Karputov Vladimir:
Do you need an analogue of the right click on the chart and "Refresh" for the indicator?

Um... I don't need anything. All I said was that ChartRedraw() is not analogous to the "refresh" click.

choose the MetaQuotes-Demo server when you open a demo account

Yes, that's right. So that the indicator can calculate, but not address the init. ChartRedraw() does not do it.

Make the entire loop a function and call it with the required parameters from where you want.

For four

  static int FullOnCalculate( void )
  {
    long volume[];
    int spread[];

    ArraySetAsSeries(volume, TRUE);
    ArraySetAsSeries(spread, TRUE);

    const int Size = MathMin(CopyTickVolume(Symbol(), Period(), 0, Bars, volume),
                             CopySpread(Symbol(), Period(), 0, Bars, spread));

    return(OnCalculate(Size, 0, Time, Open, High, Low, Close, Volume, volume, spread));
  }

The same for the fifth.

Why does this class compile under MT4 but not under MT5?

class CHARTOBJECT
{
public:
  template <typename T>
#ifdef __MQL4__
  void SetProperty( const int id, const T Value, const int Modifier = 0 ) const
#else #endif
#ifdef __MQL5__
  void SetProperty( const ENUM_OBJECT_PROPERTY_STRING id, const T Value, const int Modifier = 0 ) const
#endif      
  {
    const string sType = typename(T);

    if (sType == "double")
      ::ObjectSetDouble(0, "", id, Modifier, (double)Value);
    else if (sType == "string")
      ::ObjectSetString(0, "", id, Modifier, (string)Value);
    else
      ::ObjectSetInteger(0, "", id, Modifier, (long)Value);

    return;
  } 
  
  virtual void operator =( const string Value ) const
  {
    this.SetProperty(OBJPROP_TEXT, Value);

    return;
  }
};

Is there an #else or #endif in there by any chance?

Комбинатор:
Is #else or #endif not unnecessary there?

In the#else #endif line, if I remove #endif, it doesn't compile. I don't know why it doesn't compile either.

But even if I remove all conditional compilation, it won't compile under MT5, but will compile under MT4.

Alexey Kozitsyn:
What is a multiterminal?)

It is a version of MT4 terminal, one instance of which allegedly can work with several accounts at the same time. I downloaded the installation file fcmt4multisetup_en.exe from FXCluba website. Is it their development in general and I am addressing to the wrong address?
