Strategi ini menggunakan persilangan purata bergerak cepat dan perlahan untuk menentukan kedudukan panjang dan pendek. Ia menjadi panjang apabila MA cepat melintasi MA perlahan dan menutup kedudukan apabila MA pantas melintasi di bawah MA perlahan. Untuk mengejar keuntungan yang lebih tinggi, strategi ini mengamalkan mekanisme stop loss yang tertinggal. Daripada menetapkan harga stop loss tepat di bawah harga kemasukan selepas membuka kedudukan panjang, ia menetapkan harga stop loss yang tertinggal yang bergerak ke atas berikutan kenaikan harga sehingga penurunan harga mencapai had harga stop loss.
Strategi ini menggunakan garis Purata Bergerak Sederhana (SMA) yang cepat dan perlahan untuk menentukan kemasukan dan keluar. Apabila SMA cepat melintasi SMA perlahan, ia menandakan aliran menaik sehingga strategi menjadi panjang. Apabila SMA cepat melintasi di bawah SMA perlahan, ia menandakan pembalikan trend sehingga strategi bersiap untuk menutup kedudukan.
Untuk memaksimumkan keuntungan, strategi ini memperkenalkan mekanisme stop loss. Daripada menggunakan harga stop loss tetap selepas membuka kedudukan panjang, ia menetapkan harga stop loss yang bergerak ke atas berikutan kenaikan harga. Setiap kali harga meningkat dengan peratusan tertentu, harga stop loss yang diturunkan disesuaikan dengan peratusan yang telah ditentukan. Apabila harga menarik kembali dan mencapai harga stop loss yang diturunkan, ia mencetuskan pesanan stop loss untuk menutup kedudukan.
Khususnya, harga stop loss yang berturut-turut dikira sebagai:
Harga Stop Loss Terakhir = Harga × (1 - Peratusan Stop Loss Terakhir)
Peratusan Stop Loss Trailing ditakrifkan oleh parameter strategi
Apabila harga jatuh dan mencapai harga stop loss yang tertinggal, ia mencetuskan isyarat penutupan dan kedudukan akan ditutup dengan pesanan pasaran.
Strategi ini menggabungkan penunjuk purata bergerak untuk menilai arah trend dan mekanisme hentian kerugian untuk mengunci keuntungan, melakukan dengan baik pada data latihan. Dengan mengoptimumkan parameter dan mengawal risiko, ia mempunyai potensi untuk mencapai keuntungan yang stabil. Walau bagaimanapun, tiada strategi yang dapat mengelakkan kerugian sepenuhnya. Ia disyorkan untuk menyesuaikan saiz kedudukan, menguji produk yang berbeza, dan mempelbagaikan risiko.
