Strategi pembalikan trend corak dinamik menggunakan regresi linear untuk meramalkan harga dan garis purata bergerak untuk membentuk corak untuk menjana isyarat perdagangan. Ia menghasilkan isyarat beli apabila harga yang diramalkan melintasi di atas garis purata bergerak ke atas dan isyarat jual apabila melintasi di bawah ke bawah, menangkap pembalikan trend.
Gabungan isyarat di atas dengan pelbagai pengesahan mengelakkan pecah palsu dan meningkatkan ketepatan.
Strategi pembalikan trend corak dinamik mengintegrasikan ramalan regresi linear dan corak purata bergerak untuk menangkap pembalikan trend. Berbanding dengan strategi penunjuk tunggal, ia mempunyai kebolehpercayaan yang lebih tinggi. Penambahbaikan lanjut pada parameter, pengesahan dan pengoptimuman lain dapat meningkatkan kualiti isyarat dan keuntungan.
