The Bollinger pct_b (%b) indicator shows the closing price in relation to the upper and lower band. It will exceed one when the last price is above the upper band or will fall beneath zero when the last price is below the lower band.

A reading of 1,1 tells us that we are 10 percent of the bandwidth above the upper band. A reading of -0,15 means that the last price is 15 percent of the band width below the lower band.
