Strategi ini mengimplementasikan perdagangan pola harga dengan mengidentifikasi pola candlestick. Ini mencari pola pinbar terdekat dan pergi panjang atau pendek berdasarkan sinyal. Pedagang dapat mengatur mengambil keuntungan dan stop loss kelipatan. Stop trailing mengunci lebih banyak keuntungan saat tren berkembang.
Tentukan apakah lilin saat ini memenuhi persyaratan pinbar - tubuh di bagian bawah, dekat dan terbuka dekat rendah. Sinyal panjang adalah kebalikan - tubuh di bagian atas, dekat / terbuka dekat tinggi. Cari lilin sinyal terakhir dan hitung tinggi tubuhnya. Setel ambil keuntungan ke N kali tinggi, dan stop loss ke M kali tinggi (M < N).
Setelah masuk, mulailah mengikuti stop. terus bergerak mengambil keuntungan menuju keuntungan sambil mempertahankan stop loss, sampai salah satu dari keduanya terpukul.
Risiko dapat dikurangi melalui optimasi parameter, penambahan indikator dll.
Strategi ini mengidentifikasi peluang melalui pengenalan pola dengan hasil backtest yang baik. Stop yang wajar mengendalikan risiko perdagangan. penyempurnaan lebih lanjut seperti optimasi parameter dapat membuatnya menjadi sistem yang sederhana dan praktis.
