NSE Option Chain — Live Option Chains for Nifty, Bank Nifty, FinNifty & All F&O Stocks

If you trade options — or you're just starting out — the option chain is the one screen you'll come back to every single day. It's where the whole options market for a stock or index is laid out in a single table, and once you can read it, you can see where the market expects support, resistance and the next big move before price gets there.

This page is your starting point — a hub for every live NSE option chain on NiftyTrader. Let me walk you through what's on it, how to use it, and how to actually read an option chain like a trader rather than just staring at numbers.

What is an option chain? (in plain English)

An option chain (also written as "option chain NSE" or "options chain") is simply a table that lists every option contract available for one underlying — a stock or an index — for a chosen expiry. For each strike price it shows you both sides of the market:

• Calls (CE) on one side — contracts that profit when price goes up.
• Puts (PE) on the other side — contracts that profit when price goes down.
• Strike prices running down the middle — the price levels at which those contracts come into play.

Against each strike you'll see live numbers: open interest, change in open interest, volume, implied volatility, last traded price and bid–ask. Put together, those numbers tell you where traders are placing their bets — and that's the real value of an option chain. It's one of the few genuinely leading indicators in the market.

How to use this page (a quick walkthrough)

Think of this page as the front door. From here you can open the chain for any index or any F&O stock, or jump straight to today's most active contracts. Here's each part.

1. Pick an index chain

The Index Option Chains section gives you one-click access to the live chains for the major NSE indices. Each one opens a dedicated, real-time chain page built for that index. If you trade indices, start here and bookmark the one you watch most.

2. Search any F&O stock

The Stock Option Chains section is the powerful bit. You can browse 200+ F&O stocks two ways — By Activity (what's moving today) or the A–Z Directory (find a name fast). On top of that you get:

• Sector filters — Banking, IT, Auto, Pharma, FMCG, Energy — to narrow the list to the space you trade.
• Sort tabs — Top by Volume, Top by OI, Most Active Calls, Most Active Puts — to surface where the real action is right now.
• At-a-glance columns — LTP, change %, option volume, total OI, PCR and max pain — so you can shortlist a stock without even opening its chain.

Click any symbol to open its full strike-by-strike chain.

3. Scan "Hottest Options Today"

This is a strike-level snapshot of the single most-traded contracts across the market. Flip between Most Active, Top Gainers, Top Losers, OI Buildup and High IV, and filter by All / Index Options / Stock Options. It's the fastest way to spot momentum — the exact contracts other traders are piling into, with their volume, OI change and IV right there.

4. Jump to other segments

Need something beyond NSE equities? The "Looking for something else?" links take you to the BSE option chain, the commodities option chain (crude, gold, silver and more), the crypto option chain, and a stock futures snapshot.

How to read an option chain

Every chain on this site follows the same simple layout, so once you learn it for one symbol, you can read all of them.

• Strike prices sit in the centre column.
• Calls (CE) are on the left, Puts (PE) on the right.
• The strike closest to the current spot price is the ATM (at-the-money) strike — usually highlighted.

The key columns, and what each one is actually telling you:

• OI (Open Interest) — the total number of open contracts at that strike. Think of it as how much money is "parked" there. Big OI = a level the market cares about.
• Chng OI (Change in OI) — how much OI was added or removed today. This is often more useful than OI itself, because it shows fresh positioning.
• Volume — how many contracts changed hands today. High volume = liquid, easy to enter and exit.
• IV (Implied Volatility) — the market's expectation of how much the underlying will move. Higher IV = pricier options and bigger expected swings.
• LTP — the last traded price (the premium) of that contract.
• Bid / Ask — the best buy and sell quotes. A narrow gap means tight, liquid pricing.

And the three "moneyness" buckets you'll hear constantly:

• ITM (in-the-money) — already has intrinsic value; more expensive.
• ATM (at-the-money) — strike sits right at the spot price.
• OTM (out-of-the-money) — no intrinsic value yet; cheaper, but needs the price to move to pay off.

Reading the signals: support, resistance, PCR & max pain

Here's where the chain earns its keep. A few reliable reads:

• High Call OI = resistance. When lots of calls are written at a strike, sellers are betting price won't cross it — so it tends to act as a ceiling.
• High Put OI = support. Heavy put writing at a strike suggests sellers expect price to hold above it — a floor.
• PCR (Put-Call Ratio) = total put OI ÷ total call OI. Above 1 leans bullish (more put writing); below 1 leans bearish or cautious. Read it with the trend, never alone. See the live PCR analysis.
• Max Pain = the strike where option buyers lose the most (and writers profit most) at expiry. Price often drifts toward it near expiry. Check the live max pain chart.

Simple example. Say a stock is trading at ₹1,000. You open its chain and see the heaviest call OI at the ₹1,050 strike and the heaviest put OI at the ₹950 strike. Straight away you've got a likely range: resistance near ₹1,050, support near ₹950. If price approaches ₹1,050 and call OI keeps rising, sellers are defending that ceiling — useful to know before you buy a call expecting a breakout.

Advanced tips: read OI together with price

OI on its own is only half the story. Pair the change in OI with the change in the option's price and you can tell exactly what kind of positioning is happening. Here's the cheat sheet traders keep handy.

