Ringkasan

Strategi ini menggabungkan purata bergerak untuk menentukan arah trend dan corak lilin untuk mengenal pasti titik pembalikan yang berpotensi, untuk melaksanakan trend selepas perdagangan.

Prinsip Strategi

Strategi ini menggunakan purata bergerak mudah 10 hari untuk menentukan trend harga. Apabila harga berada di atas purata bergerak, ia dianggap berada dalam trend menaik; apabila harga berada di bawah purata bergerak, ia dianggap berada dalam trend menurun.

Selepas menentukan arah trend, strategi akan menilai titik pembalikan trend yang berpotensi berdasarkan satu siri corak candlestick bullish dan bearish. Corak bullish biasa termasuk Morning Star, Bullish Engulfing, Three White Soldiers, dan lain-lain; corak bearish biasa termasuk Evening Star, Three Black Crows, dan lain-lain. Apabila isyarat bullish dikenal pasti dalam trend menaik, strategi akan meletakkan pesanan beli; apabila isyarat bearish dikenal pasti dalam downtrend, strategi akan meletakkan pesanan jual.

Di samping itu, strategi ini juga menggabungkan tahap sokongan dan rintangan utama untuk menentukan harga kemasukan tertentu.

Kelebihan

Kelebihan terbesar strategi ini ialah ia menggabungkan kedua-dua penilaian trend dan isyarat pembalikan supaya ia dapat menangkap titik perubahan trend dengan tepat pada masanya untuk mengikuti trend.

Di samping itu, penggabungan penghakiman corak candlestick juga meningkatkan keupayaannya untuk menangani peristiwa tiba-tiba. Apabila peristiwa kemungkinan rendah menyebabkan pecah palsu di pasaran, corak candlestick dapat memainkan peranan penapis untuk mengelakkan perdagangan yang salah.

Risiko

Risiko utama strategi ini terletak pada ketepatan tetapan parameter purata bergerak dan penghakiman corak lilin. Jika tempoh purata bergerak ditetapkan dengan tidak betul, ia akan membawa kepada penentuan trend yang salah; jika penghakiman corak lilin mempunyai kesilapan, ia juga akan membawa kepada keputusan perdagangan yang salah.

Di samping itu, corak lilin pembalikan tidak dapat menjamin pembalikan trend dengan kepastian 100%, jadi masih ada beberapa risiko dalam strategi.

Arahan pengoptimuman

Terdapat ruang yang cukup untuk pengoptimuman dalam strategi ini. Sebagai contoh, kita boleh mempertimbangkan penyesuaian parameter purata bergerak secara dinamik dan mengamalkan tempoh purata bergerak yang berbeza di peringkat pasaran yang berbeza. Kita juga boleh memperkenalkan kaedah pembelajaran mesin untuk melatih model penilaian corak lilin menggunakan data sejarah untuk meningkatkan ketepatan penilaian.

Di samping itu, kita juga boleh mempertimbangkan untuk memasukkan lebih banyak faktor untuk menilai trend dan kawasan panas, seperti perubahan jumlah dagangan, penunjuk turun naik, dan lain-lain, untuk menjadikan strategi lebih komprehensif dan kukuh.

Kesimpulan

Secara umum, strategi ini sangat sesuai untuk mengesan trend jangka menengah di pasaran saham dan boleh memperoleh pulangan yang agak tinggi dan stabil. Jika dioptimumkan lebih lanjut, ia berpotensi menjadi strategi kuantitatif yang berfungsi dengan baik. Jika pelabur memahami penggunaan strategi ini, mereka juga boleh menggunakannya untuk membina pegangan jangka panjang untuk mengawal risiko saham individu sambil memperoleh pulangan yang lebih baik.
