iMA() in EA is not the same like in Custom indicator

Hello,

I programmed a simple EA and need the values out of the Custome Indicator. I dont know how to get those values from the Custome Indicator into the EA so I calculate them in EA programm too.

I started MT4 twice and compared the print() in both windows and they seemed not to be the same. The Indicator doesen`t refresh as much than the EA does. Also the iMA() in the EA goes up to 88 or drops to zero the other don`t (max was 82 while i observed it). The IndicatorCounted(); in EA is -1 and in Indicator about 1700.

I also figured out i have to write Print("middle2=",iMA(NULL, 0, period, 0, MODE_SMA, PRICE_TYPICAL, x)); and not Print("middle2=",middle2, x)); in the EA. Which means I couldnt refer to the definition of middle2 in the EA.

This is the Code of the EA:

double upper[], middle[], lower[], checkpointa[], checkpointb[];
extern int period = 100;
int init()
  {
//----
   
//----
   return(0);
  }
//+------------------------------------------------------------------+
//| expert deinitialization function                                 |
//+------------------------------------------------------------------+
int deinit()
  {
//----
   
//----
   return(0);
  }
//+------------------------------------------------------------------+
//| expert start function                                            |
//+------------------------------------------------------------------+

   int start() 
{  
   int limit;
   int counted_bars=IndicatorCounted();
   if(counted_bars>0) counted_bars--;
      
   
   limit=Bars-counted_bars;
   
   double avg;
  
   for(int x=0; x<limit; x++) 
   {
      middle[x] = iMA(NULL, 0, period, 0, MODE_SMA, PRICE_TYPICAL, x);
      avg  = findAvg(period, x);
      upper[x] = middle[x] + avg;
      lower[x] = middle[x] - avg;
      checkpointa[x] = upper[x]+0.07;
      checkpointb[x] = lower[x]-0.07; 
     
    // Print("indicator=",counted_bars);
    Print("middle2=",iMA(NULL, 0, period, 0, MODE_SMA, PRICE_TYPICAL, x));
    //Print("checkpointa=",checkpointa[x]);
    //Print("upper=",upper[x]);
    //Print("avg=",avg);
    }         
   return(0);
  }
//+------------------------------------------------------------------+


   double findAvg(int period, int shift) {
      double sum=0;
      for (int x=shift;x<(shift+period);x++) {     
         sum += High[x]-Low[x];
      }
      sum = sum/period;
      return (sum);
   }

And this is the Custome Indicator:
