Call versus put implied volatility comparison for Indian options
Volatility CE-PE compares call and put implied volatility for the selected underlying. The timelines help examine whether the two sides reprice together or whether their IV spread changes through a session.
Compare matching expiry and moneyness, and check quote quality before interpreting a widening spread. Differences may reflect skew, liquidity, model inputs or hedging demand. A call-put IV gap alone does not establish directional intent, and convergence does not prove that an event is fully priced.
What does the Volatility CE-PE tool compare?
It plots call (CE) and put (PE) implied volatility for the selected underlying side by side, so skew, wing repricing and demand imbalance between the two sides are visible in one view.
What does a wide CE-PE IV gap usually mean?
A persistent gap means one side is being bid more aggressively, often around events or after gap opens. Directional demand, protective buying and systematic writing all show up here before they show up in price.
When does CE versus PE volatility converge?
Convergence is common in calm sessions and after the event being priced passes, when the expensive side decays faster. Expiry-day pinning can also compress both sides near ATM strikes.
How is this different from the Implied Volatility page?
The Implied Volatility page studies each contract's IV level, percentile and history. This page isolates the CE-versus-PE relationship: the spread, its direction, and how it moves through the session.

How to Read Call vs Put Volatility
A framework for comparing CE and PE IV, ATM skew, and changes in relative option demand.
Most important nuance
A CE-PE IV gap is contextual and may reflect skew, demand, liquidity, or model inputs rather than a standalone directional signal.
What It Tracks
Compare equivalent CE and PE moneyness.
Best Comparison
Anchor the spread to ATM IV.
Strongest Use
Track the CE-PE IV spread by strike for the selected expiry.
Main Risk
Confirm with events, spot, OI, and liquidity.
Functionality Available on This Page
ATM Focus
Identifies the ATM strike and keeps the CE-PE volatility comparison centered on executable contracts.
Skew Value
Calculates the call-versus-put IV difference for each displayed strike.
Regime Labels
Classifies rows as Put Premium, Call Premium, Balanced, or unavailable using the current skew.
Summary Diagnostics
Displays ATM IV context, average skew, regime counts, and relative volatility pressure.
Chart and Table
Combines the volatility chart with searchable strike-level CE IV, PE IV, skew, and regime rows.
Strike and Regime Search
Filters the desk table by strike or regime for faster analysis of a large chain.
Terminology Traders Actually Need
Implied Volatility Market-Implied Input
IV is the volatility input that reconciles an option-pricing model with the observed market premium.
Market Reading
Compare IV across strikes, expiries, and time to identify relative repricing rather than labeling one value high or low in isolation.
India Market Context
Indian index IV can reprice quickly around RBI decisions, budgets, elections, global events, and weekly expiry.
Caveat
IV is model-dependent and can be distorted by stale prices or wide bid-ask spreads.
Volatility Skew Relative Pricing
Skew is the difference in implied volatility across strikes or between comparable calls and puts.
Market Reading
Use changes in skew to assess where relative hedging demand or tail pricing is strengthening.
India Market Context
Downside put skew is common, but its normal shape varies by instrument, event risk, and expiry.
Caveat
Skew does not identify trade direction by itself and may reflect structural hedging demand.
CE-PE IV Spread Side Comparison
The CE-PE IV spread compares call and put implied volatility at equivalent or nearby moneyness.
Market Reading
Track the sign, magnitude, and persistence of the spread across the displayed strikes and regime labels.
India Market Context
Downside hedging demand can lift put IV, while sharp rallies or event positioning can change the normal Indian index relationship.
Caveat
Compare similar moneyness and active quotes; a raw CE and PE strike comparison can otherwise be misleading.
How to Use This Page
Start With ATM CE and PE
Use the ATM pair as the baseline before reading skew across the strike table.
Read the Spread and Regime
Compare the CE-PE IV difference, regime label, and summary diagnostics for the same expiry.
Inspect the Strike Distribution
Use the chart and searchable table to determine whether skew is broad or isolated to one strike.
Validate the Comparison
Check moneyness, event risk, OI, volume, and quote freshness before interpreting the CE-PE gap.
Institutional Read Framework
ATM Diagnostic
Track CE-PE spread near ATM first. When PE IV sustains above CE IV, downside hedging demand is dominating and directional risk tends to rise.
Expiry Positioning
Compare nearby expiries during event weeks. Expanding skew with stable spot often indicates defensive positioning before directional repricing.
Execution Bias
Use the volatility ladder with strike distance and regime tags to avoid chasing crowded strikes and anchor entries to cleaner risk-reward zones.
