Strategi hentian pengekoran ATR adaptif
ChaoZhang
Strategi ini dinamakan sebagai Strategi Stop Tracking ATR Adaptif. Strategi ini menggunakan penunjuk ATR untuk menetapkan titik stop dan menukar stop dari ketat ke longgar setelah masuk untuk mengesan trend dan mengawal risiko.
Logik strategi ini adalah seperti berikut:
Harga tertinggi dan harga terendah dalam jangka masa tertentu dikira sebagai isyarat masuk, dan isyarat masuk dihasilkan apabila harga menembusi julat tersebut.
Selepas kemasukan, penutupan ATR yang lebih ketat digunakan pada mulanya, dengan titik penutupan tetap 1.5 kali nilai ATR. Ini dapat mengehadkan kerugian selepas kemasukan.
Pada tahap memegang, stop loss akan ditukarkan kepada ATR yang lebih longgar sebanyak 4 kali ganda. Stop loss terus menjejaki pergerakan harga, tetapi mempunyai ruang yang lebih besar untuk membolehkan permintaan terus diperpanjang.
Titik hentian akhir sentiasa mengesan harga terendah (paling banyak) atau harga tertinggi (tidak ada), menyesuaikan dengan turun naik harga, untuk mencapai kesan hentian.
Harga jatuh di bawah titik hentian kerugian (peluang) atau naik di atas titik hentian kerugian (peluang kosong).
Kelebihan strategi ini adalah bahawa ia menggunakan mekanisme berhenti yang beradaptasi, yang memastikan kawalan risiko dan mengelakkan berhenti terlalu awal. Tetapi parameter dan kelipatan ATR perlu dioptimumkan, dan strategi berhenti digunakan untuk menilai trend.
Secara umum, stop loss yang dinamika adalah cara penting untuk meningkatkan peluang keuntungan strategi. Dengan menggunakan stop loss secara fleksibel, anda dapat mengekalkan keuntungan trend dan mengawal risiko.
