RE: [amibroker] plotshapes changes array?

["Bob Jagow" <bjagow@xxxxxxxxxxxxx>]

Don't you want the current bar to be the longest of the 4 bars?
If so, use WR4 = (H - L) > Ref(HHV(H-L,3),-1);

Also, replace IIf (WR4 = 1.... by IIf (WR4 == 1....

Hi,

I am fighting with the usage of plotshapes.

My goal is to highlight widerange bars (WR4) on a chart. WR4 is true if
1 and not true if -1. The formula seems to calculate everything
correctly as cross checked within exploration and addcolumns. However,
when trying to plot this with the plotshapes command on top of the bar,
it will change the WR4 value to 1 and plot it on every single bar. I got
2 version of the plotshape command in there for you to look at. Any help
would be greatly appreciated.

Anthony

// WR4 show me //

D1 = H-L;
D2 = Ref(H,-1)-Ref(L,-1);
D3 = Ref(H,-2)-Ref(L,-2);
D4 = Ref(H,-3)-Ref(L,-3);

WR4 = 0;

WR4 = IIf(D1 > (D2 OR D3 OR D4),1,-1);

//IIf (WR4 = 1,(PlotShapes( shapeSmallSquare, colorYellow, 0, H * 1.03
)),PlotShapes(shapeNone,colorGreen));
//PlotShapes( IIf( WR4 > 0, shapeSmallSquare, shapeNone ), colorYellow,
0, H * 1.03);

Filter = WR4;

AddColumn( D1, "D1", 1.4 );
AddColumn( D2, "D2", 1.4 );
AddColumn( D3, "D3", 1.4 );
AddColumn( D4, "D4", 1.4 );
AddColumn( WR4, "WR4", 1.4 );
