I'm trying to get a moving average of the close values from Heiken Ashi. Here is the code:
Inserted Code
#property indicator_chart_window
#property indicator_buffers 1
#property indicator_color1 Green
double varValue[];
double tmpValue[];
//+------------------------------------------------------------------+
//| Custom indicator initialization function                         |
//+------------------------------------------------------------------+
int init()
  {
//---- indicators
   SetIndexBuffer(0, varValue);
   SetIndexLabel(0,"Diff");
   SetIndexStyle(0,DRAW_LINE);
//----
   return(0);
  }
//+------------------------------------------------------------------+
//| Custom indicator deinitialization function                       |
//+------------------------------------------------------------------+
int deinit()
  {
//----
 
//----
   return(0);
  }
//+------------------------------------------------------------------+
//| Custom indicator iteration function                              |
//+------------------------------------------------------------------+
int start()
  {
   int    counted_bars=IndicatorCounted();
//----
   int limit;
   string dt;
   limit=Bars-counted_bars;
   for(int i=0; i < limit; i++) 
   {
      for (int j=i; j<j-6; j++)
      {
         tmpVaule[i]=iCustom(NULL,0,"HeikenAshi",3,j);
      }
      varValue[i]=iMAOnArray(tmpValue,0,5,0,MODE_SMMA,0);
   }
return(0);
}

The only values I get are 0.00000 on my chart. Can someone show me where I went wrong?

THANKS!

there are some errors in your code: try this one instead:
Inserted Code
#property indicator_chart_window
#property indicator_buffers 1
#property indicator_color1 Green

extern int period=5;

double varValue[];

double sum=0;

int start()
  {
   int    counted_bars=IndicatorCounted();
//----
   int limit;
   if(counted_bars < 0) 
        return(-1);
   if(counted_bars > 0) 
        counted_bars--;
   limit=Bars-counted_bars-1;
   for(int i=limit; i >=0; i--) 
   {
      sum=0;
      for(int j=i+period-1;j>=i; j--)
      {
          sum+=iCustom(NULL,0,"Heiken Ashi",3,j);
      }
      varValue[i]=sum/period;
   }
return(0);
}
it calculates a 5 period moving avarage on HA close values. (current bar and 4 bars before).
if you don't want the current bar to be calculated, but the 5 bars before change the inner loop to this:

for(int j=i+period;j>i; j--)
