Dear Rabbi, I am Sephardic. Should: 1) I start[before H sefatai tiftah ofi yagid tehilatecha] Shemoneh Esrei by taking 3 steps back then 3 steps forward? and 2) End[before yihyo leratson imrei fi...] the prayer by taking 3 steps back? I have heard that there are different practices between Ashkenazi and Sephardic when it comes to taking steps in prayer. I just wanted to make sure that I am following this based on halacha. Thank you for your time.

Shalom uvacha, 1. Yes (Rema 95;1, Ben ish chai Beshalach 3, Caf hachaim 95;7). 2.Yes. (Shulchan aruch 123;1). Additional sources: 1. See here: https://ph.yhb.org.il/en/02-17-02/ 2. See here: https://ph.yhb.org.il/en/02-17-13/ All the best!
