MQL5参考经济日历函数CalendarCountries 

CalendarCountries

获得“日历”中可用的国家名称数组。

int  CalendarCountries(
   MqlCalendarCountry&  countries[]         // 用于接收“日历”国家描述列表的数组
   );

参数

countries[]

[out] MqlCalendarCountry类型数组,用于接收所有“日历”国家的描述。

返回值

所接收的描述数量。若要获得有关错误的信息,请调用GetLastError()函数。可能错误:

  • 4001 – ERR_INTERNAL_ERROR(一般运行时错误)。
  • 5401 – ERR_CALENDAR_TIMEOUT(超过请求时限)。
  • 5400 – ERR_CALENDAR_MORE_DATA(数组大小不足以接收所有国家的描述,只可以接收那些适合的国家)。

 

例如:

//+------------------------------------------------------------------+
//| 脚本程序起始函数                                                     |
//+------------------------------------------------------------------+
void OnStart()
  {
//--- 从经济日历中获得国家列表
   MqlCalendarCountry countries[];
   int count=CalendarCountries(countries);
//--- 在“日志”中显示数组
   if(count>0)
      ArrayPrint(countries);
   else
      PrintFormat("CalendarCountries() returned 0! Error %d",GetLastError());
