First, Forex Trading is so popular because of many reasons such as: small dealling costs, the leverage and the high liquidity. In the following, we would like to introduce you to some of the basic concepts of foreign exchange trading.
In Forex Trading is important to use at least 2 currencies: buy dollars > sell euro .. buy euro > sell yen etc.This is also known as carry trading.Another concept of forex trading is margin trading. The exchange is traded on margin and that means you can control better position with only a low deposit. You can even trade 100 times more than your deposit.
You also have to take in consideration some risks. There are lots of people who trade and lose money after a period of time. These risks are: overtrading (before to make trades consider them well), Lack of Knowledge (if you have never used Forex Trading before search for a program,create a demo account and start practice on it) and bad money management.
There are also other concept in Forex Trading but we'll talk about them later.
