Strategi Trading Reversal Volatility Breakout adalah strategi trading reversal yang melacak saluran harga dengan titik stop profit dan stop loss bergerak adaptif.
Strategi ini pertama-tama menggunakan indikator Wilder's Average True Range (ATR) untuk mengukur volatilitas harga. Kemudian menghitung Average Range Constant (ARC) berdasarkan nilai ATR. ARC mewakili setengah lebar saluran harga. Selanjutnya, band atas dan bawah saluran dihitung sebagai titik stop profit dan stop loss, juga dikenal sebagai titik SAR. Ketika harga melanggar band atas, posisi pendek dibuka. Ketika harga melanggar band bawah, posisi panjang dibuka.
Secara khusus, ATR di atas N bar terakhir dihitung terlebih dahulu. ATR kemudian dikalikan dengan faktor untuk mendapatkan ARC, yang mengontrol lebar saluran harga. Menambahkan ARC ke harga penutupan tertinggi di atas N bar memberikan band atas saluran, atau SAR tinggi. Mengurangkan ARC dari harga penutupan terendah memberikan band bawah, atau SAR rendah. Jika harga ditutup di atas band atas, posisi pendek diambil. Jika harga ditutup di bawah band bawah, posisi panjang diambil.
Solusi:
Strategi Trading Reversal Volatility Breakout menggunakan saluran untuk melacak perubahan harga dan membalikkan posisi ketika volatilitas memuncak. Ini bekerja dengan baik di pasar yang terikat rentang dengan pembalikan, menghasilkan pengembalian yang baik jika titik pembalikan diidentifikasi dengan akurat.
