Chiến lược này sử dụng chỉ số ADX để xác định xu hướng thị trường, kết hợp với chỉ số DMI để xác định hướng, sử dụng độ dốc ADX để đo sức mạnh xu hướng, đặt mức khóa ADX để lọc các thị trường không có xu hướng và sử dụng đường trung bình động để lọc tín hiệu giao dịch.
Chiến lược này sử dụng đầy đủ sức mạnh của ADX trong việc xác định xu hướng và động lực, kết hợp với DMI để phân tích hướng, tạo thành một hệ thống theo dõi xu hướng hoàn chỉnh. Bộ lọc MA làm giảm tiếng ồn hiệu quả.
