Ringkasan

Strategi ini berdasarkan idea untuk memecahkan tahap sokongan dan rintangan utama dengan mengenal pasti garis aliran naik dan turun utama dalam carta harga dan perdagangan apabila harga memecahkan garis trend. Strategi ini mudah dan boleh dipercayai, sesuai untuk persekitaran pasaran dengan trend yang jelas.

Prinsip Strategi

Strategi ini mengenal pasti titik tinggi dan rendah utama untuk mendapatkan garis sokongan dan rintangan dengan mengira paras tinggi dan rendah garis bar kiri dan kanan.

  1. Penggunaanpivothigh()danpivotlow()fungsi untuk mengesan puncak dan paras rendah utama.

  2. Keluarkan persamaan untuk garis sokongan dan rintangan berdasarkan paras tertinggi dan terendah.

  3. Pergi panjang apabila harga memecahkan di atas rintangan; pergi pendek apabila harga memecahkan di bawah sokongan.

  4. Pilih panjang atau pendek berdasarkan arah trend.

  5. Pilihan untuk membalikkan kedudukan secara langsung apabila pecah berlaku.

  6. Pilihan untuk menggunakan stop loss, mengambil keuntungan, trailing stop loss.

  7. Pilihan untuk stop loss titik ayunan, ATR stop loss, stop loss tetap.

Strategi dagangan hanya berdasarkan trend line breakouts, keseimbangan trend berikut dan pembalikan, mudah dan praktikal.

Analisis Kelebihan

  • Strategi ini agak mudah, mudah difahami dan dilaksanakan.

  • Menggunakan teori pelarian, mempunyai kelebihan kebarangkalian.

  • Boleh menetapkan stop loss dan mengambil keuntungan untuk mengawal risiko.

  • Boleh melaksanakan trend berikut atau pembalikan.

  • Parameter yang boleh dioptimumkan sesuai dengan persekitaran pasaran yang berbeza.

Analisis Risiko

  • Isyarat keluar mungkin ada isyarat palsu.

  • Penempatan stop loss yang tidak betul boleh meningkatkan kerugian.

  • Perdagangan pembalikan berisiko terperangkap.

  • Penyesuaian parameter memerlukan pengalaman, tetapan yang tidak betul mungkin gagal.

  • Penembusan trend murni tidak sesuai untuk pasaran yang terhad.

Risiko boleh dikurangkan dengan mengoptimumkan strategi stop loss, menilai kualiti isyarat, menilai masa pembalikan dan sebagainya.

Arahan pengoptimuman

  • Menilai kebolehpercayaan isyarat pecah untuk meningkatkan ketepatan.

  • Masukkan bunyi untuk memperkuat isyarat.

  • Mengoptimumkan stop loss untuk turun naik pasaran.

  • Menilai masa pembalikan yang optimum.

  • Penyesuaian parameter.

  • Menilai model pelbagai faktor.

  • Menilai gabungan dengan penunjuk lain.

Ringkasan

Strategi ini adalah mudah dan praktikal secara keseluruhan, menangkap trend harga melalui penembusan trend yang mudah dan risiko yang boleh diurus. Ia boleh dioptimumkan di pelbagai dimensi untuk memenuhi keadaan pasaran yang lebih banyak, trend yang sangat praktikal mengikuti strategi secara keseluruhan.
