Strategi titik persilangan dua garis rata adalah strategi perdagangan kuantitatif berdasarkan purata bergerak. Ia menentukan trend harga dengan mengira persilangan garis cepat dan lambat, dan menghantar isyarat beli dan jual di persilangan. Strategi ini menggunakan garis rata Hull sebagai garis cepat dan penapis Super Smoother sebagai garis perlahan.
Rumus pengiraan untuk strategi titik titik dua garis sejajar adalah seperti berikut:
Garis laju ((Hull mean line): WMA ((2 * WMA ((value,n/2) -WMA ((value,n),SQRT ((n))
Garis perlahan ((Super Smoother): Nilai tiga kali penapis
Di antaranya, WMA mewakili purata bergerak bertimbangan, SQRT mewakili akar kuadrat terbuka, dan penapis mengandungi satu ketinggalan satu peringkat dan dua ketinggalan peringkat kedua.
Strategi untuk menentukan hubungan silang antara dua garis dengan mengira nilai garis cepat dan lambat, di mana:
Menerobos talian perlahan untuk membeli isyarat
Garis laju di bawah garis perlahan adalah isyarat untuk menjual.
Strategi titik titik silang dua garis rata menggabungkan kelebihan penilaian dua garis rata dan perdagangan titik, dapat menangkap titik perubahan trend dengan tepat, masuk dan keluar tepat pada masanya. Berbanding dengan strategi garis rata tunggal, ia mempunyai kelebihan berikut:
Strategi dua titik persilangan linear juga mempunyai risiko:
Strategi titik titik penyambungan dua garis sejajar boleh dioptimumkan dari dimensi berikut:
Strategi titik titik silang dua garis rata mewarisi kelebihan strategi garis rata, mengembangkan penggunaan penilaian dua garis rata dan cara perdagangan titik, membentuk satu program perdagangan kuantitatif yang lebih maju dan dipercayai. Ia mempunyai kelebihan yang unik dalam perdagangan masa, yang patut diuji dan diterokai.
