Where MARUTI open interest sits
The heaviest call open interest is at the 14,000 strike, holding 5,91,400 contracts — 16.4% of all MARUTI call open interest on the board, 10.75% above the spot of 12,641. 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 12,000 with 1,45,600 contracts, 9.6% of MARUTI put open interest, 5.07% below spot. Put open interest concentrated below price is usually treated as support for the same reason, and breaks the same way.

What MARUTI's PCR is saying
MARUTI is carrying 15,10,000 contracts of put open interest against 36,08,400 of call, a put-call ratio of 0.42 — 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 0.42 and has held to 0.42 — a move of 0.00. That is effectively flat: positioning has not changed sides today.

MARUTI against its max pain
Max pain for MARUTI computes to 13,000, with spot at 12,641 — 2.84% 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 pain curve around it is flat — the neighbouring strikes cost writers only 1.8% more than 13,000 does. A basin that shallow means several strikes are near-equally cheap to settle at, so the level is a weak magnet and small shifts in open interest can move it.
There are 21 sessions to expiry. This far out the figure moves as positions roll, and it is least informative early in a series — worth watching for direction of travel rather than as a target.

What changed in MARUTI today
The biggest unwind is −100 call contracts at 11,700. 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 MARUTI
The at-the-money straddle on MARUTI costs 455.65 — 221.95 for the call and 233.70 for the put at the 12,700 strike. That sum is what the market charges to be covered in either direction, which makes it the move being priced in: about 3.60% of spot, or roughly 12,244 to 13,156 by expiry on a breakeven basis.
The straddle has moved 0.0% since the open. That is close to flat, so today's decay and any volatility move have roughly offset.
Implied volatility at the money is 18.9% on the call and 18.7% on the put. The two legs are priced almost identically, so there is no meaningful skew at the money right now.

MARUTI — frequently asked questions
What is the MARUTI ATM strike today?
The at-the-money strike for MARUTI is 12,700, taken from a spot reading of 12,641 on the 29 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 MARUTI strike has the highest open interest?
The heaviest call open interest sits at 14,000 with 5,91,400 contracts, and the heaviest put open interest at 12,000 with 1,45,600 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.
