Color the Relative Volume Histogram

  Hi, Some how I cannot manage to color the histogram of the intraday Relative Volume indicator by Nicolas below, into blue for positive and red for negative (attached picture).

  Does anybody know which line must be added to the code for this?

   

   

  Intraday Relative Volume

  //Relative Volume indicator by Nicolas Period = 21 //X days averaging period intraindex = intradaybarindex $ivol[intraindex] = volume $gvol[barindex] = volume $gintraindex[barindex] = intraindex count = 0 sum = 0 for i = barindex downto 0 do if $gintraindex[i]=intraindex then //found same intraday bar sum=sum+$gvol[i] count=count+1 endif if count=period then break endif next avg = sum/period rvol = $ivol[intraindex] / avg return rvol style(histogram)//$ivol[intraindex], avg coloured(0,0,0)

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26

  //Relative Volume indicator by Nicolas   Period = 21 //X days averaging period intraindex = intradaybarindex $ivol[intraindex] = volume $gvol[barindex] = volume $gintraindex[barindex] = intraindex count = 0 sum = 0 for i = barindex downto 0 do if $gintraindex[i]=intraindex then //found same intraday bar sum=sum+$gvol[i] count=count+1 endif if count=period then break endif next avg = sum/period rvol = $ivol[intraindex] / avg return rvol style(histogram)//$ivol[intraindex], avg coloured(0,0,0)

  Hi Marcel

  The values of the indicator are always greater than zero (no negative values) so you can only set the color of the positive values manually.

  Here is the code to color the histogram:

  Relative Volume Histogram

  //Relative Volume indicator by Nicolas Period = 21 //X days averaging period intraindex = intradaybarindex $ivol[intraindex] = volume $gvol[barindex] = volume $gintraindex[barindex] = intraindex count = 0 sum = 0 for i = barindex downto 0 do if $gintraindex[i]=intraindex then //found same intraday bar sum=sum+$gvol[i] count=count+1 endif if count=period then break endif next avg = sum/period rvol = $ivol[intraindex] / avg If rvol>rvol[1] then R=0 G=255 B=0 ElsIf rvol<rvol[1] then R=255 G=0 B=0 EndIf return rvol style(histogram)Coloured(R,G,B)//$ivol[intraindex], avg coloured(0,0,0)

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37

  //Relative Volume indicator by Nicolas Period = 21 //X days averaging period intraindex = intradaybarindex $ivol[intraindex] = volume $gvol[barindex] = volume $gintraindex[barindex] = intraindex count = 0 sum = 0 for i = barindex downto 0 do if $gintraindex[i]=intraindex then //found same intraday bar sum=sum+$gvol[i] count=count+1 endif if count=period then break endif next avg = sum/period rvol = $ivol[intraindex] / avg   If rvol>rvol[1] then R=0 G=255 B=0 ElsIf rvol<rvol[1] then R=255 G=0 B=0 EndIf return rvol style(histogram)Coloured(R,G,B)//$ivol[intraindex], avg coloured(0,0,0)

  into blue for positive and red for negative 🙂

  Thanks JS,

  I have adjusted your idea for the code slightly to my original idea, so that the colors now correspond to the colors of the candles. This works a bit easier for me because I have built a screener that selects American stocks with RVol >2.

  Hi,

  Here’s the next hurdle.

  It appears that the horizontal line (image) is not held by the indicator as an added indicator or loose line.

  This means that every time I open the graph the line has disappeared.

  Does anyone know how I can add a solid horizontal line (at 1.5) to the indicator?

  //Relative Volume indicator by Nicolas Period = 21 //X days averaging period intraindex = intradaybarindex $ivol[intraindex] = volume $gvol[barindex] = volume $gintraindex[barindex] = intraindex count = 0 sum = 0 for i = barindex downto 0 do if $gintraindex[i]=intraindex then //found same intraday bar sum=sum+$gvol[i] count=count+1 endif if count=period then break endif next avg = sum/period rvol = $ivol[intraindex] / avg If open>close then //If rvol>rvol[1] then R=204 G=51 B=0 ElsIf open<close then //ElsIf rvol<rvol[1] then R=0 G=51 B=153 EndIf return rvol style(histogram)Coloured(R,G,B)//$ivol[intraindex], avg coloured(0,0,0)

  Hi Marcel,

  If you only want a permanent horizontal line in the indicator, you can add the following line in your code (before “Return”):

  DrawHLine(1.5) Coloured(“Red”)
