The ZiBoll Style Indicator is based on special view of the bollinger bands. The bollinger values are computed with the help of a weighted average of the Low’s and of the High’s.
When those MA’s are computed , they where compared with the close to create a Boolean result.
Signals are given by red and blue arrows. (arrows into red and blue circles). Compare with the backtest arrows, it don’t fit. I like to discuss this matter.

add between line 50 and 51 : drawtext(“#dnh#”,barindex,low-2.618*AverageTrueRange[14](close),Dialog,Bold,30) coloured(55,55,255,255)
add also between line 55 and 56 : drawtext(“#upH#”,barindex,low-2.618*AverageTrueRange[14](close),Dialog,Bold,30) coloured(0,255,255,255)
