Strategi Dagangan Rata-Rata Bergerak Penembusan Harga Arahan Dua adalah strategi perdagangan kuantitatif yang menggunakan penembusan harga purata bergerak untuk menentukan isyarat perdagangan. Ia membandingkan harga dengan purata bergerak tempoh tertentu dan menghasilkan isyarat perdagangan apabila harga memecahkan purata bergerak.
Logik teras strategi ini ialah:
Mengira purata bergerak (EMA) bagi tempoh tertentu (contohnya 200 hari) menggunakan fungsi EMA.
Bandingkan harga penutupan dengan EMA untuk menentukan sama ada harga memecahkan EMA. Khususnya, apabila harga penutupan di atas EMA, harga pecah melalui EMA; apabila harga penutupan di bawah EMA, harga pecah melalui EMA.
Tentukan isyarat panjang dan pendek berdasarkan terobosan. Apabila harga pecah melalui EMA, menjana isyarat panjang; apabila harga pecah melalui EMA, menjana isyarat pendek.
Apabila isyarat dicetuskan, letakkan pesanan dengan peratusan tertentu (contohnya 100%) dan tetapkan harga stop loss dan mengambil keuntungan.
Apabila harga stop loss atau mengambil keuntungan disentuh, kedudukan ditutup.
Ulangi proses ini untuk mendapat keuntungan daripada masa harga memecahkan purata bergerak.
Strategi ini adalah mudah dan mudah difahami dan dilaksanakan. Ia bertujuan untuk menangkap momentum jangka pendek dengan isyarat memecahkan purata bergerak. Tetapi ia juga mempunyai risiko ketinggalan dan whipsaw tertentu.
Kaedah pengoptimuman termasuk penyesuaian parameter, menggunakan penunjuk yang lebih berkesan, mengurangkan kekerapan perdagangan dan lain-lain. Hentian penyesuaian dan keadaan penapisan juga dapat mengawal risiko.
Strategi ini mempunyai logik yang agak mudah untuk mengesan purata bergerak untuk menangkap momentum jangka pendek. Kelebihan termasuk tindak balas dan kemudahan penggunaan; kelemahan termasuk kelewatan dan kelemahannya. Pengoptimuman lanjut boleh dilakukan pada pemilihan penunjuk, mekanisme hentian kerugian, teknik penapisan untuk menjadikan strategi lebih kukuh dan komprehensif.
