Strategi ini menggunakan mekanisme pengujian balik dinamik pelbagai jangka masa untuk menentukan trend harga dengan membandingkan harga tertinggi dan terendah dalam tempoh masa yang berbeza, dengan itu mencapai arbitraj berisiko rendah.
Strategi ini mendapatkan harga tertinggi (nhigh) dan harga terendah (nlow) di pelbagai kerangka masa dengan memanggil fungsi tersuai f_get_htfHighLow. Khususnya, berdasarkan input yang ditakrifkan pengguna seperti resolusi tempoh masa, pengganda tempoh masa HTFMultiplier, parameter pengujian belakang, dan offset, ia memanggil fungsi keselamatan untuk mendapatkan harga tertinggi dan terendah dalam pelbagai kerangka masa.
Sebagai contoh, penyesuaian 0 mendapatkan harga tertinggi dan terendah bar semasa, sementara penyesuaian 1 mendapatkan harga tersebut dari bar sebelumnya. Dengan membandingkan perubahan harga antara bar, arah trend ditentukan.
Jika kedua-dua harga tertinggi dan terendah naik, trend bullish dikenal pasti. Jika kedua-dua harga jatuh, trend bearish dilihat. Posisi lama atau pendek diambil berdasarkan arah trend untuk melaksanakan perdagangan arbitraj.
Penyelesaian:
Logik strategi jelas, menggunakan pengujian balik dinamik pelbagai jangka masa untuk menentukan trend dan meminimumkan bias manusia. Dengan penyempurnaan melalui pengoptimuman parameter dan pengembangan ciri, ia menunjukkan potensi yang signifikan untuk meningkatkan kestabilan dan keuntungan yang layak untuk penyelidikan dan penjejakan lanjut.
