Purata pergerakan mengikut arah aliran dan strategi gabungan corak batang lilin
ChaoZhang
Gambaran keseluruhan
Strategi ini menggabungkan cara untuk menentukan arah trend dengan purata bergerak dan cara untuk menentukan titik balik dengan bentuk garis K. Strategi ini menggunakan purata bergerak untuk menentukan arah trend secara keseluruhan, dan kemudian mencari arah trend dengan bentuk garis K yang berpotensi berbalik sebagai isyarat masuk, untuk mengesan pergerakan trend.
Prinsip Strategi
Strategi menggunakan purata bergerak sederhana dengan panjang 10 hari untuk menentukan arah trend harga. Apabila harga lebih tinggi daripada purata bergerak, ia dianggap dalam trend naik; apabila harga lebih rendah daripada purata bergerak, ia dianggap dalam trend menurun.
Setelah menentukan arah trend, strategi akan menilai titik perubahan trend yang berpotensi berdasarkan serangkaian bentuk K-garis dan K-garis negatif. Bentuk garis positif yang biasa termasuk bintang terang, bintang pagi, tiga tentera putih, dan lain-lain. Bentuk garis negatif yang biasa termasuk bintang senja, tiga burung gagak, dan lain-lain.
Di samping itu, strategi ini juga menggabungkan tahap rintangan sokongan utama untuk menentukan harga masuk. Jika anda membeli di bawah trend menaik, anda akan membeli apabila anda menembusi tahap sokongan pertama.
Kelebihan Strategik
Kelebihan terbesar strategi ini adalah kombinasi penghakiman trend dan isyarat pembalikan pada masa yang sama, yang membolehkannya menangkap titik-titik perubahan trend tepat pada masanya, untuk menjalankan trend. Strategi ini dapat meningkatkan kebarangkalian keuntungan dengan ketara berbanding dengan strategi purata bergerak yang mudah.
Di samping itu, strategi untuk memasukkan penilaian K-line juga meningkatkan keupayaan untuk menangani kejadian yang tidak dijangka. K-line boleh berfungsi sebagai penapis untuk mengelakkan perdagangan yang salah apabila berlaku peristiwa probabiliti rendah yang menyebabkan penembusan palsu di pasaran.
Risiko Strategik
Risiko utama strategi ini terletak pada ketepatan penetapan parameter purata bergerak dan penghakiman bentuk garis K. Jika jangka masa purata bergerak ditetapkan dengan tidak betul, ia boleh menyebabkan kesalahan penghakiman trend; Jika penghakiman bentuk garis K berlaku, ia juga boleh menyebabkan kesalahan keputusan perdagangan.
Di samping itu, bentuk K-baris yang berbalik tidak menjamin 100 peratus bahawa trend akan berbalik, jadi strategi ini mempunyai risiko tertentu. Apabila pasaran berbalik secara lebih luas, ia mungkin membawa kerugian yang lebih besar kepada strategi.
Arah pengoptimuman
Ruang untuk pengoptimuman strategi ini agak besar. Sebagai contoh, parameter untuk menyesuaikan purata bergerak secara dinamik boleh dipertimbangkan, menggunakan kitaran purata bergerak yang berbeza pada peringkat pasaran yang berbeza.
Selain itu, anda juga boleh mempertimbangkan untuk memasukkan lebih banyak faktor untuk menilai trend dan kawasan panas, seperti perubahan jumlah perdagangan, indikator kadar turun naik, dan sebagainya, untuk menjadikan strategi lebih komprehensif dan kukuh.
ringkaskan
Strategi ini secara keseluruhan sangat sesuai untuk mengikuti trend pasaran saham dalam jangka masa sederhana, dan dapat memperoleh pulangan stabil yang tinggi. Jika dioptimumkan lebih lanjut, ia dijangka menjadi strategi kuantitatif yang berfungsi dengan baik. Jika pelabur menguasai penggunaan strategi ini, ia juga dapat digunakan untuk membina portfolio yang dipegang jangka panjang, untuk mengawal risiko saham individu sambil mendapatkan pulangan tambahan yang lebih baik.
