Chiến lược này xác định các tín hiệu mua và bán bằng cách xác định nhiều mô hình hình dạng giá trong biểu đồ K. Chiến lược này kết hợp các phương pháp phân tích kỹ thuật như ý kiến dư luận, lý thuyết Dow, và sử dụng hơn một chục mô hình đồ họa phổ biến để nắm bắt các điểm biến của thị trường.
Cốt lõi của chiến lược này là nhận diện các hình dạng K khác nhau, bao gồm các hình dạng bao bì, Harami, xuyên, và Morning Star. Khi nhận diện hình dạng dương, tạo ra tín hiệu mua; khi nhận diện hình dạng âm, tạo ra tín hiệu bán.
Ví dụ, khi nhận ra ba hình thức lính trắng, cho thấy ba dòng K đầu tiên là đường dài, và mỗi giá đóng cửa của K vượt quá giá mở cửa, đại diện cho việc mua mạnh thúc đẩy giá cổ phiếu cao hơn, do đó tạo ra tín hiệu mua.
Mỗi hình dạng có một thuật toán cụ thể để nhận biết. Chiến lược sẽ đi qua lịch sử K-line để xác định xem mỗi thanh có thỏa mãn một số thuật toán xây dựng hình dạng nào đó hay không, và khi thỏa mãn, nó sẽ được đánh dấu trên biểu đồ vẽ bar tương ứng.
Chiến lược này thông qua phân tích kỹ thuật đồ họa, xác định nhiều hình thái quan trọng trên đường K, để đánh giá xu hướng tương lai của thị trường. Chiến lược có tính thực tế mạnh mẽ, nhưng thương nhân cũng cần chú ý đến môi trường cổ phiếu lớn để tránh mất xu hướng lớn do hình thái địa phương. Bằng cách tối ưu hóa hơn nữa, có khả năng nâng cao tính ổn định và lợi nhuận của chiến lược.
