A、The highest price of gold on Asian markets. B、The highest price of gold on African markets. C、The lowest price of gold on Asia

The price of gold fell to its lowest level in five years in trading early Monday. For a time, gold was selling at less than 1 100 dollars an ounce on Asian markets. Some traders are calling the price drop a “mini flash crash.” Thirty billion dollars in short selling took place within half an hour during what are known as “stop-loss” sell-offs. Traders executed sell orders when gold prices reached targets set by investors. The sales manager of a Singapore business that sells gold and other precious metals says, “In the physical market, this would not be possible because that would consume a whole lot of physical gold. But in the futures market, because it’s all digital as long as you find a buyer to bid for it, then that would be possible.”
