What is Forex or Forex market?

The Forex market is a non-stop cash market where currencies of nations are traded, typically via brokers. Foreign currencies are constantly and simultaneously bought and sold across local and global markets and traders' investments increase or decrease in value based upon currency movements. Foreign exchange market conditions can change at any time in response to real-time events.
The purpose of the foreign exchange market is to help international trade and investment. A foreign exchange market helps businesses convert one currency to another. For example, it permits a U.S. business to import European goods and pay Euros, even though the business's income is in U.S. dollars.
In a typical foreign exchange transaction a party purchases a quantity of one currency by paying a quantity of another currency. The modern foreign exchange market started forming during the 1970s when countries gradually switched to floating exchange rates from the previous exchange rate regime, which remained fixed as per the Bretton Woods system.
The foreign exchange market is unique because of

* the extreme liquidity of the market,
* its geographical dispersion,
* its long trading hours: 24 hours a day except on weekends (from 22:00 UTC on Sunday until 22:00 UTC Friday),
* the variety of factors that affect exchange rates.
* the low margins of profit compared with other markets of fixed income (but profits can be high due to very large trading volumes)
* the use of leverage
