Chiến lược này phát triển một chiến lược giao dịch định lượng tương đối ổn định và đáng tin cậy bằng cách kết hợp sử dụng chỉ số trung bình di chuyển ba và chỉ số MACD. Nó nhằm mục đích nắm bắt các xu hướng trong tương lai có thể và đặc biệt phù hợp với cổ phần trung và dài hạn.
Chiến lược chủ yếu dựa trên sự kết hợp của trung bình di chuyển ba và chỉ số MACD.
Đầu tiên, chiến lược sử dụng trung bình động nhân ba với chiều dài lần lượt là 3, 7 và 2. Ba trung bình động này xây dựng một hệ thống trung bình động nhanh đến chậm để xác định hướng của xu hướng trong tương lai. Khi trung bình động ngắn hạn vượt qua trung bình động dài hạn, đó là một tín hiệu dài; khi trung bình động ngắn hạn vượt dưới trung bình động dài hạn, đó là một tín hiệu ngắn.
Thứ hai, chiến lược cũng sử dụng chỉ số MACD với các tham số 3 và 7 đồng thời. Khi đường chính MACD vượt qua đường tín hiệu, đó là tín hiệu dài, và khi nó vượt qua bên dưới, đó là tín hiệu ngắn.
Bằng cách kết hợp việc sử dụng hai chỉ số, nó có thể tránh nhiều tín hiệu sai do một chỉ số duy nhất gây ra, do đó cải thiện sự ổn định của chiến lược.
Giải pháp:
Chiến lược này đạt được xu hướng ổn định thông qua sự kết hợp giữa đường trung bình động và MACD. Ưu điểm của nó nằm trong việc sử dụng kết hợp các chỉ số, có thể giảm hiệu quả tín hiệu sai và đạt được hiệu suất chiến lược tốt hơn.
