Question: When can I trade Forex? How are we able to trade 24 hours a day?
You can buy and sell currencies continuously through most of the week.
The exact times depend on your location.
In the UK, for example, you can trade forex from Sunday evening to Friday evening (the exact times vary with clock changes through the year).
The trading day begins in New Zealand and Australia, then moves around the world through Japan and Europe to the USA, with the New Zealanders taking over again as the Americans close down for the night.
