Ini adalah reka bentuk semula penunjuk SAR Parabolik terbina dalam. Saya menambah sistem input yang betul, pilihan untuk menyerlahkan titik awal untuk kedua-dua garis dan pilihan untuk memilih lebar titik. jadi, sesuaikan seperti yang anda mahu.
SAR Parabolik pada asalnya dibangunkan oleh J. Welles Wilder dan diterangkan dalam bukunya
Untuk mengetahui yang tetapan untuk PSAR adalah yang paling menguntungkan pada instrumen anda dan jangka masa anda boleh menggunakan alat ini
