Bagaimana indikator Parabolic SAR di js menggunakan garis Heiken Ashi k?

Setelah beberapa jam meneliti dan mendapatkan hasil yang sama dengan hasil dari garis k asli, apakah ada batasan apa yang dilakukan talib platform? Jika nilai minimum telah berubah, mengapa nilai sar tetap sama? 2020-02-10 21:35:43 Informasi sar2 9375.691019486052 2020-02-10 21:35:43 Informasi sar1 9375.691019486052 2020-02-10 21:35:43 Informasi 9346.08 9294.560000000001 2020-02-10 21:35:43 Informasi 9346.08 9300
