Option chain data

Frequently asked questions

What is an option chain?

An option chain is a table showing all available call (CE) and put (PE) strike prices for an underlying like Nifty 50 or Bank Nifty, with key data per strike — last traded price (LTP), open interest (OI), volume, implied volatility (IV) and bid/ask. It is the primary tool F&O traders use to read where institutional money is positioned and where strikes are likely to act as support or resistance.

Is this NSE option chain free to use?

Yes. MarketsEasy option chain analyzer is completely free with no subscription, no credit card, and no usage cap. Sign in with Google for personalisation features like watchlist sync, but live option chain data works for everyone.

What is PCR (Put-Call Ratio) and how do I read it?

PCR is total Put OI divided by total Call OI for the selected expiry. Above 1.2 indicates put-heavy positioning (often bullish — puts are being written as support). Below 0.7 indicates call-heavy positioning (often bearish — calls are being written as resistance). Extremes above 1.5 or below 0.5 can signal contrarian reversals.

What is max pain in the option chain?

Max pain is the strike price at which the total dollar value of outstanding options (both calls and puts) is at a minimum — i.e. where option writers would lose the least on expiry. Spot prices tend to gravitate toward max pain as expiry approaches, especially in the final hour of expiry day.

What is a gamma zone and why does it matter?

A gamma zone is a strike range with extreme gamma exposure, usually near ATM and close to expiry. Small spot moves through these strikes cause amplified delta hedging by market makers, which can trigger rapid 5-20x premium spikes. Our analyzer flags gamma zones automatically.

How is this different from the NSE India option chain?

NSE India shows raw data tables. MarketsEasy adds live analysis on top — auto-computed max pain, PCR heatmap, gamma zone detection, IV smile chart, OI distribution chart, and expiry-day signal patterns. Same underlying data, much faster to make decisions from.

Which indices and stocks are supported?

Nifty 50, Bank Nifty, FinNifty, Midcap Nifty, Sensex, BankEx and all 200+ NSE F&O stocks. Each has its full expiry calendar (weekly + monthly) and complete strike ladder.

Understanding the NSE Option Chain

The option chain is the single most important screen for any F&O trader on the NSE. It lists every available strike price for an index or stock, showing the call (CE) and put (PE) side by side, along with the open interest, volume, implied volatility and price at each strike. Read correctly, it tells you where the market is positioned, where support and resistance sit, and how sentiment is shifting through the session. This page gives you a live, analyst-grade option chain for Nifty, Bank Nifty, FinNifty, Midcap Nifty, Sensex and every F&O stock — free, with the OI analytics layered on top.

What open interest (OI) tells you

Open interest is the total number of outstanding option contracts at a strike that have not yet been squared off. Rising OI at a strike means new positions are being built there; falling OI means positions are being closed. When large OI builds up on the call side of a strike, that strike often acts as resistance — writers are betting the index stays below it. Heavy OI on the put side tends to mark support.

The most useful reading comes from watching OI change through the day rather than the absolute number. A sudden jump in put OI at a strike below spot suggests fresh support forming; a jump in call OI just above spot suggests a ceiling. Our chain highlights these OI shifts with visual bars so you can scan the whole ladder at a glance.

PCR, max pain and gamma zones

The put-call ratio (PCR) is total put OI divided by total call OI. A high PCR (above ~1.3) often signals an oversold, potentially bullish setup as put writers dominate; a low PCR can indicate excessive optimism. Max pain is the strike at which option buyers collectively lose the most — and because option writers have an incentive to defend it, indices frequently gravitate toward max pain as expiry approaches.

Near expiry, gamma becomes the dominant force. At-the-money options carry the highest gamma, meaning small moves in the index cause large swings in option delta. Our gamma-zone analysis flags where this risk concentrates so you can size positions accordingly on expiry day.

How to use this option chain

Pick a symbol, choose an expiry, and narrow the strike range around the at-the-money level so the ladder stays readable. Watch the summary cards — spot, PCR, max pain and total call/put OI — for the headline read, then drill into individual strikes for OI change, volume and implied volatility.

Call OI build-up above spot → likely resistance
Put OI build-up below spot → likely support
PCR rising through the day → sentiment turning bullish
Index drifting toward max pain near expiry → pinning behaviour
