Live option chain for indices, commodities and F&O stocks
The option chain compares calls and puts at each strike for the selected underlying and expiry. Read last traded premium, open interest, OI change, volume, implied volatility, PCR and combined straddle value alongside the underlying price.
Start near the at-the-money strike, keep units and observation times consistent, and use replay to review available historical snapshots. OI counts contracts with both a buyer and seller. Pattern labels describe premium and OI changes; directional interpretations depend on call or put side, underlying price action, IV and time decay. Strong or Weak describes relative OI change, not predictive confidence.
How do you analyze an option chain?
Choose a symbol, expiry and observation time. Compare the underlying price with nearby strikes, then review option premiums, OI change, volume and IV together. OI labels describe price-and-position patterns; they do not establish market direction or identify who initiated trades. Use replay to check how the setup developed.
What does Nifty 18000 CE mean?
It identifies a Nifty call option with a strike of 18,000. Check the expiry and applicable contract lot size before comparing premiums or calculating position value.
How to read OI data in option chain?
OI counts outstanding contracts, each with a buyer and a seller. Bars show concentrations across strikes; OI change shows the net change from the data reference point, not gross buying or selling. Compare the same expiry and time basis. OI alone cannot distinguish directional trades from hedges or spreads.
What if put OI is high?
High put OI shows concentrated outstanding put positions. These may include directional buying, protective hedges, writing or spread legs. Calling a strike support assumes put writing is relevant and the underlying price holds that area; OI alone does not establish either condition.
How to read IV in option chain?
Implied Volatility (IV) represents the market's expectation of future price movement and directly impacts option premiums. In our options chain, IV is displayed as a percentage for each strike price for both calls and puts. Compare IV across different strikes to identify volatility skew, look for strikes with unusually high or low IV compared to nearby strikes, and track IV changes using the replay feature.
How do CE and PE respond?
With other pricing inputs held constant, calls generally gain value as the underlying rises and puts as it falls. IV changes and time decay can offset that effect. Put Long Buildup or Short Cover may be consistent with a bearish underlying move; put Short Buildup or Long Unwinding may be consistent with a bullish move, only if underlying price action supports that interpretation and volatility or decay is not driving the premium change.
How to find if the market is bullish or bearish?
Start with the underlying price trend. Call premium gains may support a bullish reading and put premium gains a bearish reading only when price action agrees and IV or time decay is not the main driver. PCR above 1.5 highlights put-OI concentration and below 0.5 call-OI concentration; neither threshold establishes direction. High call OI as resistance or put OI as support assumes relevant writing activity and must be checked against price reactions.
What is the straddle strategy?
A straddle combines a call and put at the same strike and expiry. A long straddle needs enough movement or a favourable volatility change to overcome its cost and decay; a short straddle benefits from limited movement but carries substantial loss risk. The Straddle column adds the two last traded premiums, which may differ from executable prices.
How can I use the historical replay feature?
Our unique historical replay feature allows you to analyze how the options chain evolved throughout the trading day. Use the play/pause button and speed controls, drag the timeline slider to specific time points, track changes in OI, volume, or prices, and observe pattern changes. This feature is valuable for post-market analysis and learning from historical price action and option chain dynamics.

How to Read and Use the Option Chain
Compare calls and puts for a selected symbol and expiry, review OI, premiums, volume and IV, and replay available historical sessions. This guide explains the controls and how to interpret positioning without treating a single label as a trade signal.
What the Columns Show
At the heart of our page is a sophisticated data table that displays crucial information for both call and put options. You'll find metrics such as the combined straddle value (the sum of call and put LTP), last traded price (LTP), open interest (OI), changes in open interest (OI Change), implied volatility (IV), trading volume, and the put/call ratio (PCR). Horizontal OI bars help compare positioning across strikes, while PCR colors highlight relative put and call OI concentration.
The column selector allows you to customize your view by toggling specific data points, while the strike range selector narrows your focus to strikes around the current spot price.
