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.
rgds, Ed
per = 80;
mm = (H + L) / 2;
x = Cum(1);
lastx = LastValue(x);
selv = SelectedValue(x);
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 - yy);
dll =
abs(L - yy);
dtt = Max(dhh,dll);
wd = SelectedValue(HHV(dtt,per));
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?
