Bollinger %B
Bollinger %B locates the close within or beyond the bands: (close − lower band) divided by (upper band − lower band).
Plain-language meaning
Bollinger %B locates the close within or beyond the bands: (close − lower band) divided by (upper band − lower band).
Why it is useful
Bollinger %B 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 Bollinger %B in Advanced Chart settings, indicator panels, screeners and technical research for the selected listing and bar interval.
How it is calculated or sourced
Calculate %B = (close − lower band) / (upper band − lower band). It is unavailable when the band has zero width, because division by zero would not describe a position.
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: With lower ₹92, upper ₹108 and close ₹106, %B = (106−92)/(108−92) = 0.875. A close at ₹110 would produce 1.125, showing it is above the upper band.
What high and low mean
A higher or lower Bollinger %B 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 Bollinger %B values retain the definition shown here. A genuine reported or computed zero is displayed as 0 and is not the same as missing evidence.
Limitations and common mistakes
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.
Market-specific differences
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.
