Strategi ini berdasarkan pada EMA untuk melakukan pengesanan dua hala dan menetapkan garis berhenti dan kehilangan yang dinamik untuk menangkap trend.
Ia boleh dioptimumkan dengan menggunakan ATR untuk mengawal risiko, mengoptimumkan strategi berhenti jangka pendek, atau menggabungkannya dengan perdagangan penapis bunyi indikator lain.
Strategi ini secara keseluruhannya adalah strategi pengesanan trend yang sangat tipikal. Dua EMA membentuk garpu mati, stop loss dinamik, yang dapat mengunci keuntungan trend dengan berkesan. Di samping itu, terdapat risiko ketinggalan dan risiko stop loss yang terlalu luas.
