Volatility Analytics: Vol Radar with IV rank, variance risk premium and scans across every F&O name

The problem

Most option trades are lost on price, not on direction.

The chain shows you a premium. It doesn't tell you whether that premium is expensive for this name, cheap against how the stock is actually moving, or skewed to one side.

You sell premium when it's cheap

An IV of 20 means nothing on its own. If it sits at the 10th percentile of the name's own year and realised vol is higher, a short straddle is being paid too little for the move.

You buy wings nobody priced for you

Puts on one name can sit 3 vol points over the calls while the next name's calls are rich. Without a skew read you pay for the expensive side without knowing it.

You compare names in the wrong units

A ₹4,000 straddle on one stock and a ₹900 one on another say nothing about which is richer. You need vol in percentiles and P&L on the same notional to rank them.

Questions

Everything else you might ask.

Which underlyings are covered?

Every NSE and BSE F&O underlying with a usable option chain — 217 names, including NIFTY, BANKNIFTY, SENSEX and the stock F&O universe. MCX commodities are not included.

How is implied volatility calculated?

Black-76 on the futures price: the forward is the same-expiry future, refined by put-call parity at the strikes nearest the money — that removes the call/put IV gap you get when spot is sampled at a different moment. The interest rate does not set the forward; it only discounts the premium (6.5%, the same convention as the Options app’s Stock Volatility page), which moves IV by about 0.03 vol points on a two-week option. End-of-day surfaces use each contract's median close between 15:10 and 15:25 IST, and a leg is only used when it has open interest and enough prints in that window.

What do IV percentile and VRP mean here?

IV percentile is where today's implied vol sits in that name's own history (300+ sessions) — P10 is cheap for this stock, P90 is rich. VRP (volatility risk premium) is implied minus 20-day realised vol: positive means options are priced above how the stock has actually been moving, which favours sellers.

Is it really free?

Yes — every tool is open to every FNOTrader account with no plan. Without a plan, today's intraday surface is 15 minutes delayed; with any active plan it runs to the last closed minute, and with a plan plus a connected broker it is live. Past sessions are identical for everyone.

Can I place trades from it?

No — it is an analytics app. Take the structure to the Options app or the QuikTrade Terminal to execute it.

Is this investment advice?

No. FNOTrader is a technology product, not a SEBI-registered investment adviser or research analyst. The picks, scores and signals are decision-support data for informational and educational use only — not a recommendation to buy or sell any security. Options trading carries substantial risk; consult a SEBI-registered adviser before trading.
