Hello,

I have been attempting to determine what decides the opening hours of the foreign exchange industry.
EDIT: From opening hours I'm referring to this weekend close/open times.

Once I search I find this:

The industry is available 24 hours each day by 5pm EST on Sunday till 4pm EST Friday. (Investopedia.com)

So that indies Eastern Standard Time is your motorist (New York).
Nevertheless earlier this week that the Forex market started 1 hour later than the prior week (particularly the 30/10/16) yet Daylight Savings period hasn't yet been enforced upon Eastern Standard Time however, that is not until next week (6/11/16). Rather Europe'd DST enforced on the weekend in which they rolled back to operate on GMT 1 (central Europe).

So I'm completely confused. The reference time from the definition utilizes EST.. When their clocks transferred for Daylight Saving, however, the market opening shifted.

Can anybody clear this up for me {}? What's the reference period that is genuine.

Thank you very much.
