The times are Broker dependant. Other than change Broker, hence the feed that contains the time, you are stuck with what they provide. I find that +2/3 GMT is the most suitable as it does not produce w/e candles.
Brokers use a variety of timezones. Their local time (with or without DST,) GMT/UTC, GMT+2, NY+7.
Only with NY+7 does the broker's 00:00 equals 5pm ET and the start of a daily bar is the start of a new FX day.
GMT brokers, means there is a 1 or 2 hour D1/H4 bar on Sunday (depending on
NY DST,) and a short Friday bar.
GMT+2 is close but doesn't adjust for NY DST.
EET is closer except when their DST
doesn't match NYs. Last Sunday of March and 1:00 on the last Sunday of October
vs second Sunday in March and return at 2:00 a.m. EDT to
1:00 a.m. EST on the first Sunday in November.
Non-NY+7, means the chart daily
bar overlaps the start, and converting broker time to NY time requires broker to GMT to NY timezone conversions.
