anas Bollinger Bands high low

normal bb use normally close in its calculation not considering high and low , and the channel is based on 2 std div , with will present 93% of the close reading with in the band .

my new design will calculate the upper band based on high values , and the lower band based on low values , and the center line on close values
, and 1,65 std will represent 90 % of all reading (high , low , close ) to fall with in the band .


up trend will be considered if close price exceeded the top band lower values (within or outside the band )

down trend will be considered if close price exceeded the lower band higher values (within or outside the band )
