[amibroker] Re: How to plot a "shape" at a specific date - Param problem

Here is the code. It works ok but there is one problem:

when you go to "parameters" window and change the date the arrows
will disappear from the screen. To make them visible again you have
to open the formula in the editor and click on "apply indicator"
button. Any solution to this, anyone?

BTW, if you hit the "reset" button in the parameters window it will
put the arrows on the screen at the default date as specified in the
formula (2005-03-07).


Title = Name() + "  " + Interval(format=2) + "  " + Date();
Plot( Close, "", 42, 64 );
GraphXSpace = 4;

Date_Num = ParamDate( "Date", "2005-03-07", 0);

PlotShapes(shapeDownArrow * (DateNum()==Date_Num), colorRed, 0, H,
-15);
PlotShapes(shapeUpArrow *   (DateNum()==Date_Num), colorBrightGreen,
0, L, -15);
