The Good and the Bad We already have mentioned that factors such as the size, volatility and global structure of the forex market have all contributed to its rapid success. Given the highly liquid nature of this market, investors are able to place extremely large trades without affecting any given exchange rate. These large positions are made available to traders because of the low margin requirements used by the majority of the industry's brokers. For example, it is possible for an investor to control a position of US$100,000 by putting down as little as US$1,000 up front and borrowing the remainder from his or her broker.
