Strategi ini adalah sistem perdagangan pengesanan trend berdasarkan penembusan Saluran Donchian, yang menggabungkan indikator SuperTrend dan penapis kuantiti transaksi untuk meningkatkan kebolehpercayaan isyarat perdagangan. Strategi ini mengidentifikasi peluang perdagangan berbilang arah yang berpotensi dengan menangkap harga yang melampaui ketinggian sejarah, sambil menggunakan pengesahan kuantiti transaksi dan indikator pengesanan trend untuk menyaring isyarat penembusan palsu.
Logik teras strategi adalah berdasarkan komponen utama berikut:
Strategi ini membina sistem perdagangan trend yang agak lengkap dengan menggunakan pelbagai petunjuk teknikal secara komposit. Kelebihan strategi ini adalah kebolehpercayaan isyarat yang tinggi, fleksibiliti pengurusan risiko, tetapi masih memerlukan pedagang untuk mengoptimumkan parameter mengikut ciri-ciri pasaran tertentu. Dengan penambahbaikan dan pengoptimuman berterusan, strategi ini dijangka mendapat kesan perdagangan yang stabil di pasaran trend.
