Idea utama strategi ini adalah untuk menggunakan persilangan purata bergerak cepat dan perlahan untuk menilai trend pasaran dan mengambil kedudukan apabila purata bergerak jangka pendek dan jangka panjang berbalik, untuk mencapai kesan trend pengesanan.
Strategi secara keseluruhan mempunyai logik yang jelas, mudah difahami, menggunakan pembalikan MA yang cepat dan perlahan untuk mengesan titik pembalikan trend. Secara teori ia dapat dengan berkesan mengesan trend. Tetapi dalam pelaksanaan sebenar ia masih memerlukan pengoptimuman algoritma itu sendiri dan penyesuaian parameter untuk menjadikannya lebih mantap dan praktikal.
