Option chain
An option chain groups listed calls and puts by underlying, expiry and strike.
Plain-language meaning
An option chain groups listed calls and puts by underlying, expiry and strike.
Why it is useful
Option chain is useful as descriptive evidence when it is compared on the same definition, source, period, unit and exact listing. It is one input to research, not a verdict.
Where it appears in XMarketRadar
Look for Option chain in Futures, Option Chain, Options Screener and derivative study tables for a selected underlying and contract.
How it is calculated or sourced
Option chain is sourced or derived according to the definition shown above and the screen's disclosed provider, inputs, window and as-of time. Missing required inputs produce an unavailable result.
Inputs, period and unit
Read the disclosed inputs or source, observation period, bar interval, unit, native currency and scale. A value without its source and as-of context is incomplete; unlike units must not be combined.
Worked example
Illustrative only: For one underlying and 29 August expiry, a chain can show calls and puts at strikes ₹95, ₹100 and ₹105. Mixing another expiry produces a different chain.
What high and low mean
A higher or lower Option chain value is descriptive, not automatically good or bad. Meaning depends on the instrument, comparison period, method and related evidence.
Positive, negative and genuine zero
Positive and negative Option chain values retain the definition shown here. A genuine reported or computed zero is displayed as 0 and is not the same as missing evidence.
Limitations and common mistakes
Option chain may differ by provider definition, observation time, instrument and venue. Common mistakes are dropping units or dates, comparing unlike scopes, and treating a missing value as zero.
Market-specific differences
Contract size, exercise style, expiry, settlement, price unit and trading rules vary across all supported markets. Always use the selected contract specification.
