After 3 pm until midnight, the European and American markets opened one after another, with a large amount of funds, which fluctuated more than the Asian market in the morning. Specific to the currency pair, the fluctuation of the pound against the dollar in the straight board is the biggest, because the pound is the largest speculative currency in the world, with the most people playing. There are also some crosses that fluctuate violently, so I won't list them here.
