Applying iRSIOnArray() on custom time-series [mql4]

[Pertechnetat]

Dear all,

I'm struggling with a presumably simple task: My custom indicator calculates and plots an indicator line in a window below the chart. Of course, this involves the use of buffers etc. This works as intended. However, now I want to apply the iRSIOnArray() to this custom time-series,that is stored inside the buffer. However, I'm just not getting it to plot or even display values via Comment(). I have my programming background mostly in python and I'm sure I'm missing something in the data-handling. Any help would be very much appreciated! :)

#property indicator_separate_window
#property indicator_buffers 2
#property indicator_color1 clrBlack
#property indicator_color2 clrBlack
//#property indicator_minimum    -2
//#property indicator_maximum    2
#property indicator_level1     0
#property indicator_level2     1
#property indicator_level3     -1
#property indicator_level4     2
#property indicator_level5     -2
#property indicator_levelcolor clrBlack
#property indicator_levelstyle STYLE_SOLID
extern int       barsToProcess=100;
double ExtMapBuffer1[1000];
double indc[1000];
double result;

int init()
  {

   SetIndexStyle(0,DRAW_LINE);
   SetIndexBuffer(0,ExtMapBuffer1);
   ArrayInitialize(indc,0);
   return(0);
  }

int deinit()
  {

   return(0);
  }

int start()
  {
   int counted_bars=IndicatorCounted();

   for(int i=0; i<Bars; i++)
     {


      //Some calculation here, returns result

     
      ExtMapBuffer1[i]=result;   //works and plots properly
      //ArraySetAsSeries(ExtMapBuffer1,true);
      indc[i]=iRSIOnArray(ExtMapBuffer1,0,14,0);  //does not work. Problem with buffer/array/dtyp
     }
   
   return(0);
  }

Create a buffer for the RSI OnArray.

Fill the first buffer BEFORE trying to do the  RSI OnArray.
