Bollinger %B Technical Analysis & Bollinger %B Trading Signals
Engineered & Built by John Bollinger
Percent B Comes from Bollinger Bands Calculation.
It Is an Oscillator with Three Lines: 0, 50, and 100
- 0 represents lower Band
- 50 represents middle Band
- 100 represents upper Band
Percent B fluctuates within these three defined boundaries, illustrating the price's position relative to the three Bollinger Bands.

%b indicator
If the price tests or touches the top band, the oscillator reaches 100: if the price goes above the top band, the oscillator goes to +100.
When price hits the lower band, the oscillator reaches 0. If price drops below that band, the indicator goes to -1.
when the marketplace price touches/assessments the middle band then the oscillator indicator could be at 50.
Calculation
Percent B is calculated as Price Close minus Lower Band times 100.
Upper Band - Lower Band
