Super Passband Filter
MLADEN : This is what john Ehlers call "Super Passband Filter" as described in the July 2016 edition of TASC
Some addition by me (mladen) - mainly the calculation count - that count changes the values of the "band" -
Multi symbol and multi Time Frame (interpolated) already supported - 22 prices option - 3 state coloring option (color change on slope-outer band cross or zero line cross)
bands squeezed when price not in trend so an extra level can be added both side the zero line where when bands entered describing no trade zone
