Corak strategi dagangan K-line
ChaoZhang
Gambaran keseluruhan
Ini adalah strategi yang menggunakan bentuk K yang berbeza sebagai isyarat perdagangan. Ia dapat mengesan 9 bentuk yang biasa dijumpai dan menghasilkan isyarat membeli dan menjual berdasarkan bentuk tersebut.
Prinsip Strategi
Logik teras strategi ini adalah untuk mengenal pasti bentuk K-bar yang berbeza, termasuk bintang salib, mata dadu, bintang terang, dan lain-lain. Apabila ia dikenali sebagai bentuk bullish, ia akan menghasilkan isyarat beli; apabila ia dikenali sebagai bentuk bearish, ia akan menghasilkan isyarat jual.
Sebagai contoh, apabila terdapat tiga garis K putih yang naik, ia akan memberi isyarat kepada tiga ekor kuda putih yang naik, yang menunjukkan bahawa pasaran sedang berada dalam trend kenaikan harga, dan ia akan menghasilkan isyarat beli.
Sebagai contoh, apabila satu K yang panjang menelan sepenuhnya satu yang sebelumnya, ia membentuk bentuk beruang IShengulfing, yang menandakan trend berbalik, yang akan menghasilkan isyarat menjual.
Analisis kelebihan
Strategi ini berdasarkan pengenalan bentuk, yang dapat menangkap titik-titik perubahan jangka pendek, sangat sesuai untuk perdagangan garis pendek. Mengenali isyarat bentuk yang tepat, anda boleh menangkap perubahan harga tepat pada masanya, ke arah keuntungan.
Berbanding dengan strategi penunjuk teknikal seperti purata bergerak, strategi bentuk K menggabungkan penilaian mengenai pergerakan harga dan sentimen pasaran, dan isyarat perdagangan lebih tepat dan boleh dipercayai.
Analisis risiko
Strategi ini bergantung kepada penghakiman yang tepat mengenai bentuk garis K. Jika penghakiman yang salah, mudah untuk membentuk isyarat perdagangan yang salah, yang menyebabkan kerugian.
Selain itu, tidak ada strategi analisis teknikal yang dapat sepenuhnya mengelakkan risiko sistemik, seperti kesan dasar, peristiwa Black Swan dan sebagainya yang mungkin memberi kesan kepada perdagangan.
Anda boleh mengawal risiko dengan menghentikan kerugian. Apabila harga melanggar sesuatu julat ke arah yang bertentangan, anda boleh menghentikan kerugian dan keluar tepat pada masanya.
Arah pengoptimuman
Jenis bentuk garis K yang dikenali dapat diperluaskan dengan tambahan beberapa isyarat bentuk yang lebih cekap, seperti garis kerucut, garis kerucut terbalik, garis pemisah, dan lain-lain, yang digunakan untuk mengesahkan isyarat transaksi.
Penapisan boleh dilakukan bersama-sama dengan penunjuk lain untuk mengelakkan isyarat perdagangan dalam keadaan pasaran yang tidak menentu. Isyarat yang dikeluarkan oleh penunjuk seperti MACD, RSI, dan sebagainya dapat mengelakkan isyarat bentuk K yang berkualiti rendah.
Logik berhenti boleh dioptimumkan, berhenti apabila harga menembusi lebar tertentu ke arah yang bertentangan. Bersama-sama dengan indikator kadar turun naik, secara dinamik menyesuaikan ruang berhenti.
ringkaskan
Ini adalah strategi perdagangan garis pendek yang sangat praktikal. Ia mengenal pasti bentuk garis K yang biasa untuk menghasilkan isyarat perdagangan, yang dapat menangkap peluang untuk membalikkan harga dalam jangka pendek. Ia juga memerlukan perhatian terhadap beberapa risiko yang berpotensi dan pengoptimuman yang sesuai untuk mengawal risiko dan meningkatkan kecekapan.
