Standard deviation

Significado en lenguaje sencillo

XMarketRadar's chart study uses trailing population standard deviation with divisor N over a complete selected-price window.

Por qué es útil

Standard deviation 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 Standard deviation in Advanced Chart settings, indicator panels, screeners and technical research for the selected listing and bar interval.

Cómo se calcula o se obtiene

XMarketRadar uses the population convention over the complete trailing window: take the square root of the mean squared distance from that window's arithmetic mean, dividing by N rather than N−1.

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 Standard deviation 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 Standard deviation 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 Standard deviation 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 Standard deviation 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

Standard deviation 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

The concept is used across all supported markets, but currency, price scale, session calendar, source field and regulatory definition can differ. XMarketRadar preserves the exact exchange context.
