What do you mean by "set the start date" for an
indicator? How are you doing this? What else is in your code?
Are you using functions such as SelectedValue(), etc.?

Subject: SV: [amibroker] PlotShapes
problem.
Hello,
I am most grateful, this solved problem 2. Strangely
enough, it only
partially resolved problem number 1. If I set the startdate
to 2000-03-07,
when our market topped out, and zoom in, the arrows then
disappear when I
reach 2003-03 as the left boundary in the chart. Very
strange.
Also, still no arrows in weekly or monthly charts using my
calculation. This
however is only a minor issue.
What I would like to
achieve now is that the arrows do not disappear when I
zoom in.
I thank
you very much for the assistance provided so far.
Best regards /
JM

Re: [amibroker] PlotShapes problem.
Jan
Check out the Plotshapes
in the Help file, then try this.
MA1 = EMA(C,10);
MA2 = EMA(C,
30);
Plot(C,"", 16,64);
Plot(MA1,"", 17, 1);
Plot(MA2,"",
18,1);
XUP = Cross(MA1,MA2);
XDN =
Cross(MA2,MA1);
PlotShapes( IIf(XUP,shapeUpArrow,Null),colorGreen, 0,
L, -20); // plots
green arrow in default layer (0), 20 pixels below the
Low
PlotShapes( IIf(XUP,shapeUpArrow,Null),colorLime, 0, MA2, -35); //
plots
lime arrow in default layer (0), 35 pixels below the MA2
value
PlotShapes( IIf(XUP,shapeDownArrow,Null),colorRed, 2, H, -45); //
plots
red arrow in Daily chart layer (2), 45 pixels above the
High
PlotShapes( IIf(XUP,shapeDownArrow,Null),colorPink, 3, H, -35); //
plots
pink arrow in weekly chart layer (3), 35 pixels above the
High
Works for me back to 2000 whether I am zoomed in or out, scroll or
not.
