A trader is an individual who engages in the buying and selling of financial assets in any financial market, either for himself or on behalf of another person or institution. A trader mainly differs from an investor by time horizon as a trader would hold assets for a shorter period of time and tends to capitalize on short-term trends. Traders are the most visible human symbols of the financial markets, particularly those working on the diminishing number of face-to-face trading floors. The role is similar to that of a broker, but traders are usually acting on their own behalf while brokers are acting for their clients.
