Get Symbol Open / Closed Price

 

Hi, I just started to mql5. 

How can I see a symbol of the opening and closing price? 

 

      alis =  SymbolInfoDouble(_sembol,SYMBOL_ASK);

      satis =  SymbolInfoDouble(_sembol,SYMBOL_BID);

      son =  SymbolInfoDouble(_sembol,SYMBOL_LAST);

      yuksek = SymbolInfoDouble(_sembol,SYMBOL_LASTHIGH);

      dusuk = SymbolInfoDouble(_sembol,SYMBOL_LASTLOW);

      kapanis = SymbolInfoDouble(_sembol,SYMBOL_SESSION_CLOSE);

      acilis = SymbolInfoDouble(_sembol,SYMBOL_SESSION_OPEN);

Which opening and closing price ?
 
does not matter. for example; eurusd, gbpusd

This is not my question. What is "the opening and closing price" ? Opening and closing of what ?
