NIFTY is at 23,635.10, -0.61% on the day. The 23650 straddle for the 15 Sep expiry costs ₹259.85 (153.05 call + 106.80 put), which is the market pricing a one-standard-deviation move of about ±260 points, ±1.10%, over the 6.6 days to expiry. Read that as the expected range: 23,375 to 23,895. Roughly two expiries in three should finish inside it; the third is where the money is made and lost.

India VIX at 11.23 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 (-1.6 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 ₹4,137 a lot with a maximum loss of ₹2,363 and breakevens at 23,486 / 23,814. The short strangle underneath it collects ₹11,203 — ₹7,066 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 ₹16,890 a lot and needs NIFTY beyond 23,390 or 23,910 at expiry to pay. It bleeds about ₹1,278 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.

Elsewhere: BANKNIFTY 56,778 with a straddle of ₹1,303 (±2.29%, expiry 29 Sep); SENSEX 75,578 with a straddle of ₹561 (±0.74%, expiry 10 Sep).
