NIFTY is at 23,226.20, -0.94% on the day. The 23250 straddle for the 29 Sep expiry costs ₹227.20 (115.85 call + 111.35 put), which is the market pricing a one-standard-deviation move of about ±227 points, ±0.98%, over the 5.3 days to expiry. Read that as the expected range: 22,999 to 23,453. Roughly two expiries in three should finish inside it; the third is where the money is made and lost.
India VIX at 11.20 is in its ordinary range: premium is fairly priced, and the edge comes from structure and sizing rather than from volatility being mispriced. Skew is mild (+0.0 IV points): neither side of the chain is paying up, so structures can be built symmetric around spot.
Priced off this chain, an iron condor collects ₹3,770 a lot with a maximum loss of ₹2,730 and breakevens at 23,092 / 23,408. The short strangle underneath it collects ₹9,207 — ₹5,437 more — for a loss that has no ceiling. That difference is the price of sleeping through a gap; decide whether it is worth paying before the market decides for you.
On the other side, the long straddle costs ₹14,768 a lot and needs NIFTY beyond 23,023 or 23,477 at expiry to pay. It bleeds about ₹1,401 a day in time value right now. Buy it only if you expect the market to move more than it is charging for — and know why.
Open interest across the loaded strikes: the largest call open interest above spot sits at 23,500 — the strike writers are defending as resistance; the largest put open interest below sits at 23,000, the floor.
