Strategi ini menggabungkan dua rata-rata bergerak eksponensial dan tiga rata-rata bergerak Williams untuk membentuk sistem sinyal pelacakan tren dan pembalikan tren yang komprehensif.
Selain itu, strategi ini memiliki ruang pengoptimalan parameter yang besar. Dengan menyesuaikan parameter rata-rata bergerak ganda dan tiga rata-rata bergerak Williams, ia dapat beradaptasi dengan karakteristik varietas dan siklus yang berbeda, dan memiliki kemampuan beradaptasi yang kuat.
Risiko utama dari strategi ini adalah bahwa ketika pasar memasuki fluktuasi yang ganas, titik stop loss dapat rusak, menghasilkan kerugian yang lebih besar. Ini adalah masalah umum dengan strategi moving average. Selain itu, di pasar osilasi, strategi ini dapat sering membuka dan menutup posisi, meningkatkan biaya biaya perdagangan.
