Ini adalah strategi gabungan yang didorong oleh dua faktor - pembalikan dan bandpass, yang mencapai lapisan pelbagai faktor dan menyesuaikan diri dengan keadaan pasaran yang berbeza.
Strategi ini terdiri daripada dua sub-strategi:
123 Strategi Pembalikan: Apabila harga penutupan turun selama dua hari berturut-turut, jika penutupan hari ini menembusi harga terendah dalam dua hari sebelumnya, dan garis cepat osilator Stochastic 9 hari melintasi di atas garis perlahan, pergi panjang. Apabila harga penutupan naik selama dua hari berturut-turut, jika penutupan hari ini turun di bawah harga tertinggi dalam dua hari sebelumnya, dan garis cepat melintasi di bawah garis perlahan, pergi pendek.
Penapis Bandpass: Mengira penunjuk bandpass dalam tempoh tertentu, pergi panjang apabila ia di atas ambang, dan pergi pendek apabila di bawah.
Isyarat gabungan adalah: mengambil kedudukan panjang jika kedua-dua strategi memberi isyarat panjang, mengambil kedudukan pendek jika kedua-dua memberi isyarat pendek, sebaliknya membersihkan semua kedudukan.
Strategi ini mengintegrasikan faktor pembalikan dan trend untuk mencapai perdagangan kuantitatif yang didorong oleh pelbagai faktor. Pengesahan faktor dua mengurangkan kebarangkalian perdagangan yang salah, menjadikan strategi berfungsi dengan baik di pelbagai pasaran. Penambahbaikan lanjut pada penyesuaian parameter dan stop loss akan meningkatkan kestabilan dan keuntungan strategi.
