[amibroker] Re: PlotShapes - help please

["c_r_south" <colin_south@xxxxxxx>]

Thanks Bill,

Here is one piece of code that uses PlotShapes and produces nothing on the chart.


SetChartOptions(0,chartShowArrows);  //I put this to try to unhide arrows!

_N("_DefaultName()");
periods = Param( "Periods", 8, 1, 200, 1 );
Ksmooth = Param( "%K avg", 3, 1, 200, 1 );
Dsmooth = Param( "%D avg", 3, 1, 200, 1 );
upperStochLevel = Param("Stoch High",80,50,95,1);
lowerStochLevel = Param("Stoch Low",20,5,50,1);
fastLine = StochK( periods , Ksmooth);
slowLine = StochD( periods , Ksmooth, DSmooth );
Plot( fastLine, "", ParamColor( "KColor", colorCycle ), ParamStyle("KStyle") );

Plot(slowLine , "", ParamColor( "DColor", colorCycle ), ParamStyle("DStyle") );
Buy = IIf((Ref(fastLine,-1) <= lowerStochLevel) AND Cross(fastLine,slowLine),1,0);
Sell = IIf((Ref(fastLine,-1) >= upperStochLevel) AND Cross(slowLine,fastLine),1,0);

shape = Buy * shapeUpArrow + Sell * shapeDownArrow;
PlotShapes( shape, IIf( Buy, colorGreen, colorRed ), 0, IIf( Buy, fastLine*0.99, fastLine*1.01 ) 
);
GraphXSpace = 10;
AlertIf(Buy,"SOUND C:\\PROGRAM FILES\\AMIBROKER\\ShortHowl.WAV", "Buy"+FullName
());
AlertIf(Sell,"SOUND C:\\PROGRAM FILES\\AMIBROKER\\RevShortHowl.WAV", 
"Sell"+FullName());
/*
"shape = "+WriteVal(shape,4.0);
"sell = "+WriteVal(Sell,4.0);
"buy = "+WriteVal(Buy,4.0);
"fastLine = "+WriteVal(fastline,4.1);
"Ref(fastLine) = "+WriteVal(Ref(fastline,-1));
*/


Stepping along the stochastic plot with the cursor, one can see where shape changes from 
1 to 2 on buy and sell signals, but I get no arrows. This statement is true for any piece of 
code which has PlotShapes.
Regards,
Colin
