MQL4 Reference Custom Indicators IndicatorCounted

IndicatorCounted

The function returns the amount of bars not changed after the indicator had been launched last.

int IndicatorCounted();

Returned value

The amount of bars not changed after the indicator had been launched last.

Note

The most calculated bars do not need any recalculation. In most cases, same count of index values do not need for recalculation. The function is used to optimize calculating.

Example:

  int start()
    {
     int limit;
     int counted_bars=IndicatorCounted();
  //---- check for possible errors
     if(counted_bars<0) return(-1);
  //---- the last counted bar will be recounted
     if(counted_bars>0) counted_bars--;
     limit=Bars-counted_bars;
  //---- main loop
     for(int i=0; i<limit; i++)
       {
        //---- ma_shift set to 0 because SetIndexShift called abowe
        ExtBlueBuffer[i]=iMA(NULL,0,JawsPeriod,0,MODE_SMMA,PRICE_MEDIAN,i);
        ExtRedBuffer[i]=iMA(NULL,0,TeethPeriod,0,MODE_SMMA,PRICE_MEDIAN,i);
        ExtLimeBuffer[i]=iMA(NULL,0,LipsPeriod,0,MODE_SMMA,PRICE_MEDIAN,i);
       }
  //---- done
     return(0);
    }
