Model pembalikan pecahan berdasarkan strategi Pedagang Penyu
ChaoZhang
Gambaran keseluruhan
Strategi ini adalah berdasarkan kepada strategi yang terkenal oleh peniaga-peniaga pelaut, yang telah terbukti selama bertahun-tahun. Ia menghantar isyarat kedudukan panjang dan kosong, dan boleh membuat sehingga 5 pesanan piramid, yang bermaksud bahawa strategi ini boleh mencetuskan sehingga 5 pesanan dalam arah yang sama.
Perlu diperhatikan bahawa strategi ini menggabungkan dua sistem yang bekerja bersama-sama (S1 dan S2).
Prinsip Strategi
Saiz kedudukan sangat penting bagi peniaga pelaut untuk menguruskan risiko dengan betul. Strategi penyesuaian kedudukan ini disesuaikan dengan turun naik pasaran dan akaun (Pendapatan dan Kerugian). Ia berdasarkan ATR (Rangkuman Sebenar Rata-rata), yang juga boleh dikenali sebagai N.
Jumlah unit yang dibeli ialah:
unit = (percentage_to_risk/100)*account/atr*syminfo.pointvalue
Anda boleh menambah peratusan akaun anda mengikut keutamaan risiko anda, tetapi peniaga-peniaga Pantai Merah secara lalai adalah 1%. Jika anda berdagang dengan kontrak, unit mesti secara lalai turun ke bawah.
Terdapat juga peraturan tambahan untuk mengurangkan risiko apabila nilai akaun kurang daripada modal awal: dalam kes ini, dalam formula satuan mesti digantikan dengan formula berikut:
account := (strategy.equity-strategy.openprofit)*(strategy.equity-strategy.openprofit)/strategy.initial_capital
Terdapat dua sistem yang berfungsi bersama: Penembusan adalah kedudukan tinggi atau rendah yang baru. Jika ia adalah kedudukan tinggi baru, kita membuka kedudukan terbalik, sebaliknya, jika ia adalah kedudukan rendah baru, kita memasuki kedudukan kosong.
Kami menambah satu peraturan tambahan: Peraturan tambahan ini membolehkan peniaga untuk mengambil bahagian dalam trend utama, jika isyarat Sistem 1 telah dilangkau. Jika isyarat Sistem 1 telah dilangkau, dan garis K seterusnya juga merupakan penembusan baru pada hari ke-20, maka S1 tidak akan menghantar isyarat. Kita mesti menunggu isyarat S2 atau menunggu tidak menghasilkan garis K baru untuk mengaktifkan semula S1.
Analisis kelebihan
Strategi Pantai membolehkan kita menambah unit tambahan kepada kedudukan apabila pergerakan harga menguntungkan kita. Saya telah mengkonfigurasi strategi untuk membenarkan sehingga 5 pesanan ditambahkan ke arah yang sama. Oleh itu, jika harga berubah dari Beli, kita akan menambah unit.
Kami akan menetapkan pesanan pertama sebagai pesanan maksimum. Perintah piramid seterusnya akan menjadi lebih sedikit unit daripada pesanan pertama.
Kami telah menetapkan maksimum 10% stop loss untuk pesanan pertama anda, yang bermaksud anda tidak akan kehilangan lebih daripada 10% dari nilai pesanan pertama anda.*ATR ((20), pesanan piramid anda mungkin akan kehilangan lebih banyak, dan tidak ada jaminan kerugian tidak melebihi 10%. Risiko masih dikendalikan dengan baik kerana nilai pesanan ini lebih rendah daripada nilai pesanan pertama.
Analisis risiko
Risiko terbesar dalam strategi ini adalah memegang kedudukan yang terlalu besar. Oleh kerana pesanan yang ditugaskan menggunakan harga pasaran, jika beberapa harga pasaran yang besar diturunkan pada masa yang sama, akan memberi kesan besar kepada tawaran dan menyebabkan penurunan besar. Ini akan menyebabkan kerugian besar.
Risiko lain ialah peruntukan pengurusan wang yang tidak sesuai. Peruntukan yang salah atau peruntukan yang terlalu besar boleh menyebabkan kerugian besar. Ini memerlukan peruntukan yang berhati-hati mengikut keutamaan risiko anda.
Arah pengoptimuman
Strategi ini boleh dioptimumkan dalam beberapa aspek:
Anda boleh menguji kesan parameter yang berbeza terhadap kadar pulangan dan kadar Sharpe, seperti kitaran ATR, pengganda ATR yang terhenti, dan sebagainya. Cari kombinasi parameter yang optimum.
Peraturan masuk dan keluar yang berbeza boleh diuji. Sebagai contoh, bentuk garis K digunakan sebagai syarat penapisan tambahan.
Anda boleh mencuba jenis penutupan lain, seperti penutupan bergerak, penutupan dinamik. Ini mungkin dapat mengurangkan kemungkinan penutupan yang ditembusi.
Anda boleh menguji pelbagai jumlah pesanan piramid. Semakin banyak pesanan, semakin besar leverage dan risiko. Cari titik keseimbangan terbaik.
Anda boleh cuba untuk menghentikan perdagangan dalam jangka masa tertentu (seperti sebelum data pekerjaan bukan pertanian AS dikeluarkan) untuk mengelakkan kejatuhan peristiwa besar.
ringkaskan
Secara keseluruhan, strategi ini mempunyai keseimbangan risiko dan keuntungan yang baik, sesuai untuk perdagangan trend panjang dan sederhana. Ia mempunyai kelebihan seperti sistem perdagangan, risiko yang terkawal. Dengan pengoptimuman, kestabilan dan kadar keuntungan strategi dapat ditingkatkan lagi.
