Ringkasan

Strategi ini mengira purata bergerak pantas dan perlahan untuk menentukan trend. Ia pergi lama apabila purata bergerak pantas menyeberangi purata bergerak perlahan, dan menetapkan stop loss yang dinamik untuk mengunci keuntungan apabila harga berubah dengan peratusan tertentu.

Logika Strategi

Strategi ini menggunakan salib emas purata bergerak pantas dan perlahan untuk menentukan permulaan trend menaik. Khususnya, ia mengira purata bergerak mudah harga penutupan dalam tempoh tertentu, membandingkan nilai purata bergerak pantas dan perlahan, dan menilai permulaan trend menaik apabila purata bergerak pantas melintasi yang perlahan.

Selepas membuka kedudukan panjang, strategi ini tidak menetapkan stop loss tetap, tetapi menggunakan stop loss trailing dinamik untuk mengunci keuntungan. Garis stop loss ditetapkan berdasarkan: Harga Tertinggi * (1 - Peratusan Stop Loss). Ini membolehkan garis stop loss bergerak ke atas apabila harga meningkat. Apabila harga jatuh sebanyak peratusan tertentu, stop loss akan dicetuskan untuk keluar dari kedudukan.

Kelebihan pendekatan ini adalah bahawa ia membolehkan mengejar aliran menaik tanpa had, sambil mengunci keuntungan apabila mereka mencapai tahap tertentu melalui stop loss.

Analisis Kelebihan

Kelebihan utama strategi Stop Loss ini ialah:

Ia membolehkan mengejar trend tanpa had tanpa ketinggalan pergerakan besar.
Ia mengunci keuntungan dengan menetapkan peratusan stop loss. Hanya mengejar trend tanpa stop loss boleh membawa kepada kerugian apabila trend berakhir. Stop loss mengunci keuntungan.
Ia lebih fleksibel daripada stop loss tetap. Stop stop tetap hanya boleh ditetapkan pada satu harga, manakala stop loss ini bergerak dengan harga tertinggi.
Ia mempunyai risiko menarik balik yang lebih rendah. Hentian tetap sering jauh dari harga tertinggi, yang membawa kepada hentian awal pada hentian normal. Hentian kerugian ini kekal dekat dengan harga tertinggi untuk mengelakkan hentian yang tidak perlu.

Analisis Risiko

Strategi ini juga mempunyai beberapa risiko:

Penunjuk yang digunakan untuk isyarat masuk mungkin tidak stabil dan menghasilkan isyarat palsu.
Hanya ada satu pendekatan stop loss tanpa mengambil kira faktor lain. Perubahan pasaran yang besar boleh membatalkan strategi.
Tidak ada sasaran keuntungan, hanya bergantung pada stop loss. Stop loss yang tidak berkesan boleh menyebabkan kerugian besar.
Parameter seperti tempoh purata bergerak memerlukan pengoptimuman lanjut.

Arahan pengoptimuman

Strategi ini boleh ditingkatkan dalam beberapa bidang:

Tambah lebih banyak penunjuk untuk mengesahkan entri dan mengelakkan isyarat palsu, contohnya jumlah.
Tambah mengambil keuntungan apabila keuntungan mencapai peratusan tertentu.
Meningkatkan keselamatan stop loss dengan menyesuaikan jarak berhenti secara dinamik dalam peristiwa pasaran yang luar biasa.
Mengoptimumkan parameter seperti instrumen dagangan dan sesi dagangan.
Tambah pembelajaran mesin untuk menyesuaikan parameter secara dinamik dan mengoptimumkan penunjuk dan tahap stop loss secara automatik.

Ringkasan

Logik keseluruhan strategi ini adalah baik dan munasabah. Menggunakan purata bergerak cepat dan perlahan untuk menentukan trend adalah pendekatan klasik. Stop loss yang mengikuti juga berkesan untuk mengunci keuntungan dan mengurangkan risiko. Walau bagaimanapun, ujian dan pengoptimuman berterusan diperlukan untuk penunjuk dan parameter untuk menjadikan strategi secara konsisten menguntungkan. Pada masa yang sama, perubahan pasaran utama yang boleh membatalkan strategi perlu dijaga dengan meningkatkan logik dan rangka kerja keseluruhan dan menambah perlindungan.

//  Description
//  =============================================================================
//  This strategy will go long if fast MA crosses over slow MA.
//  The strategy will exit from long position when the price increases by a fixed percentage.
//  If the trailing take profit is checked then the strategy instead of setting a limit order in a predefined price (based on the percentage)
//  it will follow the price with small steps (percentagewise)
//  If the price drops by this percentage then the exit order will be executed
//
//  The strategy has the following parameters:
//
//  Fast SMA Length - How many candles back to calculte the fast SMA.
//  Slow SMA Length - How many candles back to calculte the slow SMA.
//  Enable Trailing - Enable or disable the trailing.
//  Stop Loss % - The percentage of the price decrease to set the stop loss price target for long positions.
