HHH -Interested User- Posts: 1 Joined: Aug 29, 2022	Posted: Aug 29, 2022 04:15 AM Msg. 1 of 4 Hello, I am wondering if IqFeed time stamps take into account US daylight saving time, as US markets open at 9:30am EST during the autumn/winter but at 9:30am EDT/8:30am EST during the spring/summer. So I am wondering if: 1. the IqFeed 9:30am time stamp is the opening time for US markets all year long? 2. time stamps are always EST, therefore I need to take take 9:30am during the autumn/winter, and 8:30am during the spring/summer? Thanks Edited by HHH on Aug 29, 2022 at 04:22 AM Edited by HHH on Aug 29, 2022 at 04:30 AM

EG in a 180 historical day request say daylight savings changed 10 days ago would the whole 180 days be adjusted or only the part from 10 days on-wards. Cheers Jon --- nfi what i'm doing, just blunt trial and error
