Where BANKEX open interest sits
The heaviest call open interest is at the 66,000 strike, holding 6,600 contracts — 21.8% of all BANKEX call open interest on the board, 2.79% above the spot of 64,207. 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 64,000 with 3,300 contracts, 13.1% of BANKEX put open interest, 0.32% below spot. Put open interest concentrated below price is usually treated as support for the same reason, and breaks the same way.

What BANKEX's PCR is saying
BANKEX is carrying 25,260 contracts of put open interest against 30,300 of call, a put-call ratio of 0.83 — broadly balanced 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 0.83 and has held to 0.83 — a move of 0.00. That is effectively flat: positioning has not changed sides today.

BANKEX against its max pain
Max pain for BANKEX computes to 65,000, with spot at 64,207 — 1.23% 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 3.1% more than 65,000. A trough that distinct is a stronger reference than a flat basin, though it still describes positioning rather than predicting settlement.
There are 16 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 BANKEX today
The biggest unwind is −30 call contracts at 72,900. 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 BANKEX
BANKEX is not carrying enough open interest this session for a meaningful expected-move calculation. The table above is the full picture the exchange feed gives for this underlying — on a thin book, a single trade can move a strike to the top of the list, so no level is called out here.

BANKEX — frequently asked questions
What is the BANKEX ATM strike today?
The at-the-money strike for BANKEX is 64,800, taken from a spot reading of 64,207.42 on the 24 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 BANKEX strike has the highest open interest?
The heaviest call open interest sits at 66,000 with 6,600 contracts, and the heaviest put open interest at 64,000 with 3,300 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.
