Expiry

Plain-language meaning

Expiry is the date or session when a derivative contract expires under its contract specification.

Why it is useful

Expiry 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 Expiry in Futures, Option Chain, Options Screener and derivative study tables for a selected underlying and contract.

How it is calculated or sourced

Expiry is provider- or exchange-reported contract/market data for a stated instrument and observation time; XMarketRadar does not infer a missing value from nearby rows.

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: Two otherwise similar options expiring 29 August and 26 September have different time remaining and prices; they must not share one expiry label.

What high and low mean

A higher or lower Expiry 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 Expiry values retain the definition shown here. A genuine reported or computed zero is displayed as 0 and is not the same as missing evidence.

When it is unavailable

Unavailable (—) means Expiry is absent, unsupported, stale under the screen's rules or not computable from verified inputs. It must never be converted to zero or a neutral signal.

Limitations and common mistakes

Expiry 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.
