Bollinger Bands

సరళమైన అర్థం

Bollinger Bands place configurable population-standard-deviation bands around a moving average; XMarketRadar's standard setting is 20 periods and 2 deviations.

ఇది ఎందుకు ఉపయోగకరం

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.

XMarketRadarలో ఎక్కడ కనిపిస్తుంది

Look for Bollinger Bands in Advanced Chart settings, indicator panels, screeners and technical research for the selected listing and bar interval.

ఎలా లెక్కిస్తారు లేదా మూలం

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.

ఇన్‌పుట్లు, కాలం మరియు యూనిట్

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.

ప్రాయోగిక ఉదాహరణ

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.

ఎక్కువ మరియు తక్కువ అర్థం

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.

ధన, ఋణ మరియు నిజమైన సున్నా

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.

ఎప్పుడు అందుబాటులో ఉండదు

Unavailable (—) means Bollinger Bands 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.

పరిమితులు మరియు సాధారణ తప్పులు

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.

మార్కెట్ ప్రత్యేక తేడాలు

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.
