Tổng quan

Chiến lược này giao dịch giá bằng cách tích hợp nhiều chỉ số kỹ thuật. Kết hợp với việc sử dụng đường Super Signals, chỉ số MACD và chỉ số Laguerre RSI, chỉ tham gia khi nhiều chỉ số phát ra tín hiệu cùng một lúc, đồng thời thiết lập điểm dừng lỗ và dừng để kiểm soát tỷ lệ lợi nhuận rủi ro.
Nguyên tắc chiến lược

Đường Super Signals bao gồm các đường cơ sở, các kênh lên xuống và các vùng giao dịch. Chỉ số MACD đánh giá xu hướng dư thừa. Laguerre RSI đánh giá quá mua quá bán. Chỉ khi giá vượt qua kênh Super Signals, MACD đưa ra tín hiệu tương ứng và RSI cũng xác nhận, tín hiệu giao dịch sẽ được tạo ra.
Phân tích lợi thế

Xác nhận đa chỉ số để đảm bảo tín hiệu đáng tin cậy
Đường siêu tín hiệu đánh giá điểm hỗ trợ / kháng cự quan trọng
MACD đánh giá xu hướng chính
RSI lọc giả phá vỡ, tránh bị mắc kẹt
Khả năng kiểm soát rủi ro giao dịch
Phân tích rủi ro

Các thiết lập tham số chỉ số cần kiểm tra lặp lại để tối ưu hóa
Nhiều điều kiện hạn chế tần suất giao dịch
Không thể tối ưu hóa thời gian nắm giữ
Không thể xác định chính xác điểm đảo ngược xu hướng
Bạn có thể giảm rủi ro bằng cách điều chỉnh các tham số, thời gian nắm giữ và điều kiện dừng lỗ.
Hướng tối ưu hóa

Kiểm tra các kết hợp các tham số khác nhau, cân bằng tần suất và hiệu quả giao dịch
Cân nhắc các phương pháp khác để dừng lỗ, chẳng hạn như dừng lỗ di động
Kiểm tra các chỉ số khác nhau để đánh giá xu hướng đảo ngược
Kiểm tra sức mạnh của chiến lược trên nhiều thị trường và nhiều giống
Tóm tắt

Chiến lược này sử dụng tín hiệu xác nhận đa chỉ số, phản hồi hoạt động tốt. Bằng cách điều chỉnh các tham số hơn nữa, kiểm soát chặt chẽ rủi ro, có thể trở thành một hệ thống giao dịch định lượng ổn định và đáng tin cậy.
