VW %BB +

Volume weighted %BB Based on Closing price (green line)
%BB of 50 period ema of the 20 period volume weighted moving average at each point (blue)

difference of %BB green - %bb Blue shading around mid-band (ie width between two in band terms)

added an additional line which is the sum of the absolute distance from mid-band of the ema + top half of bandwidth difference

הערות שחרור:

added open / close position + shading within %BB. now distance between closing / open price and 50 period ema of volume weighted average is measured in band-width and split across midband. (intepret it as distance from closing to ema but in %bb terms)
