Market Hours
Forex market stays open 24 hours a day, 5 days a week. This is made possible through financial centers changing around the world throughout the day.
The financial centers around the world are in Sydney, Tokyo, London and New York.
Market only stays open 9 am to 5 pm in one area. And in many places the sessions overlap. For example, when the London and New York sessions overlap the market is most volatile and has the highest trade volume.
The cities represent the main financial center for each region, but the names are used interchangeably.
This is how Forex market stays open 24 hours a day. The market closes in one session when the work day ends but by then has started in another.
