls above spot as resistance, puts below as support. They are crowding observations, not guaranteed barriers.
What is open interest in options?
Open interest is the total number of option contracts in a strike that are still open and not yet squared off or settled. It counts positions, not trades. Rising open interest means fresh contracts are being created and new money is entering that strike; falling open interest means existing positions are being closed out.
