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. This amount of leverage acts as a double-edged sword because investors can realize large gains when rates make a small favorable change, but they also run the risk of a massive loss when the rates move against them. Despite the risks, the amount of leverage available in the forex market is what makes it attractive for many speculators.
