[amibroker] can't draw trading arrows

["reinsley" <reinsley@xxxxxxxx>]

Good morning forum,

I'am a newcomer into the Ami world and this is my first post in this
forum.

I'am drowned into the faq, help, forum etc.

An example coming from "How to use drag-and-drop charting interface"
help, gives me problems.

I can't draw trading arrows.

The original :
Buy = Cross(MACD(), Signal() );
Sell = Cross(Signal(), MACD() );

pricefield = ParamField("Price Field", 2);
Color = ParamColor("color",colorRed);
style = ParamStyle("style",styleLine,maskAll);
arrows = ParamToggle("Display arrows", "No|Yes",0);
Plot(pricefield,"My Indicator",Color,style);
if(arrows)
{
 
PlotShapes(Buy*shapeUpArrow+Sell*shapeDownArrow,IIf(Buy,colorGreen,colorRed)
);
}

I modified two things :

Buy = Cross(MACD(), Signal() );
Sell = Cross(Signal(), MACD() );
Short = Cross(Signal(), MACD() );
Cover = Cross(MACD(), Signal() );

and

{
PlotShapes(Buy*shapeUpArrow+Cover*shapeUpArrow+Sell*shapeDownArrow+Short*shapeDownArrow,IIf(Buy+Cover,colorGreen,colorRed)
);
}

In Automatic Analysis Settings I don't see in the trade tab, Short nor
Cover. Is it normal or an issue ?

The Properties parameters  Axes & Grid tab is set to show trading
arrows Yes.

Thank you for your help

Reinsley
