Strategi pembalikan trend ideologi dinamik menggunakan harga ramalan regresi linear dan menggabungkan ideologi yang terbentuk dengan purata bergerak untuk menghasilkan isyarat perdagangan. Ia menghasilkan isyarat beli apabila harga ramalan melintasi purata bergerak dari bawah ke atas; ia menghasilkan isyarat jual apabila harga ramalan melintasi purata bergerak dari atas ke bawah, untuk menangkap pembalikan trend.
Isyarat di atas menggabungkan pelbagai pengesahan, mengelakkan penembusan palsu, dan meningkatkan ketepatan isyarat.
Strategi pembalikan trend ideologi dinamik menggabungkan ramalan regresi linear dan pembentukan purata bergerak untuk menangkap masa pembalikan trend. Ia mempunyai kebolehpercayaan yang lebih tinggi berbanding dengan satu petunjuk. Strategi ini dapat meningkatkan kualiti isyarat dan tahap keuntungan dengan penyesuaian parameter dan pengoptimuman syarat pengesahan.
