NIFTY is at 23,440.80, +1.68% on the day. The 23450 straddle for the 03 Nov expiry costs ₹167.85 (37.00 call + 130.85 put), which is the market pricing a one-standard-deviation move of about ±168 points, ±0.72%, over the 1.0 days to expiry. Read that as the expected range: 23,273 to 23,609. 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.
