The price change of exchange rate in foreign exchange market is mainly caused by the financial activities of banks and foreign exchange exchanges in various regions. Because the working hours in different regions are different, relatively speaking, when a regional center opens every day, its business hours are different. After the business center in a region closes every day, it passes the order to other business centers, which sets the tone for the next market to pass the order from the last center to the next center. These foreign exchange markets are centered on their cities and radiate to other neighboring countries and regions. Due to different time zones, the foreign exchange market is open and closed and listed during business hours. They are interconnected by advanced communication equipment and computer networks, and market participants can conduct transactions all over the world. Foreign exchange funds flow smoothly, and the exchange rate difference between markets is very small, forming a unified international foreign exchange market with global integration and all-weather operation. This leads to what we call the difference in business hours.
