The document discusses the foreign exchange (Forex) market. It defines Forex as the trading of currencies between countries. The Forex market is the largest and most liquid market in the world, with over $5.4 trillion traded daily globally. The Forex market is decentralized and operates 24/7, as opposed to traditional stock markets that have set opening and closing times each day. Within the Forex market, there is an ongoing interaction between buyers and sellers, known as bulls and bears, who influence whether currencies rise or fall in value against each other.
