Where price sits inside its Bollinger band, as a percentage.
0 is on the lower band, 100 on the upper, 50 on the middle. Above 100 means price is outside the band.
Worked out by the same code the builder uses, on stored daily candles. Move a setting and the line moves with it. This is what happened, not what will happen.
Entry: Bollinger %B crosses above 100.
Price outside the band is not rare and not automatically a reversal. In a strong trend it stays there for many candles.
