Significado en lenguaje sencillo
Bollinger Bands place configurable population-standard-deviation bands around a moving average; XMarketRadar's standard setting is 20 periods and 2 deviations.
Por qué es útil
Bollinger Bands 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 Bollinger Bands in Advanced Chart settings, indicator panels, screeners and technical research for the selected listing and bar interval.
Cómo se calcula o se obtiene
For the standard XMarketRadar setting, calculate the 20-close SMA, calculate trailing population standard deviation using divisor N, then set upper = SMA + 2×deviation and lower = SMA − 2×deviation. A complete 20-bar window is required.
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: With a 20-period SMA of ₹100, population standard deviation ₹4 and multiplier 2, the middle band is ₹100, lower band ₹92 and upper band ₹108. A close of ₹106 is inside the bands and does not by itself predict the next move.
Qué significan alto y bajo
A higher or lower Bollinger Bands 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 Bollinger Bands values retain the definition shown here. A genuine reported or computed zero is displayed as 0 and is not the same as missing evidence.
Limitaciones y errores comunes
Settings, warm-up history, adjusted-price basis and smoothing convention materially change results. Do not compare differently configured indicators as if identical. Partial bars and corporate-action discontinuities can create misleading moves.
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.
