Multi-Color buffer line - Need more clarification

[selnomeria]

In this article - https://www.mql5.com/en/articles/135

there is not writen, how color-buffers are assigned to specific buffer.

for example:

   SetIndexBuffer(0,buffer_line1,INDICATOR_DATA);

PlotIndexSetInteger(0,PLOT_LINE_COLOR,0, clrGreen); PlotIndexSetInteger(0,PLOT_LINE_COLOR,1, clrRed);

   SetIndexBuffer(1,buffer_line2,INDICATOR_DATA);

PlotIndexSetInteger(1,PLOT_LINE_COLOR,0, clrGreen); PlotIndexSetInteger(1,PLOT_LINE_COLOR,1, clrRed);

   SetIndexBuffer(4, color_buffer,INDICATOR_COLOR_INDEX);

My question is , when we set values in the loop:

color_buffer[i] = 1;

which buffer-line color is changed?  1st or 2nd buffer?

how to refer the color-buffer to specific data-buffer?

The way you wrote it, none of your lines will be colored line

Check the link in your post

I have read and that's why I have asked...  I couldnt find out with those examples...  please tell me how to do that, 

the colorbuffer-index should be the next index of the desired buffer-index???

[selnomeria]

have I to add only this?

PlotIndexSetInteger(indexx,PLOT_DRAW_TYPE, DRAW_COLOR_LINE  );

Colored lines always go in pairs

Something like this

 SetIndexBuffer(0,buffer_line1,INDICATOR_DATA);
 SetIndexBuffer(1,buffer_line1colors,INDICATOR_COLOR_INDEX);
 SetIndexBuffer(2,buffer_line2,INDICATOR_DATA);
 SetIndexBuffer(3,buffer_line2colors,INDICATOR_COLOR_INDEX);


 SetIndexBuffer(nn  ,buffer_line(nn),INDICATOR_DATA);
 SetIndexBuffer(nn+1,buffer_line(nn)colors,INDICATOR_COLOR_INDEX);

You can not have one colors buffer for multiple color lines

THANKS! now i understand. THAT SHOULD BE WRITTEN IN DOCS, what you say.

Are you sure it is not ?

Hello, thanks a lots

I'wited code that drow standard deviation index in multicolor (red when up, green when down) and other two indicator that drow move with different period time.

Here there a mql4 example of couple of my custom indicator (standardeviation with move and color as alert and new saratoga indicator), When i try to write standard deiation multicolored index with 2 move index

i'find a lot of matter.

I'think that mql5 manual are made only for mega expert, or simply it eritted in wrong mode!

here is a side of code in mql5. The result is  no multicolor in stddev

int OnInit()

{  

   Hstd                = iStdDev(_Symbol, _Period, SDPrd, 0, MODE_SMA, PRICE_CLOSE);  // deviazione standard a SDPrd

   min_rates_total     = int(MathMax((SDPrd + 1), movNormale));

//--- indicator buffers mapping

   SetIndexBuffer(0, STD, INDICATOR_DATA);

   SetIndexBuffer(1, StdMoveCorta, INDICATOR_DATA);

   SetIndexBuffer(2, StdMoveNormale, INDICATOR_DATA);

   

   s = "Tiz Std(" +  DoubleToString(SDPrd) + ")";   

   PlotIndexSetInteger(0, PLOT_DRAW_TYPE, DRAW_LINE);

   PlotIndexSetInteger(0, PLOT_LINE_STYLE, STYLE_SOLID);

   PlotIndexSetInteger(0, PLOT_LINE_COLOR, clrLime);  

   PlotIndexSetInteger(0, PLOT_LINE_WIDTH, 2);   

   PlotIndexSetInteger(0, PLOT_DRAW_BEGIN, min_rates_total );  

   PlotIndexSetDouble(0, PLOT_EMPTY_VALUE, 0.0);  

   PlotIndexSetString(0, PLOT_LABEL, s);

   if (OKMovCorta){

      s = "Tiz StdMov(" + movCorta + ")"; //      metto prima l'ombra.... per favorire la visualizzazione....

      PlotIndexSetInteger(1, PLOT_DRAW_TYPE, DRAW_LINE);

      PlotIndexSetInteger(1, PLOT_LINE_STYLE, STYLE_DOT);

      PlotIndexSetInteger(1, PLOT_LINE_COLOR, clrBlue);

      PlotIndexSetInteger(1, PLOT_LINE_WIDTH, 1);     

      PlotIndexSetInteger(1, PLOT_DRAW_BEGIN, min_rates_total );  

      PlotIndexSetDouble(1, PLOT_EMPTY_VALUE, 0.0);

      PlotIndexSetString(1, PLOT_LABEL, s);   

   }

   if (OKMovNormale){

      s = "Tiz StdMov(" + movNormale + ")"; //      metto prima l'ombra.... per favorire la visualizzazione....

      PlotIndexSetInteger(2, PLOT_DRAW_TYPE, DRAW_LINE);

      PlotIndexSetInteger(2, PLOT_LINE_STYLE, STYLE_DOT);

      PlotIndexSetInteger(2, PLOT_LINE_COLOR, clrBlack);

      PlotIndexSetInteger(2, PLOT_LINE_WIDTH, 1);     

      PlotIndexSetInteger(2, PLOT_DRAW_BEGIN, min_rates_total );  

      PlotIndexSetDouble(2, PLOT_EMPTY_VALUE, 0.0);

      PlotIndexSetString(2, PLOT_LABEL, s);   

   }

   

   SetIndexBuffer(3, StdColor, INDICATOR_COLOR_INDEX); // serve per indicare il colore fra direzione su e giu       

   

   // si devono indicare i colori dopo la dichiarazione del buffer colori

   PlotIndexSetInteger(0, PLOT_COLOR_INDEXES, 2);  // due colori x l'indice

   PlotIndexSetInteger(0, PLOT_LINE_COLOR, 0, Up);   // colore per su

   PlotIndexSetInteger(0, PLOT_LINE_COLOR, 1, Down); // colore per giù      

   

   IndicatorSetInteger(INDICATOR_DIGITS, 5);   

Yes, of course, in onCalculate side I put this code

      // determino il colore

      if ( STD[k] > STD[k-1] ) // LIME SU

         StdColor[k] = 0; 

      else

         StdColor[k] = 1; 

Someone can help me ? thank you.

      

Here are result in mql5 (last indicator, stddev is of lime color and not in multicolor)
