Rebuild TrailingStop problem "Freezing while loop"

[noSkill06s]

The Algorithm of the Trailingstop only Long Example:

My Try:

for(int i=0;i<limit;i++){

   double currentShortMA=iMA(NULL,0,7,0,MODE_EMA,PRICE_CLOSE,i+1);
   double currentLongMA=iMA(NULL,0,13,0,MODE_EMA,PRICE_CLOSE,i+1);   
   double previousShortMA=iMA(NULL,0,7,0,MODE_EMA,PRICE_CLOSE,i+2);
   double previousLongMA=iMA(NULL,0,13,0,MODE_EMA,PRICE_CLOSE,i+2);

   if(previousShortMA<previousLongMA && currentShortMA>currentLongMA){
      if(Close[i+1]>High[i+2]){
         int artificiallyCounter=i+2;
         lowCheck=Low[artificiallyCounter];        
         bool loopCheck=True;
         while(loopCheck){
            if(lowCheck>Low[i+1]){
               lowCheck=Low[artificiallyCounter+1];
            }else{
               loopCheck=False;
               upStop_1[i+1]=lowCheck;
            }
         }
      }    
   }//if end
}

My Question:

1.Do i have mistakes on the Algorithm of the Trailingstop?

2.Why Is my code alway freezing?

Freezes because of array exceeded.

1. You should stop using the old event handlers and IndicatorCounted() and start using new event handlers.

2. double previousLongMA=iMA(NULL,0,13,0,MODE_EMA,PRICE_CLOSE,i+2);
   
         if(Close[i+1]>High[i+2]){

   Your lookback is two.

//---
   int lookback=5;
   int counted = IndicatorCounted();
   
//+------------------------------------------------------------------+
   for(int iBar=Bars-1-MathMax(lookback,counted);iBar>=0;--iBar){
      Print("Hello");
   }
//--- return value of prev_calculated for next call
   return(rates_total);
  }
//+------------------------------------------------------------------+

I did it like in the examples and tried a Hello but its freezing still

also freezing, I'm going crazy really...
