Strategi Perdagangan Kuantitatif Saluran SSL dan Trend Gelombang
Penulis:ChaoZhang, Tarikh: 2024-02-19 11:47:38Tag:
Ringkasan
Strategi ini terutamanya berdasarkan penunjuk Saluran SSL dan penunjuk Trend Gelombang, digabungkan dengan penunjuk tambahan lain, untuk melaksanakan strategi perdagangan kuantitatif yang agak lengkap.
Logika Strategi
Strategi ini mempunyai enam syarat untuk kemasukan, di mana dua yang pertama adalah syarat teras, khususnya:
- SSL Hybrid asas adalah biru (bullish) atau merah (bearish)
- SSL Saluran silang ke atas (bullish) atau ke bawah (bearish)
- Gelombang Trend crossover ke atas (bullish) atau ke bawah (bearish)
- Ketinggian lilin masuk tidak melebihi ambang
- Lilin kemasukan di dalam Bollinger Bands
- Target keuntungan tidak menyentuh EMA
Apabila 6 syarat ini dipenuhi pada masa yang sama, strategi akan pergi panjang atau pergi pendek. Jarak stop loss dikira berdasarkan nilai penunjuk ATR, dan jarak mengambil keuntungan adalah nisbah Anugerah Risiko kali stop loss.
Strategi ini juga mempunyai mekanisme pengurusan risiko dan wang yang baik, termasuk tetapan stop loss, kawalan saiz kedudukan, dan kawalan penarikan maksimum. Pada masa yang sama, strategi menarik garis tambahan pada carta, yang dapat melihat secara visual stop loss dan mengambil keuntungan untuk setiap perdagangan, serta keuntungan dan kerugian tertentu. Ini sangat membantu untuk analisis dan pengoptimuman strategi.
Analisis Kelebihan
Kelebihan terbesar strategi ini adalah bahawa penunjuk Saluran SSL sangat tepat dalam menentukan arah trend. Apabila digabungkan dengan Trend Gelombang dan penunjuk lain untuk pengesahan, ia dapat mengurangkan isyarat palsu. Pada masa yang sama, syarat kemasukan yang ketat juga dapat mengelakkan perdagangan yang tidak perlu, dengan itu mengurangkan bilangan perdagangan dan menurunkan kos transaksi.
Di samping itu, mekanisme pengurusan risiko dan modal strategi yang baik juga merupakan kelebihan yang signifikan. Strategi stop loss dan mengambil keuntungan yang telah ditetapkan sebelumnya dapat mengawal kerugian maksimum perdagangan tunggal dengan berkesan. Bersama dengan kawalan saiz kedudukan, ia dapat menjaga pengeluaran akaun maksimum dalam julat yang boleh diterima.
Analisis Risiko
Risiko terbesar strategi ini adalah bahawa syarat kemasukan yang ketat mungkin kehilangan beberapa peluang perdagangan, mempengaruhi keuntungan.
Di samping itu, keberkesanan Trend Gelombang dan penunjuk lain dalam menentukan trend pasaran juga akan dipengaruhi oleh anomali seperti pecah palsu di pasaran. Pada ketika ini parameter perlu diselaraskan atau penunjuk lain ditambah untuk pengesahan.
Secara keseluruhan, risiko strategi ini masih boleh dikawal. Melalui penyesuaian parameter dan pengoptimuman, strategi boleh dibuat lebih mudah disesuaikan dengan persekitaran pasaran yang berbeza.
Arahan pengoptimuman
Terdapat beberapa arah pengoptimuman untuk strategi ini:
-
Mengoptimumkan parameter Trend Gelombang untuk menentukan titik pembalikan trend dengan lebih tepat
-
Tambah penunjuk lain untuk pengesahan, seperti KDJ, MACD, dan lain-lain, untuk mengelakkan kesan pecah palsu
-
Parameter boleh diselaraskan dan dioptimumkan untuk produk dan jangka masa yang berbeza untuk meningkatkan kestabilan strategi
-
Tambah algoritma pembelajaran mesin untuk melatih model dengan data sejarah dan mengoptimumkan parameter dalam masa nyata
-
Menggunakan faktor kekerapan tinggi dan algoritma lain untuk meningkatkan kekerapan perdagangan strategi dan keuntungan
Melalui pelaksanaan langkah-langkah pengoptimuman ini, ia dijangka membawa keuntungan dan kestabilan strategi ke tahap yang lebih tinggi.
Kesimpulan
Ringkasnya, strategi ini mengintegrasikan pelbagai penunjuk dan mekanisme kemasukan yang ketat untuk memastikan kadar kemenangan yang tinggi sambil mencapai kawalan risiko yang baik.
