이 전략은 여러 통계 대역과 트렌드 분석을 기반으로 한 거래 전략이다. 이 전략은 브린 대역, 분기 대역, 그리고 律을 사용하여 중요한 지지/저항 지역을 식별하고, 상위 분기 대역의 하위 표준 차이를 트리거 신호로 사용하여 입출시와 출출시를 결정한다. 전략 설계는 시장의 변동성을 충분히 고려하여 여러 통계 방법을 중첩하여 신호의 신뢰성을 높인다.
전략의 핵심 원칙은 여러 통계 대역의 교차로 시장 추세를 포착하는 것입니다. 주로 다음과 같은 몇 가지 핵심 구성 요소를 포함합니다.
이것은 여러 가지 통계적 방법을 결합한 통합적 트렌드 추적 전략이다. 브린 밴드, 분수 밴드 및 律 밴드의 연동 작용을 통해 시장 추세를 더 잘 파악할 수 있으며, 동시에 좋은 위험 제어 능력을 갖추고 있다. 약간의 낙후성과 매개 변수 최적화 어려움이 있음에도 불구하고, 지속적인 개선과 최적화를 통해 이 전략은 더 나은 실용적 가치와 발전 전망을 가지고 있다.
