Strategi ini adalah sistem dagangan berdasarkan tindakan harga dan tahap sokongan / rintangan dinamik, melaksanakan dagangan berhampiran tahap harga utama apabila corak lilin tertentu muncul. Sistem ini menggunakan kaedah pengiraan sokongan / rintangan dinamik 16 tempoh, digabungkan dengan empat corak lilin pembalikan klasik - Hammer, Shooting Star, Doji, dan Pin Bar untuk menangkap pembalikan pasaran yang berpotensi.
Inti strategi ini terletak pada mengira secara dinamik tahap sokongan dan rintangan untuk menubuhkan sempadan pergerakan harga. Apabila harga mendekati tahap utama ini, sistem mencari corak lilin tertentu sebagai isyarat pembalikan. Syarat kemasukan memerlukan pembentukan corak dalam 1.8% (sensitiviti lalai) tahap sokongan / rintangan. Sistem melaksanakan peraturan pengurusan ekuiti 35% dengan 16% stop-loss dan 9.5% mengambil keuntungan, dengan berkesan mengawal risiko pada kira-kira 5.6% daripada jumlah ekuiti setiap perdagangan. Strategi ini dilaksanakan dalam Script Pine dengan fungsi pengurusan perdagangan lengkap dan visualisasi.
Strategi perdagangan berasaskan tindakan harga ini menyediakan peniaga dengan pendekatan perdagangan yang sistematik dengan menggabungkan tahap sokongan / rintangan dinamik dengan corak pembalikan klasik. Kekuatan strategi terletak pada logiknya yang jelas dan risiko yang boleh dikawal, walaupun pengoptimuman berterusan berdasarkan hasil perdagangan sebenar adalah perlu. Pedagang dinasihatkan untuk menjalankan pengujian balik dan pengoptimuman parameter yang menyeluruh sebelum perdagangan langsung, dan menyesuaikan strategi berdasarkan pengalaman pasaran.
