Gagasan inti dari strategi ini adalah menggabungkan indikator perbaikan Wix dan regresi liniernya, untuk menangkap titik rendah pasar dengan tepat. Strategi ini disebut strategi perbaikan titik rendah regresi linier.
Proses di atas, menggunakan regresi linier untuk meningkatkan akurasi dan ketepatan waktu sinyal indikator perbaikan Wix, memfilter beberapa sinyal palsu, sehingga tepat menangkap titik rendah.
Strategi ini menggunakan Wix untuk memperbaiki indikator untuk menentukan titik rendah, sementara memperkenalkan regresi linier untuk meningkatkan kualitas sinyal, sehingga dapat menangkap titik rendah pasar secara efektif. Strategi ini sederhana dan praktis, hasilnya lebih ideal, risiko utama adalah kegagalan untuk memfilter sinyal palsu sepenuhnya.
