Hello, and welcome to this forum.
It does not depend on where you are located. And it does not depend on the pair.
It depends on a key choice made by the broker you are using, when they set up their trading platform and charts (or leased their trading platform and charts from MetaTrader).
That key choice is: [B]When to open/close Daily candles.[/B]
Once that choice is made, most of the time-frames in the platform are affected.
The time-frames affected by this choice are: all the time-frames from H2 through Monthly. That is, H2, H3, H4, H6, H8, H12, Daily, Weekly and Monthly.
[B]Those time-frames (H2 through Monthly) will all be synchronized with each other.[/B]
That is, if your platform opens/closes Daily candles at 5 pm New York time (for example), then –
• All of the time-frames from H2 through Daily will open a candle at 5 pm New York time. Subsequent candles will open according to their respective time-frame intervals: every 2 hours, every 3 hours, every 4 hours … etc.
• The Weekly candle will open together with [I]the opening of the Monday Daily candle,[/I] and will close together with [I]the closing of the Friday Daily candle.[/I]
• And the Monthly candle will open together with the opening of first Daily candle in the calendar month, and will close together with the closing of the last Daily candle in the calendar month.
H1 (one hour) candles, and all lower time-frames (30-minute, 15-minute, etc.), open/close at [B]the same time in every trading platform,[/B] because hours begin and end at the same time everywhere in the world.
