How to calculate EMA from Volume in MQL5. In MQL4 it had iMAonArray() function, but in MQL5 I think it's absent.

I have to create a handle foriVolumes indicator. Then create an iMA indicator handle, but use iVolumes handle instead of price:

//--- create handle of the indicator
   handle_iVolumes=iVolumes(Symbol(),Period(),Inp_Volumes_applied_volume);
//--- if the handle is not created
   if(handle_iVolumes==INVALID_HANDLE)
     {
      //--- tell about the failure and output the error code
      PrintFormat("Failed to create handle of the iVolumes indicator for the symbol %s/%s, error code %d",
                  Symbol(),
                  EnumToString(Period()),
                  GetLastError());
      //--- the indicator is stopped early
      return(INIT_FAILED);
     }
//--- create handle of the indicator iMA
   handle_iMA=iMA(Symbol(),Period(),Inp_MA_ma_period,Inp_MA_ma_shift,
                  Inp_MA_ma_method,handle_iVolumes);
//--- if the handle is not created
   if(handle_iMA==INVALID_HANDLE)
     {
      //--- tell about the failure and output the error code
      PrintFormat("Failed to create handle of the iMA indicator for the symbol %s/%s, error code %d",
                  Symbol(),
                  EnumToString(Period()),
                  GetLastError());
      //--- the indicator is stopped early
      return(INIT_FAILED);
     }

Why? What's it got to do with it? And if so, what other options are there?

What is the problem with the data? Visually it seems to be the same as Volume+MA indicator, I've scrolled through the history

The only difference is long and double data type

Take a look at this. It may not be a general glitch, but it's also tense in a particular case...
