Strategi ini dinamakan
Logiknya ialah:
Mengira julat harga tertinggi dan terendah dalam tempoh tertentu sebagai isyarat kemasukan.
Selepas masuk, hentian ATR yang lebih ketat digunakan pada mulanya, ditetapkan pada 1.5 kali nilai ATR, untuk mengehadkan kehilangan selepas masuk.
Semasa memegang perdagangan, hentian ditukar kepada yang lebih longgar 4 kali ATR. Hentian mengekalkan harga tetapi membolehkan lebih banyak ruang untuk trend untuk meluas.
Tahap hentian sentiasa mengesan harga terendah (dagang panjang) atau harga tertinggi (dagang pendek) dan menyesuaikan dengan turun naik harga, mencapai kesan hentian.
Apabila harga jatuh di bawah paras berhenti (panjang) atau meningkat di atasnya (pendek), kerugian berhenti dicetuskan.
Kelebihan strategi ini adalah menggunakan mekanisme stop loss adaptif untuk memastikan kawalan risiko sambil mengelakkan hentian awal.
Kesimpulannya, hentian yang dinamis adalah cara penting untuk meningkatkan keuntungan. Aplikasi hentian kerugian yang fleksibel dapat lebih baik mengekalkan keuntungan trend dan mengawal risiko.
