Gambaran umum

Logika Strategi

Inti dari strategi ini adalah untuk menentukan apakah harga berada dalam tren naik atau turun berdasarkan indikator tren yang dipilih oleh pengguna. Strategi pertama menghitung lebih dari 20 rata-rata bergerak dan garis regresi. Indikator ini termasuk indikator teknis umum dalam pustaka standar bahasa skrip Pine, serta beberapa indikator khusus yang ditulis oleh komunitas coder Pine. Strategi kemudian menanyakan nilai saat indikator yang dipilih dan membandingkannya dengan nilai sebelumnya. Jika nilai saat ini lebih besar dari nilai sebelumnya, tren naik. Jika nilai saat ini lebih kecil dari nilai sebelumnya, tren turun. Akhirnya, strategi menentukan apakah harus memasuki posisi panjang berdasarkan arah tren.
