This is an example of what I think it is you want to do. See lower part: shading. Note: the background of the chart used is black.

per = 80;
mm = (
H + L) / 2

x =

lastx =
LastValue

selv =
SelectedValue

aaa =
LinRegIntercept
(mm, per);
bbb =
LinRegSlope
(mm, per);

daa =
SelectedValue(ValueWhen(x, aaa, 1

dbb =
SelectedValue(ValueWhen(x, bbb, 1

xx =
IIf(x > selv - per AND x <= selv, x - (selv - per),Null

yy = daa + dbb * xx;

dhh =
abs(H

abs(L

dtt =

wd =
SelectedValue(HHV

Buy = Ref(L,-1) == Ref(yy - wd, -1) AND Ref(selv == x,-1

BuyPrice = O

Short = Ref(H,-1) == Ref(yy + wd, -1) AND Ref(selv == x,-1

ShortPrice = O

Plot(C,"",colorWhite,64

Plot(yy, "LinReg", colorBlue
);
Plot(yy + wd, "Upper Boundary", colorRed, 4

Plot(yy - wd, "Lower Boundary", colorBrightGreen, 4
);

// shading

Plot(yy - wd, "Lower Boundary", colorBlack, 16384

Plot(yy + wd, "Lower Boundary", colorWhite, 16384

PlotShapes(IIf(Buy,shapeUpArrow,0),colorWhite, layer = 0, yposition = BuyPrice, offset = 0
);
PlotShapes(IIf(Short,shapeHollowDownArrow,0),colorLightBlue, layer = 0, yposition = ShortPrice, offset = 0 );

Subject: [amibroker] Area between

Is it possible to produce a code that draws stylehistogram or stylearea only between two curves?  My thought is a bit fuzzy, but it seems if the Y axis could be converted into an array then it might be possible to utilize stylenodraw in sections where the area should not be filled in.  Sound crazy?  If not, any thoughts about how this might be done?
