Re: [amibroker] Re: Plotting problem

Lester,

 

Tried the IIF code but got the same results.  It must be my logic but for the life of me I cannot understand why the logic is not stopping the plotting when the conditions are reached.  Instead the logic appears to be saying that in every bar there is a long and short signal which is not the case.  Here's the new code I generated:

 

PivotMALong=MA(Pivot,LongPeriods);

PivotMAShort=MA(Pivot,ShortPeriods);

// Plot Long and short period MA of pivot

Plot( PivotMALong, "PivotLong",ParamColor( "Color1", colorCycle ), ParamStyle("Style1",styleThick) );

Plot( PivotMAShort, "PivotShort",ParamColor( "Color2", colorCycle ), ParamStyle("Style2",styleThick) );

 

// Check for Long or Short Signals

dotlocationLong = L - 3;

dotlocationShort = H + 3;

IIf((C[0] > PivotMALong[0]) AND (C[0] > PivotMAShort[0]) AND (PivotMAShort[0] > PivotMALong[0]),

Plot(dotlocationLong,"Long",ParamColor( "Color3", colorGreen ), ParamStyle("Style3",styleDots | styleNoLine | styleNoLabel)),0);

IIf((C[0] < PivotMALong[0]) AND (C[0] < PivotMAShort[0]) AND (PivotMAShort[0] < PivotMALong[0]),

Plot(dotlocationShort,"Short",ParamColor( "Color4", colorRed ), ParamStyle("Style3",styleDots | styleNoLine | styleNoLabel)),0);

Does the logic make sense to you?

thx,

Freddie

1) Instead of "for" loop use IIF(), it's easier:

2) Use PlotShapes() to plot dots, arrows, etc. on the chart:

http://www.amibroker.com/guide/afl/afl_view.php?id=206

Your code should look something like this:

dotlocationLong = L - 3;
dotlocationShort = H + 3;

// specify variables
PivotMALong = ??;
PivotMAShort = ??;

IIF( ... your conditions here ... );

// plot the main chart
Plot( Close, "", colorBlue, styleCandle );

// plot your shapes
PlotShapes( ... );

/////
Below is an example of the code for PlotShapes. This is just one possible method, there are a few different ways of coding this:

//***START ***//

Title = Name()+" \\c11"+Interval(format=2)+" "+Date()+"\\c-1 C="+C+"\\c11 "+FullName();

Plot(C,"",colorBlue, styleCandle);
Plot(EMA(C,14), "", 32, 1);

Buy =Cross(C, EMA(C,14));
Sell=Cross(EMA(C,14), C);

PlotShapes(shapeUpArrow * Buy, colorGreen, 0, L, -15);
PlotShapes(shapeDownArrow * Sell, colorRed, 0, H, -15);

SetChartOptions(0, chartShowDates); // show Date on X-axis

// to prevent your shapes to move beyond the
// top/bottom of the chart use this:
GraphXSpace = 5;

//***END ***//
