NIFTY is at 22,680.90, -0.44% on the day. The 22700 straddle for the 29 Sep expiry costs ₹127.05 (61.40 call + 65.65 put), which is the market pricing a one-standard-deviation move of about ±127 points, ±0.56%, over the 0.3 days to expiry. Read that as the expected range: 22,554 to 22,808. Roughly two expiries in three should finish inside it; the third is where the money is made and lost.

India VIX at 13.85 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 inverted (-3.9 IV points): calls are trading richer than puts, which usually means a chase for upside; call spreads carry the premium today.

Priced off this chain, an iron condor collects ₹2,077 a lot with a maximum loss of ₹4,423 and breakevens at 22,568 / 22,832. The short strangle underneath it collects ₹3,533 — ₹1,456 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 ₹8,258 a lot and needs NIFTY beyond 22,573 or 22,827 at expiry to pay. It bleeds about ₹15,844 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 23,000 — the strike writers are defending as resistance; the largest put open interest below sits at 22,500, the floor.

Elsewhere: BANKNIFTY 54,182 with a straddle of ₹394 (±0.73%, expiry 29 Sep); SENSEX 72,386 with a straddle of ₹792 (±1.09%, expiry 01 Oct).
