[amibroker] Mark Peaks

[directaim]

Using:

PvtPeak= Peak(H, 5, 1);
Plot(PvtPeak,"Peak", colorRed, styleLine);

a line is plotted from all Peaks.

But, using:

PvtPeak= Peak(H, 5, 1);
PlotShapes(shapeCircle*PvtPeak, colorRed, 0, H, 20) ;

no shape appears,
error arrows do appear.

Can a change be made 
to make shapes appear?
