Strategi perdagangan dua garis lurus menghasilkan isyarat perdagangan dengan mengira purata bergerak indeks dari pelbagai kitaran, membentuk garis cepat dan lambat, dan melihat bentuk garpu emas dan garpu mati mereka. Apabila garis cepat melintasi garis perlahan dari bawah, buat lebih banyak; apabila garis cepat melintasi garis perlahan dari atas ke bawah, buat kosong.
Indikator utama strategi perdagangan dua hala adalah mengira garis cepat dan perlahan. Garis cepat menunjukkan purata bergerak indeks untuk tempoh pendek, parameter lalai adalah garis 12 hari; garis perlahan menunjukkan purata bergerak indeks untuk tempoh panjang, parameter lalai adalah garis 26 hari.
EMA(t) = (C(t) - EMA(t-1)) * SF + EMA(t-1)
Di antaranya, C (t) adalah harga penutupan hari itu, dan SF adalah faktor penyelarasan faktor penyelarasan. Perbezaan antara purata bergerak indeks dengan purata bergerak matematik biasa adalah bahawa purata bergerak indeks memberikan berat yang lebih besar kepada data terkini dan dapat bertindak balas lebih cepat terhadap perubahan harga.
Peraturan dagangan untuk strategi dua garis lurus ialah:
Meneroka bentuk persilangan garisan rata dengan menangkap dan bertindak balas tepat pada masanya terhadap perubahan hubungan dan trend permintaan pasaran, untuk mencapai keuntungan.
Strategi perdagangan dua hala sebagai strategi penunjuk teknikal yang lebih matang mempunyai kelebihan berikut:
Strategi perdagangan dua hala juga mempunyai kelemahan dan risiko:
Menghadapi risiko di atas, ia boleh dioptimumkan dengan cara seperti menyesuaikan parameter kitaran rata-rata, memperkenalkan penapis tambahan, dan lain-lain untuk memastikan strategi lebih mantap.
Strategi perdagangan dua hala boleh dioptimumkan dalam beberapa aspek:
Strategi perdagangan dua hala adalah strategi pilihan pertama untuk memasuki kuantitatif. Tetapi ada kekurangan tertentu, seperti menghasilkan isyarat palsu, yang memerlukan lebih banyak indikator untuk dioptimumkan, supaya lebih sesuai dengan jenis tertentu dan persekitaran perdagangan. Secara keseluruhan, strategi perdagangan dua hala adalah strategi penunjuk teknikal yang sangat praktikal.
