전문가 고문 예: 헤지 계정에서 정지 없이 한 번에 두 개의 반대 위치를 엽니다.

EA 설정에는 두 가지 옵션이 있습니다.

  • TrailingStop(핍)
  • TrailingStep(핍)
TrailingStep은 지나치게 빈번한 수정에 대한 보호 기능입니다.

감사합니다, 처음은 아니었지만 작동했습니다!!!
 
흥미롭게도 세 개의 최대값(최소값)이 있는 경우 그 중 인덱스가 ArrayMaximum( ArrayMinimum )을 제공합니까?
 
Vladimir :
흥미롭게도 세 개의 최대값(최소값)이 있는 경우 그 중 어느 인덱스가 ArrayMaximum(ArrayMinimum)을 줄까요?
최대(최소). 이 함수에는 여러 출력 값이 없습니다.
 
Vitalie Postolache :
최대(최소). 이 함수에는 여러 출력 값이 없습니다.
그것이 내가 묻는 것입니다. 배열에는 5개의 숫자가 있습니다. 1.1012 1.1013 1.1013 1.1013 1.1012, 함수가 최대값을 고려하는 요소는 무엇입니까? 대부분 - 아니요, 똑같이 큰 세 가지가 있습니다. 답변 옵션: 첫 번째 충족, 마지막 충족, 최대값 중 하나. 원하는 경우 더 많은 옵션을 제공할 수 있습니다. 선택은 도움말(문서)의 기능 설명에 반영되어야 하는데 찾지 못했습니다.
