ZigZag with cumulative volume

  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 );

  }

  Do you have any screenshots of how it should be displayed please? Amibroker and prorealtime don’t share the same graphical capabilities, so I’d like to know how you want it to give you the desired information (cumulative volume) before coding it. Thanks in advance!

  Here is a simple code to make the same thing than MetaStock. The code you submitted use built-in instructions of MetaStock, so I think I have correctly recode it, please make your own tests and give feedbacks!

  zz = ZigZag[9](close) peak = zz<zz[1] and zz[1]>zz[2] tough = zz>zz[1] and zz[1]<zz[2] cumV = cumV[1]+volume if peak then text = cumV/1000 drawtext("#text#K",barindex,cumV+(cumV/20),Dialog,Bold,12) coloured(0,200,0) cumV = 0 color = -1 elsif tough then text = cumV/1000 drawtext("#text#K",barindex,cumV+(cumV/20),Dialog,Bold,12) coloured(200,0,0) cumV = 0 color = 1 endif return cumV coloured by color

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

  zz = ZigZag[9](close)   peak = zz<zz[1] and zz[1]>zz[2] tough = zz>zz[1] and zz[1]<zz[2]   cumV = cumV[1]+volume   if peak then text = cumV/1000 drawtext("#text#K",barindex,cumV+(cumV/20),Dialog,Bold,12) coloured(0,200,0) cumV = 0 color = -1 elsif tough then text = cumV/1000 drawtext("#text#K",barindex,cumV+(cumV/20),Dialog,Bold,12) coloured(200,0,0) cumV = 0 color = 1 endif   return cumV coloured by color

  You’ll find attached a sample screenshot of what we get on chart. I did not add the ZigZag lines on the Volumes, is it necessary? or do you want it too? If it’s ok, I certainly add this in the prorealtime code library.

  You are always of great help Nicolas, Thank you!

  The indicator work only on daily charts. Do you think it is possible to have it for lower timeframes, too?

  It should work on any timeframe. Of course you need instruments with Volumes. The [9] in the first line of code is 9% percent of variation to draw a new zigzag point, so it should be modified for intraday timeframe.

  This indicator seems of interest of many people! How do you use it exactly? Many thanks.

  Hi Nicolas,

  Thanks for your quick respond.

  I’m trying to set up this indicator but it comes up with

  error on lines: 10, 15, 20

  I’m using PRT version   v10.2-1.8.0_45

  Best regards

  Because you’re still with 10.2 and drawing text on charts were not possible with this version.

  Just remove lines 9,10,14 and 15 and it should be OK. Please confirm.

  If you believe that volume is important than this indicator is very helpful.

  The theory is based on R Wyckoff  works and refined by D Weis.

  In the nutshell cumulative volume helps to asses the strength of the ZigZag section which

  is difficult to measure if you looking at the individual volume bars only.

  Your Amazon chart shows exactly the power of this indicator!

  Yes it works thanks.

  It does not change colour on UP/Down moves but this not a problem

  I’ve add Variable to zz function so it is easy to adjust sensitivity of ZigZag

  One more question,

  the cumulative volume count is missing first volume after the top turn

  and first volume after the trough

  Just a question abuot this indicator. Is it possible to create different value for red cumulative volume and green cumulative volume ?

  You have to modify yourself the Up/Down (Positive/Negative) colors of the histogram in the indicator window.

  Right, it’s fixed in this new version of the code:

  zz = ZigZag[9](close) peak = zz<zz[1] and zz[1]>zz[2] tough = zz>zz[1] and zz[1]<zz[2] cumV = cumV+volume if peak then text = cumV/1000 drawtext("#text#K",barindex,cumV+(cumV/20),Dialog,Bold,12) coloured(0,200,0) cumV = Volume color = -1 elsif tough then text = cumV/1000 drawtext("#text#K",barindex,cumV+(cumV/20),Dialog,Bold,12) coloured(200,0,0) cumV = Volume color = 1 endif return cumV coloured by color

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

  zz = ZigZag[9](close)   peak = zz<zz[1] and zz[1]>zz[2] tough = zz>zz[1] and zz[1]<zz[2]   cumV = cumV+volume   if peak then text = cumV/1000 drawtext("#text#K",barindex,cumV+(cumV/20),Dialog,Bold,12) coloured(0,200,0) cumV = Volume color = -1 elsif tough then text = cumV/1000 drawtext("#text#K",barindex,cumV+(cumV/20),Dialog,Bold,12) coloured(200,0,0) cumV = Volume color = 1 endif   return cumV coloured by color
