Strategi ini adalah sistem perdagangan komprehensif yang menggabungkan Garis Isyarat Dinamik (DSL), turun naik, dan penunjuk momentum. Ia secara berkesan mengenal pasti trend pasaran melalui ambang dinamik dan jalur turun naik adaptif, sambil menggunakan penunjuk momentum untuk penapisan isyarat untuk mencapai masa perdagangan yang tepat. Sistem ini menggabungkan mekanisme pengurusan risiko yang lengkap, termasuk sasaran stop-loss dan keuntungan dinamik berdasarkan nisbah risiko-balasan.
Logik teras dibina di atas tiga komponen utama:
Pertama, sistem Garis Isyarat Dinamik mengira garis saluran atas dan bawah dinamik berdasarkan purata bergerak. Garis saluran ini menyesuaikan kedudukan mereka secara automatik berdasarkan kenaikan dan penurunan pasaran baru-baru ini, mencapai penjejakan trend adaptif. Sistem ini juga menggabungkan jalur turun naik dinamik berasaskan ATR untuk mengesahkan kekuatan trend dan menetapkan kedudukan stop-loss.
Kedua, sistem analisis momentum menggunakan penunjuk RSI yang dioptimumkan dengan Purata Bergerak Eksponensial Zero-Lag (ZLEMA).
Ketiga, mekanisme integrasi isyarat. Isyarat perdagangan mesti pada masa yang sama memenuhi kedua-dua pengesahan trend dan keadaan terobosan momentum untuk mencetuskan. Masuk panjang memerlukan terobosan harga di atas jalur atas dan penyelenggaraan di atas saluran, sementara RSI menembusi garis isyarat dinamik bawah. Isyarat pendek memerlukan keadaan yang bertentangan untuk dipenuhi pada masa yang sama.
Strategi ini mencapai penangkapan trend pasaran yang berkesan melalui gabungan inovatif garis isyarat dinamik dan penunjuk momentum. Mekanisme pengurusan risiko yang komprehensif dan sistem penapisan isyarat memberikan nilai aplikasi praktikal yang kuat. Melalui pengoptimuman dan pelarasan parameter yang berterusan, strategi dapat mengekalkan prestasi yang stabil dalam persekitaran pasaran yang berbeza. Walaupun terdapat titik risiko tertentu, mereka boleh dikawal melalui tetapan parameter yang munasabah dan langkah kawalan risiko.