For Calls (CE):

For Puts (PE):

A few more habits that separate good chain-reading from guesswork:

• Follow the writers, not just the buyers. Option writers (sellers) are usually larger, better-capitalised players. Where they build positions tells you the levels they're confident defending.
• Watch IV around events. IV tends to rise before big events (results, RBI policy, the Budget) and collapse afterwards. Buying options into high IV and holding through the event often loses even when you're right on direction.
• Confirm, don't rely. Treat the chain as a complement to your chart and trend, plus context like India VIX and participant-wise OI. Then go deeper with OI analysis and intraday OI spurts.
• Test before you risk capital. Build and check setups in the Strategy Builder, screen the whole market with the Options Screener, and backtest on past expiries with the Option Simulator.

What you can customize on each chain page

When you open any individual chain, you're not stuck with one static view. Each chain page gives you controls to make it your own:

• Symbol selector — switch the underlying without leaving the page.
• Expiry selector — flip between all available weekly and monthly expiries. Near expiries for intraday, further-out ones for positional trades.
• View modes — toggle between LTP/OI (prices and open interest), Greeks (Delta, Gamma, Theta, Vega) and Info for the detail you need.
• OI Chart — see the strike-wise OI as a visual bar view, so support/resistance jumps out instantly.
• Filter & Settings — trim the strike ladder to the range around ATM and tailor what's displayed.
• Future Chart — pull up the underlying's price alongside the chain.
• Auto Refresh — keep the chain updating live (every minute) during market hours.

For an intraday OI-and-price flow view over time, the option chain time / OI timeflow tool plots how positioning built up through the session.

F&O lot size and margins — what you need to actually trade

Options aren't traded one share at a time. Every F&O contract has a fixed lot size — the minimum quantity in one contract — set and periodically revised by the NSE based on liquidity and index/stock price levels. (The exchange last rebased index lot sizes in the January 2026 contract series, for example.) Lot sizes vary widely from one stock or index to another, so always confirm the current number before you trade. You'll find the full, up-to-date list on the NSE F&O Lot Size page.

Lot size matters because it decides your contract value and therefore your margin:

• Contract value = lot size × price. A bigger lot means a bigger position — and bigger risk — per lot.
• If you buy an option (a call or a put), your maximum risk is just the premium you pay. No extra margin beyond that premium.
• If you write/sell an option, you must post margin — broadly SPAN + Exposure margin under the exchange framework — which can be substantial, because a seller's risk is open-ended. Hedged positions (spreads) usually need far less margin than naked selling.

The practical takeaway: leverage in F&O cuts both ways. Check the lot size, work out the contract value, and size your position so a bad day can't wipe you out.

A quick worked example: reading a chain end to end

Let's tie it together. Suppose you open a stock chain and see:

• Spot price ₹1,000, so the ₹1,000 strike is ATM.
• Biggest call OI at ₹1,050, and call OI there is rising while the call premium is falling.
• Biggest put OI at ₹950, with put OI rising and the put premium falling.
• PCR around 1.1, IV steady.

How to read it: heavy call writing at ₹1,050 (OI up, price down) says sellers expect that to hold as resistance. Heavy put writing at ₹950 (OI up, price down) says they expect that floor to hold too. PCR slightly above 1 and stable IV both lean mildly positive. Net read: a likely range of roughly ₹950–₹1,050, with a slight upward tilt. A range-bound trader might sell premium near those edges; a directional trader would wait for OI to shift before betting on a breakout. That's the chain doing its job — turning a wall of numbers into a clear picture.

NSE option chain — FAQs

What is an option chain?

An option chain is a table of all available call (CE) and put (PE) option contracts for an underlying stock or index, at every strike price for a chosen expiry. It shows live OI, change in OI, volume, IV, LTP and bid–ask, giving you a quick read on market sentiment, support and resistance.

How do I read the NSE option chain?

Strike prices run down the centre; calls are on the left, puts on the right. High call OI marks likely resistance; high put OI marks likely support. The strike nearest the spot price is the ATM strike. Pair change-in-OI with the option's price move (see the call/put tables above) to tell whether it's buying, writing, covering or unwinding.

What does PCR mean in an option chain?

PCR (put-call ratio) = total put OI ÷ total call OI. Above 1 generally leans bullish (more put writing); below 1 leans bearish or cautious. It's best read alongside the trend, not on its own.

What is max pain?

Max pain is the strike where option buyers collectively lose the most at expiry — and option sellers gain the most. Because writers are often large players, price frequently drifts toward the max-pain level as expiry approaches.

What is IV in an option chain?

IV stands for implied volatility — the market's expectation of how much the underlying will move. Higher IV means pricier premiums and bigger expected swings. IV usually rises before major events and falls afterwards.

What is open interest (OI)?

Open interest is the total number of outstanding contracts at a strike that haven't yet been closed out. Rising OI means fresh positions are being added; falling OI means positions are being closed. Only one side of each contract is counted.

Which option chains can I view on this page?

From this hub you can open live chains for every NSE index and 200+ F&O stocks, and jump to the BSE, commodities and crypto option chains. Each chain lets you change the symbol and expiry, switch between LTP/OI, Greeks and Info views, see the OI chart, and auto-refresh live data.

How often is the option chain updated?

Live NSE option chain data on NiftyTrader refreshes every minute during market hours (9:15 AM to 3:30 PM IST on trading days). After close, end-of-day OI and price are reconciled with the official exchange feed.

Do I need margin to trade options?

If you buy an option, you only pay the premium — that's your maximum loss. If you write/sell an option, you must post margin (broadly SPAN + Exposure), which can be large because a seller's risk is open-ended. Contract value depends on lot size — check the current list on the F&O Lot Size page.

Is the option chain data free?

Yes. Current-session option chain data is free once you signup and connect with your broker. Deeper historical data — OI build-up history, strike-wise PCR trends and intraday OI changes — is available to NiftyTrader Prime subscribers.
