NSE Implied Volatility (IV) Tool IV ToolImplied volatility is what the market is charging for uncertainty, and it moves an option's price as much as direction does. This tool pulls IV for any NSE contract — by symbol, expiry, strike and CE or PE — as both a sortable table and a chart, so you can see whether volatility was rich or cheap when a trade was on.
What implied volatility measures
Implied volatility is not a measurement of the stock. It is solved backwards out of the option's own price: the volatility figure you would have to feed a pricing model for it to return the premium the contract actually trades at. So it describes what the option market is currently charging for uncertainty, not what the underlying has done.
That distinction matters because it is the number most often confused with historical volatility, which is measured from the stock's own closing prices over a past window. One is a record of what happened; the other is what today's option price implies about what might. They can point in very different directions, and comparing them is a large part of why both are worth having.
Why it moves an option price as much as direction does
Volatility is one of the five inputs a pricing model takes, and its effect is not small. A contract can lose value on a day the stock moves in its favour, if implied volatility fell far enough over the same session — a pattern that appears reliably around events, where volatility is bid up beforehand and collapses once the outcome is known. Watching the premium alone makes that look inexplicable; watching IV alongside it makes it ordinary.
This tool pulls implied volatility for any NSE contract by symbol, expiry, strike and side, as both a sortable table and a chart. Where the exchange published a figure, that value is used unchanged. Where the stored history does not carry one — which is true of much of the older data — it is solved out of the traded premium with Black-Scholes, using that session's strike, spot and days to expiry, so the series stays continuous rather than breaking wherever the exchange field was blank.

Frequently asked questions
What is implied volatility in options?
Implied volatility is the amount of future movement the market is pricing into an option. High IV means options are expensive because a big move is expected; low IV means they are cheap. It is derived from the option price itself rather than measured from past prices.
Can I see historical IV, not just today's?
Yes. Set a date range and the tool returns IV per day for the contract you picked, so you can see whether volatility was expanding or collapsing while a position was open.
Why is IV different for calls and puts at the same strike?
Demand differs. When traders are paying up for downside protection, put IV runs above call IV — that gap is the volatility skew, and it is one of the more useful things this table shows.
Does high IV mean I should sell options?
High IV means options are richly priced relative to their recent history, which is why sellers watch it. Whether selling is sensible depends on your risk and what is driving the IV — results and events can justify a high reading. This tool reports the data; it does not give advice.
