Where FEDERALBNK open interest sits
The heaviest call open interest is at the 360 strike, holding 61,67,500 contracts — 22.7% of all FEDERALBNK call open interest on the board, 5.06% above the spot of 343. 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 340 with 30,00,000 contracts, 19.0% of FEDERALBNK put open interest, 0.77% below spot. Put open interest concentrated below price is usually treated as support for the same reason, and breaks the same way.

What FEDERALBNK's PCR is saying
FEDERALBNK is carrying 1,58,22,500 contracts of put open interest against 2,71,80,000 of call, a put-call ratio of 0.58 — 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 0.58 and has held to 0.58 — a move of 0.00. That is effectively flat: positioning has not changed sides today.

FEDERALBNK against its max pain
Max pain for FEDERALBNK computes to 350, with spot at 343 — 2.15% 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 4.5% more than 350. A trough that distinct is a stronger reference than a flat basin, though it still describes positioning rather than predicting settlement.
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.

FEDERALBNK — frequently asked questions
What is the FEDERALBNK ATM strike today?
The at-the-money strike for FEDERALBNK is 345, taken from a spot reading of 342.65 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 FEDERALBNK strike has the highest open interest?
The heaviest call open interest sits at 360 with 61,67,500 contracts, and the heaviest put open interest at 340 with 30,00,000 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.
