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.

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.
