Re: [amibroker] Assist required on below code...

no problem.

when you are new to Amibroker this code is probably tough to understand, and I admit it is a bit over the top. Parts of the code I added to add a white color to the pivot when it is still not confirmed and therefor may disappear when new data comes in.

What I always do is put things like this in the code

"pxn0: " + writeval(pxn0)

"tx1: " + writeval(tx1)

and then put your mouse on a certain bar and look at the interpretation window to see what the values are of the arrays. Then you can more easily understand what is happening inside the arrays

but if you just want the pivots then these 2 lines do all the work:

// complete pivots
pk = H > Ref( HHV( H, leftStrength ), -1 ) AND Ref( HHV( H, rightStrength ), rightStrength ) <= H;
tr = L < Ref( LLV( L, leftStrength ), -1 ) AND Ref( LLV( L, rightStrength ), rightStrength ) >= L;

Thanks Edward for sharing your code. I will study the code below, as a new Amibroker user, the code you have provided is a great learning tool.

you can best do this while constructing the fractal pivot, see fractal pivots I use:

x = BarIndex();
Lx = LastValue( x );

rightStrength = Param( "Fractal Pivot Right side Strength", 2, 0, 50, 1 );
leftStrength = Param( "Fractal Pivot Left side Strength", 2, 0, 50, 1 );

// complete pivots
pk = H > Ref( HHV( H, leftStrength ), -1 ) AND Ref( HHV( H, rightStrength ), rightStrength ) <= H;
tr = L < Ref( LLV( L, leftStrength ), -1 ) AND Ref( LLV( L, rightStrength ), rightStrength ) >= L;

// left sided pivots
pkn = H > Ref( HHV( H, ( leftStrength ) ), -1 );
trn = L < Ref( LLV( L, ( leftStrength ) ), -1 );

for( i = 0; i < 3; i++ )
{
    VarSet( "px" + i, ValueWhen( pk, x, i ) );
    VarSet( "tx" + i, ValueWhen( tr, x, i ) );
    VarSet( "ph" + i, ValueWhen( pk, H, i ) );
    VarSet( "tl" + i, ValueWhen( tr, L, i ) );
    VarSet( "pxn" + i, ValueWhen( pkn, x, i ) );
    VarSet( "txn" + i, ValueWhen( trn, x, i ) );
}

GraphXSpace = 5;
SetChartBkColor( colorBlack );
SetChartOptions( 0, chartShowDates );
SetBarFillColor( IIf( C > O, colorGreen, IIf( C <= O, colorRed, colorLightGrey ) ) );
Plot( C, "Last", IIf( C > O, colorDarkGreen, IIf( C <= O, colorDarkRed, colorLightGrey ) ), 64, null, null, 0, 0, 1 );
PlotShapes( shapeSmallCircle*tr, IIf( Lx - ValueWhen( tr, x ) >= rightStrength OR pxn0 > tx1, ColorRGB( 0, 100, 0 ), colorWhite ), 0, L, -10 );
PlotShapes( shapeSmallCircle*pk, IIf( Lx - ValueWhen( pk, x ) >= rightStrength OR txn0 > px1, ColorRGB( 255, 0, 0 ), colorWhite ), 0, H, 10 );

Subject: [amibroker] Assist required on below code...

I'm using the below code and was wondering if anyone can assist in correcting or showing me where I'm going wrong…

The idea is the place the green dot on the middle bar at the high on the attached graphic

_Section_Begin("TestBARDot");

UpFractalBW = IIf(((Ref(H,-1) >= Ref(H, -2)) AND (Ref(H,-1) >= H)),True,False);

Buy = UpFractalBW;

Shape = Buy * shapeCircle;

Plot( Close, "Price", colorBlack, stylebar );

PlotShapes( shape, IIf(Buy , colorGreen, 0 ), 0, IIf( Buy, High, Low ),0 );

GraphXSpace = 5;

_SECTION_END();

I know it's the UpFractalBW array that is assigned the true value one bar late…how to I place the true value in the array at Ref(H,1) ?

Any assistance would be greatly appreciated!
