Hi all,

I try to get values about an indicator called MACDMomentum. 

I download it from the mql5.com. 

It has values MACD (histogram), Signal (yellow line), Momentum (red line).

I try to get its values for my EA. However, I don't know how I get them.

MACDMomentum

The indicator code's is as follows;

//--- indicator settings
#property  indicator_separate_window
#property  indicator_buffers 4
#property  indicator_color1  Gray// Silver
#property  indicator_color2  Yellow
#property  indicator_color3  White// Silver
#property  indicator_color4 Red // Magenta



#property  indicator_width1  2
//--- indicator parameters
input int InpFastEMA=12;   
input int InpSlowEMA=26;   
input int InpSignalSMA=9;  
input int smooth = 3;
//--- indicator buffers
double    ExtMacdBuffer[];
double    ExtSignalBuffer[];
double    Mom[];
double    Mom_smooth[];
//--- right input parameters flag
bool      ExtParameters=false;

//+------------------------------------------------------------------+
//| Custom indicator initialization function                         |

int OnInit(void)
  {
   IndicatorDigits(Digits+1);
//--- drawing settings
   SetIndexStyle(0,DRAW_HISTOGRAM);
   SetIndexStyle(1,DRAW_LINE);
   SetIndexDrawBegin(1,InpSignalSMA);
//--- indicator buffers mapping
   SetIndexBuffer(0,ExtMacdBuffer);
   SetIndexBuffer(1,ExtSignalBuffer);
//--- name for DataWindow and indicator subwindow label
   IndicatorShortName("MACD("+IntegerToString(InpFastEMA)+","+IntegerToString(InpSlowEMA)+","+IntegerToString(InpSignalSMA)+")");
   SetIndexLabel(0,"MACD");
   SetIndexLabel(1,"Signal");
//--- check for input parameters
 
    SetIndexBuffer(2,Mom );
    SetIndexStyle(2,DRAW_LINE,0,1);

     SetIndexBuffer(3,Mom_smooth );
    SetIndexStyle(3,DRAW_LINE,0,3);

   if(InpFastEMA<=1 || InpSlowEMA<=1 || InpSignalSMA<=1 || InpFastEMA>=InpSlowEMA)
     {
      Print("Wrong input parameters");
      ExtParameters=false;
      return(INIT_FAILED);
     }
   else
      ExtParameters=true;
//--- initialization done
   return(INIT_SUCCEEDED);
  }

   if(prev_calculated==0)     limit = rates_total- 3000;
   if(prev_calculated>0)     limit--;
//--- macd counted in the 1-st buffer
   for(i=limit; i>=0; i--)     ExtMacdBuffer[i]=iMA(NULL,0,InpFastEMA,0,MODE_EMA,PRICE_CLOSE,i)-
                               iMA(NULL,0,InpSlowEMA,0,MODE_EMA,PRICE_CLOSE,i);
//--- signal line counted in the 2-nd buffer
  // SimpleMAOnBuffer(rates_total,prev_calculated,0,InpSignalSMA,ExtMacdBuffer,ExtSignalBuffer);
    for(i=limit; i>=0; i--) ExtSignalBuffer[i] =  iMAOnArray(ExtMacdBuffer,0,InpSignalSMA,0,0,i);


  for(i=limit; i>=0; i--) Mom[i] = ExtMacdBuffer[i] - ExtMacdBuffer[i+10];
  for(i=limit; i>=0; i--) Mom_smooth[i] = iMAOnArray(Mom,0,smooth,0,0,i);


//--- done
   return(rates_total);
  }
//+---------------------

Can ı get values of MACD, Signal and momentum bu using iCustom()? I don't understand exactly.

Best.
