Ringkasan

Strategi Multi-Bar Direction mengenal pasti isyarat pembalikan trend dengan mengira kebarangkalian beberapa bar bergerak ke arah yang sama.

Logika Strategi

Strategi ini mula-mula menetapkan waktu permulaan dan akhir untuk pengekstrakan data sejarah. Jam dagangan dikonfigurasi untuk mengenal pasti lilin yang layak. Ia mengira kebarangkalian kenaikan atau penurunan berturut-turut dalam 2 hingga 7 lilin. Isyarat dagangan dihasilkan apabila nisbah naik atau turun melebihi ambang.

Sebagai contoh, jika kebarangkalian trend menurun dalam 3 lilin adalah lebih rendah daripada 50%, 3 lilin semasa memenuhi syarat dan isyarat beli dihasilkan. Parameter dari 2 hingga 7 bar boleh dikonfigurasi.

Logika khusus adalah seperti berikut:

Tetapkan julat masa backtest, termasuk tarikh permulaan, tarikh akhir, jam dagangan.
Hitung jumlah arah yang sama naik atau turun dalam 2 hingga 7 lilin.
Mengira kebarangkalian kelanjutan ke atas atau ke bawah di antara candelabres bersebelahan.
Jika kebarangkalian adalah kurang daripada 50%, lilin semasa sesuai dengan corak pembalikan.
Menghasilkan isyarat beli atau jual dalam waktu perdagangan.
Uji balik untuk mengesahkan strategi.

Kelebihan

Elakkan isyarat palsu dengan mempertimbangkan kemungkinan pelbagai candlestick.
Bilangan bar yang boleh disesuaikan untuk mengenal pasti isyarat pembalikan dalam jangka masa yang berbeza.
Waktu perdagangan yang jelas mengelakkan isyarat yang tidak tepat pada masanya.
Paparan statistik intuitif untuk penilaian prestasi.
Banyak parameter yang boleh dioptimumkan yang sesuai untuk pasaran yang berbeza.

Risiko

Pengiraan bar tidak dapat menentukan titik pembalikan trend.
Tempoh statistik yang panjang mungkin kehilangan peluang perdagangan jangka pendek.
Sempadan statik dipengaruhi oleh turun naik pasaran. penyesuaian dinamik diperlukan.
Pemilihan tempoh ujian belakang boleh menyebabkan pemasangan berlebihan.

Penyelesaian yang mungkin:

Mengoptimumkan bilangan bar untuk jangka masa yang berbeza.
Sertakan penunjuk lain.
Mengambil ambang dinamik berdasarkan turun naik pasaran.
Memperluaskan tempoh backtest dan menjalankan pelbagai backtest.

Arahan pengoptimuman

Strategi ini boleh dioptimumkan dalam aspek berikut:

Mengoptimumkan bilangan bar dari 2 hingga 10 dan pilih parameter yang optimum.
Sempadan pembalikan ujian dari 40% hingga 60% memandangkan perubahan pasaran.
Tambah stop loss selepas penjanaan isyarat untuk mengehadkan risiko.
Masukkan penunjuk lain seperti RSI untuk mengesahkan isyarat.
Tambah lebih banyak produk seperti niaga hadapan dan forex untuk ujian parameter.
Penyesuaian parameter tambahan untuk mencari kombinasi yang optimum.
Gunakan model pembelajaran mesin untuk mencari parameter optimum secara automatik.

Kesimpulan

Strategi Multi-Bar Direction mengenal pasti isyarat pembalikan yang berpotensi dengan menganalisis kebarangkalian candlestick secara statistik. Tetapi prestasi bergantung pada penyesuaian parameter berdasarkan pengoptimuman yang mencukupi. Di samping itu, isyarat pembalikan mempunyai risiko salah menilai dan memerlukan pengesahan. Secara keseluruhan, ini adalah strategi statistik yang mudah dan berkesan yang bernilai untuk penyelidikan dan pengoptimuman lanjut.
