Jamaica's Usain Bolt earned a double and claimed a record 10th gold medal with a convincing victory in the 200 meters on Thursday at the World Athletics Championships in Beijing, denying rival Justin Gatlin with a time of 19.55.
Foreign exchange markets facilitate the trade of one foreign currency for another. Most exchanges are made in bank deposits and involve U.S. dollars. Over a trillion dollars in foreign exchange trades take place every day; foreign exchange dealers handle most transactions.
One of the key technical differences between the forex markets is the way currencies are quoted. In the forwards or futures markets, foreign exchange always is quoted against the U.S. dollar. This means that pricing is done in terms of how many U.S. dollars are needed to buy one unit of the other currency.
