[MQL5] Open several charts

[ket314MQL4]

Hello,

I would like to know how to open several charts in mql5 ?
I tried to do this but there is only one graph that opens

(I run the code I execute the program by doing ctrl + f5)

//+------------------------------------------------------------------+
//| Expert initialization function                                   |
//+------------------------------------------------------------------+
int OnInit()
  {
//---
   ChartOpen("EURUSD", PERIOD_H1);
   ChartOpen("EURCHF", PERIOD_H1);
//---
   return(INIT_SUCCEEDED);
  }
//+------------------------------------------------------------------+
//| Expert deinitialization function                                 |
//+------------------------------------------------------------------+
void OnDeinit(const int reason)
  {
//---
   
  }
//+------------------------------------------------------------------+
//| Expert tick function                                             |
//+------------------------------------------------------------------+
void OnTick()
  {

  }

If there is no symbol in the "Market Watch" window, OpenChart will not work. To protect yourself, use SymbolSelect
