Strike price

The strike is the contract price at which an option's stated exercise right applies.

Plain-language meaning

The strike is the contract price at which an option's stated exercise right applies.

Why it is useful

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

How it is calculated or sourced

Strike price 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: A call with ₹100 strike gives the stated exercise right at ₹100 under the contract. An underlying price of ₹105 does not change the strike to ₹105.

What high and low mean

A higher or lower Strike price 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 Strike price 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 Strike price 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

Strike price 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.
