Because foreign exchange trading is an international activity, the main foreign exchange markets are Tokyo, Japan and Australia in the Asia-Pacific region, London, North America, Canada in Europe and new york, the largest trading market in the world. When Asia is closed, it's Europe's turn to go to North America. North America is closed, and going to Asia is almost 24 hours a day.

Unlike the stock and securities markets, trading hours in a country stop on the same day.
