LTF Open Interest — frequently asked questions5
What is the total open interest in LTF options?

LTF carries 1,70,46,000 contracts of call open interest and 1,73,40,750 of put open interest across the 29 Sep 2026 expiry, 2,94,750 more on the put side. That works out to a put-call ratio of 1.02, which on open interest alone reads as mildly put-heavy positioning. Figures are market close, 8 Sep 2026.

Which LTF strikes are acting as support and resistance?

The heaviest put open interest sits at 315 with 30,78,000 contracts, and the heaviest call open interest at 330 with 32,19,750 contracts. With spot at 308.75, those strikes bracket the range the option market is positioned around. They are crowding observations rather than levels that must hold — they break regularly, usually when the open interest behind them unwinds rather than defends.

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.

Who are option writers and why does their positioning matter?

Writers are the sellers of an option contract, taking the premium in exchange for the obligation. Because a writer carries open-ended risk, large written positions tend to be defended, and the strikes carrying the heaviest written open interest are the ones price most often stalls around. That is a description of where the crowd sits, not a guarantee about what price will do.
