Strategi ini membangun amplop volatilitas dinamis berdasarkan metode regresi kernel Nadaraya-Watson untuk menghasilkan sinyal perdagangan membeli rendah dan menjual tinggi dengan melacak situasi silang antara harga dan band amplop.
Inti dari strategi ini adalah untuk menghitung amplop dinamis harga. Pertama, dengan menggunakan jendela lookback kustom, ia membangun kurva regresi kernel Nadaraya-Watson harga (dekat, tinggi, rendah) untuk mendapatkan perkiraan harga yang halus. Kemudian ia menghitung ATR berdasarkan panjang ATR kustom, dan membentuk band amplop atas dan bawah dengan faktor dekat dan jauh. Ketika harga masuk ke amplop dari bawah, sinyal beli dihasilkan. Ketika harga keluar dari amplop dari atas, sinyal jual dipicu. Dengan melacak hubungan dinamis antara harga dan sifat statistik terkait volatilitas, strategi menyesuaikan keputusan tradingnya secara adaptif.
Optimalisasi yang tepat, backtest yang cukup, pemahaman faktor kunci dan ukuran posisi yang bijaksana dalam perdagangan langsung dapat membantu mengurangi risiko ini.
Strategi ini menggabungkan analisis statistik dan analisis indikator teknis untuk menghasilkan sinyal perdagangan dengan melacak secara dinamis hubungan antara harga dan volatilitas. Parameter dapat disesuaikan berdasarkan kondisi pasar dan kebutuhan pribadi. Secara keseluruhan, meskipun memiliki dasar teoritis yang kuat, kinerja sebenarnya masih perlu diverifikasi lebih lanjut. Seseorang harus memperlakukannya dengan hati-hati dan berdagang dengan hati-hati.
