Logika Strategi

Strategi ini menentukan hala tuju trend jangka panjang dengan menganalisis hala tuju pelbagai purata bergerak.

Logikanya ialah:

  1. Mengira purata bergerak untuk tempoh yang berbeza, contohnya 5 hari, 20 hari, 50 hari, dan lain-lain.

  2. Bandingkan kecenderungan arah MA untuk menentukan penyelarasan yang konsisten

  3. Apabila MAs cenderung naik secara seragam, pandangan bullish jangka panjang diadakan.

  4. Dalam keadaan bullish, pecah di atas penurunan stop loss mencetuskan entri panjang

  5. Dalam keadaan menurun, pecah di bawah stop loss menaik mencetuskan entri pendek

  6. Penghentian penghantaran digunakan untuk mengawal risiko

Strategi ini menekankan mengesahkan trend jangka panjang sebelum perdagangan untuk mengurangkan risiko bukan sistematik.

Kelebihan

  • Pelbagai MA menggabungkan untuk menilai arah trend jangka panjang

  • Pendaftaran pecah mengikuti trend

  • Strategi hentian penghantaran mengawal risiko

Risiko

  • MA sendiri ketinggalan harga

  • Penilaian trend yang salah boleh membawa kepada kerugian yang berterusan

  • LONG atau SHORT hanya terlepas peluang

Ringkasan

Strategi ini menekankan menentukan trend sekular melalui arah MA untuk meminimumkan risiko yang tidak sistematik.
