Where COFORGE open interest sits
The heaviest call open interest is at the 2,000 strike, holding 12,17,900 contracts — 19.5% of all COFORGE call open interest on the board, 3.04% above the spot of 1,941. 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 1,900 with 7,41,475 contracts, 15.2% of COFORGE put open interest, 2.11% below spot. Put open interest concentrated below price is usually treated as support for the same reason, and breaks the same way.

What COFORGE's PCR is saying
COFORGE is carrying 48,92,975 contracts of put open interest against 62,46,725 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 0.78 and has held to 0.78 — a move of 0.00. That is effectively flat: positioning has not changed sides today.

COFORGE against its max pain
Max pain for COFORGE computes to 1,920, with spot at 1,941 — 1.08% above 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 1.0% more than 1,920 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 COFORGE today
The biggest unwind is −950 put contracts at 2,240. 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 COFORGE
The at-the-money straddle on COFORGE costs 106.70 — 51.70 for the call and 55.00 for the put at the 1,960 strike. That sum is what the market charges to be covered in either direction, which makes it the move being priced in: about 5.50% of spot, or roughly 1,853 to 2,067 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 27.8% on the call and 29.1% on the put. The put carries 1.2 points more, the usual shape when downside protection is bid up relative to upside.

COFORGE — frequently asked questions
What is the COFORGE ATM strike today?
The at-the-money strike for COFORGE is 1,960, taken from a spot reading of 1,941 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 COFORGE strike has the highest open interest?
The heaviest call open interest sits at 2,000 with 12,17,900 contracts, and the heaviest put open interest at 1,900 with 7,41,475 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.
