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.
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.
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.
