Trade is the transfer of ownership of goods and services from one person or entity to another by getting something in exchange from the buyer. Trade is sometimes loosely called commerce or financial transaction or barter. A network that allows trade is called a market. The original form of trade was barter, the direct exchange of goods and services. Later one side of the barter were the metals, precious metals (poles, coins), bill, paper money. Modern traders instead generally negotiate through a medium of exchange, such as money. As a result, buying can be separated from selling, or earning. The invention of money (and later credit, paper money and non-physical money) greatly simplified and promoted trade. Trade between two traders is called bilateral trade, while trade between more than two traders is called multilateral trade.

Trade exists for man due to specialization and division of labor, most people concentrate on a small aspect of production, trading for other products. Trade exists between regions because different regions have a comparative advantage in the production of some tradable commodity, or because different regions' size allows for the benefits of mass production. As such, trade at market prices between locations benefits both locations.

Tyson Cleotis Chandler (born October 2, 1982) is an American professional basketball center who currently plays for the New York Knicks of the National Basketball Association. Chandler was the second overall pick of the 2001 NBA Draft by the Los Angeles Clippers, then was immediately traded to the Chicago Bulls. He has also played for the New Orleans Hornets, Charlotte Bobcats, and Dallas Mavericks. As starting center for Dallas, he helped win the franchise's first NBA championship in 2011. He was also a member of the United States men's national basketball team's gold medal run in the 2010 FIBA Basketball World Cup.

Chandler was born to a single mother. He and his two brothers, Terrell and Tervon, grew up in their family's farm in Hanford, California, just south of Fresno, California. Chandler began playing basketball at three years old on a basket Chandler's grandfather, Cleotis, fixed on a tree. Chandler grew up doing farm work such as milking cows, slopping pigs, and cultivating crops. At nine years old Chandler and his mother moved to San Bernadino, California; he was already nearly six feet tall. As a child Chandler was teased because of his height; children on his school basketball team joked that he was older than he really was, and that he had been left back several times in school.

Manuel Elias Acta (born January 11, 1969, in San Pedro de Macorís, Dominican Republic) is a Major League Baseball manager for the Cleveland Indians. He is the former manager of the Washington Nationals (2007–2009). In the Dominican Winter League, he managed the Tigres del Licey from 2003–2005, including leading them to victory at the 2004 Caribbean Series. Acta managed the Dominican Republic team at the 2006 World Baseball Classic.

Acta was signed by the Houston Astros at age 17 as a first baseman. He reached Double-A as a backup first baseman and an outfielder at age 20. Acta played baseball professionally for six seasons, all in the Astros' system, but never reached the major leagues as a player. The Astros organization would eventually send him to scouting school in Florida to utilize his analytical skills rather than his athletic talent.

In 1991, Acta became a player-coach at the A level, and soon after that quit his playing career and focused solely on coaching. He became the manager of an A-level team in 1993, and he managed in the minors through 2000. He led the Kissimmee Cobras to a Florida State League championship in 1999.
