Strategi titik persilangan terbuka adalah strategi perdagangan kuantitatif berdasarkan persilangan purata bergerak. Ia menentukan trend harga dengan mengira persilangan antara garis purata bergerak pantas dan perlahan dan menghasilkan isyarat beli dan jual di titik persilangan. Strategi ini menggunakan Purata Bergerak Hull sebagai garis pantas dan penapis Super Smoother sebagai garis perlahan. Gabungan ini menggabungkan kedua-dua kelancaran dan keupayaan penentuan trend purata bergerak dan dapat mengenal pasti pergerakan harga dengan berkesan untuk menghasilkan isyarat perdagangan yang agak boleh dipercayai.
Rumus untuk mengira strategi titik persilangan terbuka adalah: Laluan pantas (Hull MA): WMA(2 * WMA(harga, n/2) - WMA(harga, n), SQRT(n)) Garis perlahan (Super Smoother Filter): Penapis tiga harga
Di mana WMA adalah Purata Bergerak Bertimbang, SQRT adalah akar kuadrat, dan penapis mengandungi satu istilah lag urutan pertama dan dua istilah lag urutan kedua.
Strategi ini menilai hubungan antara garis cepat dan perlahan dengan mengira nilai mereka.
Pembebasan ke atas talian pantas adalah isyarat beli
Perpindahan ke bawah talian pantas adalah isyarat jual
Strategi titik silang dekat terbuka menggabungkan kelebihan penilaian purata bergerak berganda dan perdagangan titik. Ia dapat menangkap dengan tepat titik perubahan trend untuk kemasukan dan keluar tepat pada masanya. Berbanding dengan strategi purata bergerak tunggal, ia mempunyai kelebihan berikut:
Strategi mata silang terbuka juga membawa risiko tertentu:
Strategi titik silang dekat terbuka boleh dioptimumkan dalam dimensi berikut:
Strategi titik silang dekat terbuka mewarisi kelebihan strategi purata bergerak sambil memperluaskan penggunaan penilaian purata bergerak berganda dan model perdagangan titik untuk membentuk skema perdagangan kuantitatif yang lebih maju dan boleh dipercayai. Ia mempunyai kelebihan unik dalam perdagangan masa yang layak diuji secara langsung dan penerokaan aplikasi.
