per = 10;
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;

detrend = mm - yy;
wd = SelectedValue(HHV(abs(detrend),per));

Plot(yy, "LinReg", colorBlue );
Plot(yy + wd, "Upper Boundary", colorRed );
Plot(yy - wd, "Lower Boundary", colorBrightGreen );

Plot(C,"",colorwhite,64);
