Strategi ini menggunakan kombinasi antara Brin Band dan Triple Overtrend Indicator untuk melakukan perdagangan. Dengan penilaian jangkauan fluktuasi Brin Band dan pengesahan tren Triple Overtrend, membentuk sistem pelacakan tren yang kuat. Brin Band digunakan untuk mengidentifikasi fluktuasi ekstrim harga, sedangkan Triple Overtrend memberikan pengesahan arah tren secara ganda melalui pengaturan parameter yang berbeda.
Logika inti dari strategi ini mencakup bagian-bagian utama berikut:
Ini adalah strategi pelacakan tren yang menggabungkan pita Brin dan triple overtrend untuk meningkatkan keandalan perdagangan dengan konfirmasi beberapa indikator teknis. Strategi ini memiliki kemampuan menangkap tren yang kuat dan kemampuan mengendalikan risiko, tetapi juga perlu memperhatikan dampak lingkungan pasar pada kinerja strategi. Dengan terus-menerus mengoptimalkan dan menyempurnakan, strategi diharapkan dapat mempertahankan kinerja yang stabil di berbagai kondisi pasar.
