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

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.
Regards
