NIFTY is at 22,753.20, +0.68% on the day. The 22750 straddle for the 27 Oct expiry costs ₹191.40 (107.20 call + 84.20 put), which is the market pricing a one-standard-deviation move of about ±191 points, ±0.84%, over the 1.0 days to expiry. Read that as the expected range: 22,562 to 22,945. Roughly two expiries in three should finish inside it; the third is where the money is made and lost.

How to use it

Compare the implied move with what you expect. If the straddle is pricing ±0.8% and you think a result or an RBI decision makes ±1.5% plausible, the long side is cheap; if the range looks generous for a dull week, defined-risk selling is being paid. Then open the builder, size for the worst plausible loss, and journal the comparison — Finch chapter 6 explains the straddle rule, chapter 11 the sizing.
