Although the ability to earn significant profits by using leverage is substantial, leverage can also work against investors. For example, if the currency underlying one of your trades moves in the opposite direction of what you believed would happen, leverage will greatly amplify the potential losses. To avoid a catastrophe, forex traders usually implement a strict trading style that includes the use of stop orders and limit orders designed to control potential losses.
Currencies are traded on the Foreign Exchange market, also known as Forex. This is a decentralized market that spans the globe and is considered the largest by trading volume and the most liquid worldwide. Exchange rates fluctuate continuously due to the ever changing market forces of supply and demand. Forex traders buy a currency pair if they think the exchange rate will rise and sell it if they think the opposite will happen. The Forex market remains open around the world for 24 hours a day with the exception of weekends.
