Strategi ini menggabungkan penggunaan indikator bol band dan indikator rata-rata gelombang sebenar (ATR) untuk membentuk strategi perdagangan terobosan yang mempunyai fungsi hentian kerugian mengikut. Isyarat perdagangan dikeluarkan apabila harga melintasi jalur bol band yang tidak sesuai dengan piawaian yang ditetapkan.
Langkah pertama, mengira garis tengah, garis atas dan garis bawah. Garis tengah adalah purata bergerak sederhana harga SMA, dan garis atas dan bawah adalah bilangan bulat perbezaan harga piawai. Apabila harga menembus ke atas dari garis bawah, buat lebih banyak; apabila ia menembus ke bawah dari garis atas, buat kosong.
Langkah kedua, mengira indikator ATR. Indikator ATR mencerminkan purata turun naik harga. Berdasarkan nilai ATR, menetapkan kedudukan berhenti panjang dan kedudukan berhenti pendek.
Langkah ketiga, gunakan penapis masa dan hanya berdagang dalam tempoh masa yang ditetapkan untuk mengelakkan perubahan besar dalam peristiwa berita utama.
Langkah keempat, mekanisme trailing stop. Sesuai dengan kedudukan ATR terkini, sesuaikan stop loss dalam masa nyata untuk mengunci lebih banyak keuntungan.
Indeks Bollinger Bands sendiri mencerminkan pusat harga, lebih berkesan daripada purata bergerak tunggal.
ATR Stop Loss membolehkan setiap kadar keuntungan dan kerugian dapat dikawal dan mengawal risiko dengan berkesan;
Trailing stop boleh disesuaikan secara automatik dengan turun naik pasaran untuk mengunci lebih banyak keuntungan;
Ia mempunyai banyak parameter strategi dan anda boleh menyesuaikan portfolio peribadi anda.
Ia boleh menyebabkan kerugian kecil yang berulang apabila berlaku penyesuaian kejutan pasaran besar.
“Saya tidak tahu apa yang akan berlaku selepas ini.
Berdagang pada waktu malam dan semasa berita penting adalah berisiko, dan perlu dijauhi.
Kaedah pencegahan:
Strategi ini menggabungkan penggunaan indikator Boldenone untuk menentukan arah trend pusat dan pecah, indikator ATR untuk mengira stop loss untuk menjamin keuntungan dan kerugian, dan stop loss untuk mengunci keuntungan. Kelebihan strategi adalah sangat disesuaikan, boleh dikawal risiko, sesuai untuk garis pendek Perdagangan Intraday. Pengoptimuman parameter dan pembelajaran mesin dapat meningkatkan lagi peluang kemenangan dan keuntungan strategi.
