@Mladen Rakic Hi bro, what are those means?

? and :

         val[i]  = (i>0) ? 0.5*MathLog((1.0+work[i])/(1.0-work[i]))+0.5*val[i-1] : 0;      
         valc[i] = (i>0) ? (val[i]>val[i-1]) ? 1 : (val[i]<val[i-1]) ? 2 : 0 : 0;

and I am curious about the iCustom(... , ...)

I mean

I have an EA at MT4 and I control the condition like that "bool Long()"

How to convert your indicator for iCustom from MQL4 to MQL5?

My EA's some part for Fisher condition:

bool Long()
   {  
      bool   flag=false;
      double Fisher[4], Trigger[4];
      ArrayInitialize(Fisher,EMPTY_VALUE);
      ArrayInitialize(Trigger,EMPTY_VALUE);
      int    i, limit=ArraySize(Fisher);     
       
      for(i=0; i<limit; i++)
         {  
            Fisher[i]=iCustom(NULL,0,"FTI",Periyot,0,i);
            Trigger[i]=iCustom(NULL,0,"FTI",Periyot,1,i);           
         }
     
      if (  Fisher[1]  <= (Level*(-1)) &&  
            Trigger[1] <= (Level*(-1)) &&
            Fisher[1]  >  Trigger[1]   &&
            Fisher[2]  <  Trigger[2]    )
            {
             flag=true;
            } 
      return(flag);
   }

I think, like that, right?

            val[i]=iCustom(NULL,0,"FTI",inpPeriod,0,i);
            valc[i]=iCustom(NULL,0,"FTI",inpPeriod,1,i);
