Strategi perdagangan jangka pendek ini menghasilkan sinyal beli dan jual berdasarkan rentang fluktuasi harga. Ini menghitung rentang pergerakan harga selama periode dan menggunakannya sebagai filter untuk sinyal perdagangan. Sinyal dipicu ketika harga keluar dari rentang.
Indikator inti adalah rentang fluktuasi harga.
Menghitung kisaran tinggi-rendah selama periode N terakhir sebagai amplitudo harga
Meratakan amplitudo menggunakan rata-rata bergerak untuk memperoleh filter kisaran
Sinyal beli dihasilkan ketika harga naik di atas filter rentang
Sinyal jual dihasilkan ketika harga turun di bawah filter rentang
Dengan cara ini, penyebaran kisaran harga digunakan untuk menentukan arah tren dan menyaring kebisingan untuk sinyal yang lebih bersih.
Risiko dapat dikurangi dengan:
Strategi dapat ditingkatkan dengan:
Pengujian periode perhitungan rentang yang berbeda
Mengoptimalkan koefisien volatilitas filter rentang
Menambahkan indikator konfirmasi seperti MACD
Menggunakan gerakan atau penghentian belakang
Parameter penyesuaian khusus untuk setiap produk
Mengoptimalkan sistem ukuran posisi
Strategi ini menggunakan price breaking out of ranges untuk menghasilkan sinyal jangka pendek, secara efektif menangkap tren sementara. Tetapi risiko seperti whipsaws ada. Perbaikan dapat dilakukan melalui optimasi parameter, stop loss, menambahkan filter dll untuk mengendalikan risiko sambil mempertahankan efektivitas. fine-tuning parameter oleh karakteristik produk juga penting. Optimasi terus menerus mengarah pada ketahanan.
