이 전략의 주요 아이디어는 칼만 필터와 추적 스톱을 결합하여 동적으로 조정된 스톱 궤도를 구축하는 것입니다. 칼만 필터는 가격을 추적하고 가격의 예측 값을 제공합니다. 스톱 궤도는 예측에 따라 일정 비율로 구성되어 동적으로 추적 된 가격을 구현합니다. 이렇게 우세한 운영 단계에서 이탈리아를 바꾸고 역동적인 시기에 손실을 중단 할 수 있습니다.
전체적인 전략은 트렌드 시장에서 좋은 효과를 얻을 수 있습니다.
이 전략은 다음과 같은 부분들로 구성됩니다.
칼만 필터
정지 궤도
상장 및 정지
전체 전략의 주요 운영 과정은 다음과 같습니다.
이 전략의 주요 장점은 다음과 같습니다.
이 전략의 주요 위험은 다음과 같습니다.
다음의 방법으로 최적화할 수 있습니다.
이 전략은 다음과 같은 측면에서 최적화될 수 있습니다.
전체적으로, 이 적응형 상쇄 궤도 전략은 칼만 예측과 동적 상쇄를 결합하여 비교적 독특한 사고 방식을 형성한다. 적절한 변수 조정을 할 경우, 좋은 효과를 얻을 수 있다. 추가 모듈화 설계 및 최적화를 통해, 이 전략을 더욱 완성하여 더 많은 시장에서 적용할 수 있다.
