2. Forex can be referred as Forex exchange trading or as forex or as FX and it involves the buying and selling of one currency, according to its established value against another currency.
3. To make it simple we will understand the same with an example and assume the currency is in Euro and one buy US dollars while its value is weak, and we are doing this with the assumption that sooner or later its value will rise and by reselling it, one would have made some profit.
4. The established value of one currency to another is called exchange rate, which may rise or fall anytime.
Since forex trading is a worldwide market in which governments, national and central banks, hedgefunds, corporate companies, various financial institutions, brokers, and the so called currency speculators all participate, it means that someone is always operating in the market 24 hours a day except on weekends (from 5pm EST on Sunday until 4pm EST Friday), causing the exchange rate to change at any time.
5. One can benefit in this market by virtue of high trading volumes though profit margin will be small. It is based on speculation till the time a central bank do not becomes a reality as rates vary as per the bank and broker trading the same; though the value difference is small. However market is also affected by market psychology, political factors, and economic factors like house prices and employment figures etc.
