Bollinger %B

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.

In TradeXtool

Entry: Bollinger %B crosses above 100.

Watch out

Price outside the band is not rare and not automatically a reversal. In a strong trend it stays there for many candles.
