print the average values to the "x" candle and the "x-1"

[texcs81]

Hi Guys, this function should print the average values to the "x" candle and the "x-1" candle but it prints the same value please help me fix it I do not understand where I am going wrong?

   for(int i=0; i<limit; i++) 
     { 
      //---- ma_shift set to 0 because SetIndexShift called abowe 
      MediaBuffer[i]=iMA(Symbol(),Period(),mediaPeriod,mediaShift,MODE_EMA,PRICE_CLOSE,i);
      Media=MediaBuffer[i]; //Verde
     
      MediaCandelaPrec=iMA(Symbol(),Period(),mediaPeriod,mediaShift,MODE_EMA,PRICE_CLOSE,i-1);
      
      if(NuovaCandela()==true)
         trendMediemmobili();
      }
       Comment("\nMedia Candela Prec: "+ DoubleToString(MediaCandelaPrec,3)+"\nMedia Candela: " +DoubleToString(Media,3));
 
   return(0)

See How to do your lookbacks correctly. Start using the new OnCalculate If mediaShift is negative, indexes less than that will always be blank. Must use the new form (#2) or recalculate all bars per tick.