Real-Time Market Data Visualization
Our options chain displays comprehensive data for both call and put options, allowing you to analyze:
- Current spot price with automatic highlighting of the nearest strike prices
- Last Traded Price (LTP) with color-coded price changes
- Open Interest (OI) displayed as intuitive visual bars for quick comparison
- OI Change with color indicators for increasing/decreasing positions
- Implied Volatility (IV) percentages for volatility analysis
- Trading Volume to assess liquidity
- Put-Call Ratio (PCR) with color coding to easily compare OI concentration
- Straddle Values for quick strategy assessment
Market Sentiment Analysis
Review positioning with these indicators; colors and labels alone do not establish a directional trade:
- Automated Call and Put Interpretation that identifies patterns like "Long Buildup," "Short Cover," "Short Buildup," and "Long Unwinding"
- Strength Indicators that assess whether patterns are "Strong" or "Weak" based on OI changes
- Color-coded PCR cells that highlight put-OI (>1.5) or call-OI (<0.5) concentration
- Premium Skew Chart that visualizes option pricing disparities across strike prices
Interactive Premium Skew Chart
The premium skew chart compares premiums across strikes. This chart visually displays option premium distribution across strike prices, marking the current spot price with a dynamic plot line. The visualization helps you:
- Identify where the premium curve shows steepness
- Compare premiums on either side of the spot price
- Compare asymmetry alongside IV, moneyness and time to expiry
- Investigate pricing differences; the curve alone cannot establish mispricing
Historical Options Data Replay - Our Unique Feature
Our exclusive options replay feature allows you to:
- Review historical options data to understand how markets evolved throughout the trading day
- Play, pause, and control replay speed (0.5x, 1x, 2x, 4x)
- Scrub through specific time points using an interactive timeline slider
- Study market movements and analyze how different events impacted option prices and sentiment
This replay feature is invaluable for learning how options markets behave under various conditions and can significantly improve your trading decisions by revealing patterns that might not be apparent in static data.
Display Format and Lot Conversion Options
Flexibility is key—users can toggle between a formatted view (which automatically appends units like "Cr" or "Lk") and a raw number display. Additionally, there is a switch to convert between lots and quantities, catering to instruments with varying lot sizes. Check the selected units before comparing values across symbols.
Analyzing Open Interest Patterns
These labels use changes in the option premium and OI, not changes in the underlying price. Every open contract has a buyer and seller; the labels do not prove which side initiated a trade.
- Long Buildup: OI increases and premium rises or is unchanged.
- Short Cover: OI decreases and premium rises or is unchanged.
- Short Buildup: OI increases and premium falls.
- Long Unwinding: OI decreases and premium falls.
A directional reading assumes the underlying move is driving the premium, with IV and time decay not dominating it. Under that assumption, rising call premiums may align with a bullish move and rising put premiums with a bearish move; falling premiums suggest the reverse. An unchanged premium offers no directional confirmation. Hedging and spread trades can produce the same OI patterns. Check the underlying trend, IV, volume and matching observation periods before drawing a conclusion. The Strong or Weak label measures relative OI change, not confidence or probability of profit.
Advanced Trading Strategies Using Our Options Chain
Our options chain is designed to support various trading strategies:
Straddle and Strangle Strategies
The options chain includes straddle value calculations. Open the straddle chart to track the combined premium over time, or use the chain to:
- Quickly assess the cost of straddle positions at different strikes
- Compare straddle values across strikes to identify volatility expectations
- Use this data for volatility-based trading strategies
Identifying Support and Resistance Levels
Compare the chain with open-interest analysis to investigate potential support and resistance levels:
- High call OI marks a concentration; potential resistance assumes relevant call writing and a confirming price rejection
- High put OI marks a concentration; potential support assumes relevant put writing and a confirming price hold
- Pay attention to how these levels evolve during the replay feature
Volatility Analysis
Use the IV column to assess volatility expectations:
- Compare IV across different strikes to identify skew patterns
- Track changes in IV during historical replay to understand how market events impact volatility expectations
- Compare elevated IV with event risk and its own history; high IV alone does not make option selling attractive
