For example, UK stock market hours will not reflect those in Hong Kong or Japan, due to the general difference in work politics and culture. Some stock exchanges also close for a lunch break, mainly those in Asia, whereas they do not in Europe and the Americas.
Stock market hours also vary compared to other financial markets. For example, forex market hours are generally 24 hours a day, from Sunday evening to Friday night. The three major trading sessions include locations in Tokyo (for Asia), London (for Europe) and New York (for North America). The overlap of these trading hours mean that clients are able to open and close positions at most hours within the forex market.
