The daily turnover of the foreign exchange market is 2.5 trillion US dollars, and the market and data are open. It is an open international market, and the stock market is relatively small, not to mention that a banker or even a national government can not influence the trend of the foreign exchange market, and the stock market is relatively easy to "control" foreign exchange. At the same time, because of the large amount of foreign exchange, there is no situation in the foreign exchange market that the stock market can't trade up or down, and 100% can trade anytime and anywhere.
