Historical volatility

Significado en lenguaje sencillo

Historical volatility is annualized population standard deviation of logarithmic observed returns over a stated window and is not implied volatility.

Por qué es útil

Historical volatility 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.

Dónde aparece en XMarketRadar

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

Cómo se calcula o se obtiene

Historical volatility 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.

Entradas, período y unidad

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.

Ejemplo práctico

Illustrative only: a user reviews Historical volatility over a stated 20-bar or FY2026 period, checks the displayed source, unit and as-of date, and keeps an absent field as — rather than guessing 0.

Qué significan alto y bajo

A higher or lower Historical volatility value is descriptive, not automatically good or bad. Meaning depends on the instrument, comparison period, method and related evidence.

Positivo, negativo y cero real

Positive and negative Historical volatility values retain the definition shown here. A genuine reported or computed zero is displayed as 0 and is not the same as missing evidence.

Cuándo no está disponible

Unavailable (—) means Historical volatility 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.

Limitaciones y errores comunes

Historical volatility 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.

Diferencias según el mercado
