Where NIFTY open interest sits
The heaviest call open interest is at the 23,650 strike, holding 3,02,20,385 contracts — 12.6% of all NIFTY call open interest on the board, 0.06% above the spot of 23,635. 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 23,600 with 2,04,54,070 contracts, 14.0% of NIFTY put open interest, 0.15% below spot. Put open interest concentrated below price is usually treated as support for the same reason, and breaks the same way.

What NIFTY's PCR is saying
NIFTY is carrying 14,56,51,220 contracts of put open interest against 23,91,83,880 of call, a put-call ratio of 0.61 — 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 0.56 and has risen to 0.61 — a move of +0.05. Puts have been added faster than calls since the open, which is the footprint of put writing below spot or of call unwinding above it.

NIFTY against its max pain
Max pain for NIFTY computes to 23,650, with spot at 23,635 — 0.06% below it. That strike is where the total value of all open contracts expiring would be lowest. It is arithmetic on the current open interest distribution, not a forecast, and the distribution keeps changing.
The curve is defined around it: the nearest strike either side costs writers 11.3% more than 23,650. A trough that distinct is a stronger reference than a flat basin, though it still describes positioning rather than predicting settlement.
This is the expiry day set by the exchange. Max pain matters most in the final hours, when remaining time value is smallest and the distribution can no longer change much.

What changed in NIFTY today
The largest fresh call position went on at 23,650, +2,94,20,690 contracts (+3679.0%). Its premium fell over the same window, which is the footprint of call writing rather than call buying.
On the put side the heaviest addition is at 23,600, +1,03,59,050 contracts (+102.6%). Premium fell alongside it — put writing, which is usually read as support being built at that strike.
The biggest unwind is −94,95,525 call contracts at 23,900. Positions closing matters as much as positions opening — a level defended by open interest stops being defended when that open interest leaves, and a break through a strike that is unwinding is a different event from a break against one that is intact.
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 NIFTY
The at-the-money straddle on NIFTY costs 14.90 — 0.05 for the call and 14.85 for the put at the 23,650 strike. That sum is what the market charges to be covered in either direction, which makes it the move being priced in: about 0.06% of spot, or roughly 23,635 to 23,665 by expiry on a breakeven basis.
The straddle has moved −86.2% since the open. Premium coming out that quickly usually means implied volatility is falling, time is passing, or both — which is why an option position can lose money with the direction called correctly.
Implied volatility at the money is 170.2% on the call and 170.2% on the put. The two legs are priced almost identically, so there is no meaningful skew at the money right now.

NIFTY — frequently asked questions
What is the NIFTY ATM strike today?
The at-the-money strike for NIFTY is 23,650, taken from a spot reading of 23,635.1 on the 8 Sep 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 NIFTY strike has the highest open interest?
The heaviest call open interest sits at 23,650 with 3,02,20,385 contracts, and the heaviest put open interest at 23,600 with 2,04,54,070 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.
