As a forex trader, you buy and sell currencies on a foreign exchange market. Your duties include performing research or analysis on a currency pair. Your responsibilities include finding situations in which a forex transaction has a chance to be profitable and carrying out a purchase on a trading platform. Some forex traders make trades at the request of a client. In these cases, you focus on carrying out the transaction as requested. Forex traders can either work for banks and hedge funds or trade independently. Some traders use charts and math for analysis, while others rely on news and economic data.
