Strategi Jaringan Ikan yang Ditingkatkan
Strategi ini meningkatkan strategi Fish Net klasik dengan menambahkan ambang sinyal beli/jual dan stop loss untuk membentuk sistem trend berikut yang lebih lengkap.
Strategi jaring ikan menilai tren pasar dengan menghitung gaya sentroid harga, yang mencerminkan hubungan antara harga dan volume.
Kunci dalam menghitung gaya sentroid terletak pada hubungan antara harga dan waktu. Secara sederhana, perubahan harga baru-baru ini memiliki bobot yang lebih besar dalam mempengaruhi penilaian tren keseluruhan, sementara harga yang lebih tua memiliki bobot yang lebih kecil. Jadi ketika menghitung, bobot yang merosot waktu dikalikan. Ini membuat transaksi yang terjadi di tingkat yang lebih tinggi lebih mempengaruhi penilaian keseluruhan.
Tapi Fish Net asli hanya menilai panjang / pendek berdasarkan arah kurva centroid, mudah terjebak dalam gerakan sisi. Versi yang ditingkatkan ini menambahkan batas sinyal beli / jual yang ditentukan, hanya menghasilkan sinyal ketika gaya centroid melebihi magnitudo tertentu, menyaring banyak kebisingan.
Selain itu, versi yang disempurnakan menerapkan mekanisme gabungan trailing stop loss dan fixed stop loss untuk exit. Setelah memasuki tren, trailing stop loss dapat terus menyesuaikan dengan tindakan harga, mencapai kontrol risiko yang dinamis.
Tentu saja, indikator kekuatan sentroid memiliki kemampuan terbatas di pasar yang kompleks, dan trailing stop juga dapat ditembus jika tidak diatur dengan benar, sehingga pedagang perlu tetap waspada dan mengoptimalkan parameter secara tepat waktu.
