Strategi ini adalah sistem perdagangan cerdas yang didasarkan pada indikator Brin Belt dan ATR, yang digabungkan dengan mekanisme stop loss multi-level. Strategi ini melakukan masuk ke dalam perdagangan multi-headed dengan mengidentifikasi sinyal reversal di dekat Brin Belt downtrend dan mengelola risiko dengan menggunakan metode stop loss tracking yang dinamis. Sistem ini dirancang untuk mencapai target keuntungan 20% dan stop loss 12%, sementara digabungkan dengan indikator ATR untuk mencapai stop loss tracking yang dinamis, yang dapat memberikan ruang yang cukup untuk perkembangan tren sambil melindungi keuntungan.
Logika inti dari strategi ini mencakup bagian-bagian utama berikut:
Strategi ini membangun sistem perdagangan bertingkat melalui Brin Belt dan ATR, menggunakan metode manajemen dinamis dalam entry, stop loss, dan profit. Keunggulan strategi ini adalah sistem kontrol risiko yang lengkap dan kemampuan untuk beradaptasi dengan fluktuasi pasar. Dengan arah optimasi yang disarankan, strategi ini memiliki ruang untuk peningkatan yang besar.
