Strategi ini membina rentang harga yang lancar menggunakan purata bergerak yang lancar dan mengintegrasikan pelbagai purata bergerak yang lancar untuk menapis trend dalam masa nyata.
Dengan membina rentang harga yang lancar untuk menangkap trend harga, dan mengintegrasikan penapis purata bergerak untuk mengesahkan arah trend, strategi ini termasuk dalam strategi trend berikut yang tipikal.
Penyelesaian:
Strategi ini termasuk dalam strategi trend berikut yang terus mengesan trend harga dengan membina jalur purata bergerak yang lancar dan mengelakkan isyarat yang tidak sah dengan penapis yang membantu. Kelebihannya terletak pada membina jalur harga yang lancar untuk menangkap perubahan yang lebih baik dalam trend harga. Ia juga mempunyai risiko ketinggalan tertentu. Dengan pengoptimuman parameter dan pengoptimuman penunjuk, prestasi strategi dapat terus ditingkatkan dan bernilai penyelidikan lanjut.
