Hi,

Below is the AFL Code (Amibroker) which I would like to adopt for PRT Charts

The indicator simply calculate and histogram the cumulative volume of each zig-zag turn.

I would greatly appreciate the help here.

I am a long-time client of IG Markets

function SumSince2( condition, array )

{

CumA = Cum( array );

return CumA – ValueWhen( condition, CumA ) + ValueWhen( condition, array ) ;

}

//Plot( Close, “Close”, colorDefault );

Plot( Zig(Close,9), “Zig”, colorBlue, styleThick);

// count bars since last peak or trough

pkb = PeakBars( Close, 9 );

trb = TroughBars( Close, 9 );

// identify peaks

pk = pkb == 1;

tr = trb == 1;

// define Plot color

color = IIf( Ref(pkb < trb,-1), colorRed, colorGreen );

// calculate cumulated volume

cumVolume = SumSince2( pk OR tr, Volume);

Plot( cumVolume, “cumulated Volume”, color, styleHistogram | styleOwnScale, 2 );

dist = ATR(10);

for( i = 0; i < BarCount-1; i++ )

{

if( tr[ i+1 ] ) PlotText( NumToStr(CumVolume[ i ]/1000,1,1) +”k”, i, L[ i ] – dist[i], colorRed );

if( pk[ i+1 ] ) PlotText( NumToStr(CumVolume[ i ]/1000,1,1) +”k”, i, L[ i ] + dist[i], colorgreen );

}
