my expert returns wrong value of my indicator

New comment
 

hi guys , i wrote an indicator, and when i use it in expert in strategy tester, it just comment me true valumes for only 5-6 candles. then it comment a fixed wrong value like 2147483647.00

void OnTick()
  {
  if(NormalizeDouble(Volume[1],0)<=200 && NormalizeDouble(iCustom(Symbol(),PERIOD_M5,"taghir hajm",1,1),2)>=0.15)
   //{
   // Comment(Volume[1]+"hiiiiiii");
  Comment("fallll = "+DoubleToStr(NormalizeDouble(iCustom(Symbol(),PERIOD_M5,"taghir hajm",1,1),2),2));
  // }
  }
 
  1. 2147483647.00  is EMPTY_VALUE.

  2. Do you really expect an answer? There are no mind readers here and our crystal balls are cracked. We can't see your indicator.

this is the indicator

  
   for(i=0; i<limit; i++)
      {
          ExtNesbatBuffer[i]=fabs(iClose(Symbol(),0,i)-iOpen(Symbol(),0,i))*80000/(iVolume(Symbol(),0,i));

Your loop is indexing as non-series. Your buffers and function calls are indexed as-series.
