double High[];
double iHigh(string symbol,ENUM_TIMEFRAMES timeframe,int index)
  {
   double high=0;
   ArraySetAsSeries(High,true);
   int copied=CopyHigh(symbol,timeframe,0,Bars(symbol,timeframe),High);
   if(copied>0 && index<copied) high=High[index];
   return(high);
  }

 

This doesnt work

It crashes my MT5

 Why are the old iHigh functions removed anyway

Doesnt make sense at all

Step on New Rails: Custom Indicators in MQL5

I will not list all of the new possibilities and features of the new terminal and language. They are numerous, and some novelties are worth the discussion in a separate article. Also there is no code here, written with object-oriented programming, it is a too serous topic to be simply mentioned in a context as additional advantages for developers. In this article we will consider the indicators, their structure, drawing, types and their programming details, as compared to MQL4. I hope that this article will be useful both for beginners and experienced developers, maybe some of them will find something new.

You can try this, good luck.

double iHigh(string symbol,ENUM_TIMEFRAMES timeframe,int index)
  {
   if(index>-1)
     {
      double high[];
      if(CopyHigh(symbol,timeframe,index,1,high)>0)
         return(high[0]);
     }
   return(-1);
  }
