Strategi searah bar dengan mengkaji kebarangkalian pergerakan beberapa bar, mengenal pasti isyarat yang muncul dalam trend, melakukan perdagangan terbalik apabila isyarat pembalikan muncul. Strategi ini digunakan terutamanya untuk perdagangan garis pendek tengah.
Strategi ini mula-mula menetapkan masa statistik permulaan dan masa statistik akhir untuk mendapatkan data sejarah. Kemudian menetapkan masa perdagangan untuk mengenal pasti garis K yang memenuhi syarat. Statistik strategi adalah kebarangkalian kenaikan atau penurunan yang sama dari 2 garis K hingga 7 garis K.
Sebagai contoh, strategi menganggarkan kebarangkalian penurunan dalam 3 garis K. Jika kebarangkalian penurunan adalah kurang daripada 50%, maka 3 garis K semasa memenuhi syarat untuk menghasilkan isyarat bullish. Strategi membenarkan parameter statistik untuk 2 hingga 7 garis K.
Secara ringkasnya, logik strategi adalah seperti berikut:
Tetapkan julat masa pengembalian, termasuk tarikh permulaan, tarikh akhir, dan julat masa perdagangan.
Mengira jumlah kenaikan atau penurunan dalam 2 hingga 7 garis K.
Hitung kebarangkalian bahawa bilangan baris K yang berdekatan akan terus meningkat atau menurun.
Jika kebarangkalian kurang daripada 50%, garis K semasa dianggap sesuai dengan bentuk isyarat pembalikan.
Dalam tempoh masa perdagangan, menghasilkan isyarat kenaikan atau penurunan harga.
Melakukan pengesanan semula untuk mengesahkan keberkesanan strategi.
Anda boleh mengurangkan risiko dengan:
Strategi ini boleh dioptimumkan dengan:
Mengoptimumkan bilangan baris K. Ia boleh menguji 2 hingga 10 parameter yang berbeza untuk memilih parameter yang paling optimum.
Optimumkan nilai reversal. 40% hingga 60% parameter yang berbeza boleh diuji, dengan mempertimbangkan perubahan pasaran.
Tambah strategi hentian kerugian. Anda boleh menetapkan titik hentian selepas isyarat terbentuk, mengawal risiko.
Gabungan dengan penunjuk lain. Sebagai contoh, penunjuk seperti RSI boleh digabungkan untuk mengesahkan isyarat pembalikan.
Tambah pelbagai jenis seperti niaga hadapan, forex dan lain-lain. Uji parameter untuk pelbagai jenis perdagangan.
Optimumkan secara beransur-ansur. Sesuaikan parameter secara beransur-ansur untuk mencari kombinasi parameter yang optimum.
Menambah model pembelajaran mesin. Menggunakan algoritma untuk mencari parameter optimum secara automatik.
Strategi pengaliran bar yang sama untuk mengenal pasti isyarat pembalikan yang berpotensi dengan analisis statistik kebarangkalian garis K berganda, mencapai pemprosesan isyarat yang lebih tepat. Tetapi kesan strategi berkaitan dengan pilihan parameter, dan perlu dioptimumkan sepenuhnya. Selain itu, isyarat pembalikan itu sendiri mempunyai kemungkinan kesalahan tertentu, yang perlu disahkan dengan gabungan faktor-faktor lain. Secara keseluruhan, strategi ini adalah strategi statistik yang mudah dan berkesan, yang layak untuk dikaji dan dioptimumkan lebih lanjut.
