Ringkasan

Strategi ini berdasarkan penyambungan purata bergerak eksponensial berganda (DEMA) sebagai isyarat perdagangan dan mengamalkan pendekatan trend berikut dengan tetapan stop loss dan mengambil keuntungan automatik.

Logika Strategi

Mengira garis DEMA pantas (8 hari), garis DEMA perlahan (24 hari) dan garis DEMA tambahan (boleh dikonfigurasi).
Apabila garisan pantas melintasi di atas garisan perlahan dan isyarat silang emas dihasilkan, pergi panjang. Apabila garisan pantas melintasi di bawah garisan perlahan dan isyarat silang mati dihasilkan, pergi pendek.
Tambah penapis isyarat bahawa isyarat hanya dicetuskan apabila nilai semasa talian tambahan lebih tinggi daripada hari sebelumnya, mengelakkan pecah palsu.
Mengambil trend mengikut mekanisme stop loss di mana garis stop loss terus menyesuaikan berdasarkan pergerakan harga, mengunci keuntungan separa.
Pada masa yang sama menetapkan peratusan stop loss tetap dan mengambil keuntungan untuk mengehadkan kerugian maksimum dan keuntungan setiap perdagangan.

Kelebihan

Isyarat perdagangan yang jelas, mudah untuk menentukan masa masuk dan keluar.
Algoritma DEMA berganda lebih lancar, mengelakkan pemasangan berlebihan, isyarat yang lebih boleh dipercayai.
Penapis talian tambahan meningkatkan ketepatan isyarat, mengurangkan isyarat palsu.
Trend mengikuti kunci stop loss dalam keuntungan separa, mengawal risiko dengan berkesan.
Peratusan tetap stop loss / mengambil keuntungan had kerugian maksimum setiap perdagangan, mengelakkan melebihi toleransi risiko.

Risiko

Perdagangan yang kerap boleh berlaku di pasaran yang berbeza, meningkatkan pendedahan dan menyebabkan kerugian.
Peratusan stop loss tetap yang terlalu besar boleh mencetuskan stop loss besar yang tidak diingini dalam turun naik harga yang melampau.
DEMA tanda crossover lag dan entri panjang pada puncak boleh meningkatkan risiko kerugian dalam pasaran bergerak cepat.
Dalam perdagangan langsung, slippage menjejaskan keuntungan, penyesuaian parameter diperlukan.

Peningkatan

Parameter DEMA boleh dioptimumkan untuk keadaan pasaran yang berbeza.
Pertimbangkan untuk memperluaskan stop loss tetap dalam perdagangan langsung untuk memperhitungkan kos slippage.
Penunjuk lain seperti MACD boleh ditambah untuk meningkatkan kualiti isyarat.
Fine tune tracking stop loss nilai langkah untuk meningkatkan logik.

Kesimpulan

Strategi ini memanfaatkan keupayaan pengesanan trend DEMA dan menggabungkannya dengan metodologi kawalan risiko trend berikut. Ia adalah contoh yang sangat tipikal dalam sistem strategi Arahan Trend. Secara umum ini adalah strategi dengan isyarat yang jelas, konfigurasi stop loss / mengambil keuntungan yang masuk akal dan risiko yang boleh dikawal. Apabila dioptimumkan untuk kos slippage dan ditambah dengan penunjuk tambahan dalam perdagangan langsung, ia dapat mencapai pulangan pelaburan yang baik.
