초보자의 질문 MQL5 MT5 MetaTrader 5

Sprut 185 2021.05.16 19:33 #13061

안녕하세요!

MQL4에서 MQL5로 표시기를 전송하고 있는데 작동하지 않는 이유를 이해할 수 없습니다.

 void GetDellName( string name_n = " " )
  {
   string vName;
   for ( int i= ObjectsTotal ()- 1 ; i>= 0 ; i--)
     {
      vName = ObjectName (i);
       if ( StringFind (vName,name_n) !=- 1 )
         ObjectDelete (vName);
     }
  }

MQL5의 MetaEditor는 다음과 같이 맹세합니다.

' ObjectsTotal ' - 잘못된 매개변수 개수

'ObjectName' - 잘못된 매개변수 개수

'ObjectDelete' - 잘못된 매개변수 개수

그러나 MQL4에서는 모든 것이 쾅하고 작동하며 오류가 없습니다.

이해를 도와주세요

이해를 도와주세요

1. 코드를 올바르게 붙여넣으십시오. 메시지를 편집할 때 버튼을 누르십시오. 그리고 나타나는 팝업 창에서 코드를 붙여넣습니다(처음으로 메시지를 편집했습니다).

2. 도움말을 주의 깊게 읽으십시오. 예를 들어 ObjectsTotal

 int    ObjectsTotal (
   long   chart_id,           // идентификатор графика
   int    sub_window=- 1 ,       // индекс окна
   int    type=- 1              // тип объекта     
   );

어쩌면 그렇게? - 모든 수평선과 추세선을 제거합니다.

주기가 있는 이유는 무엇입니까?

 int    ObjectsDeleteAll (
   long   chart_id,             // идентификатор графика
   int    sub_window=- 1 ,       // индекс окна
   int    type=- 1                // тип объекта для удаления

솔직히!? - 몰라! - 그래서, 아침에 바쁘지 않습니다.
