The Forex market is open 24 hours a day, 5 days a week. So no trading over the weekend.
The time on MT4 is shown as Eastern European Time (EET).
During Daylight-Saving Time, EET is 3 hours ahead of Greenwich Mean Time (GMT +3). During Standard (Winter) Time, EET is 2 hours ahead of GMT (GMT +2).
The end of our trading day always aligns with the market close in New York.
