Forex trading is nothing more than direct access trading of different types of foreign currencies. In the past, foreign exchange trading was mostly limited to large banks and institutional traders. However recent technological advancements have made it so that small traders can also take advantage of the many benefits of forex trading just by using the various online trading platforms to trade.

The currencies of the world are on a floating exchange rate, and they are always traded in pairs. About 85 percent of all daily transactions involve trading of the major currencies. Four major currency pairs are usually used for investment purposes. They are: Euro against US dollar (EUR/USD), US dollar against Japanese yen (USD/JPY), British pound against US dollar (GBP/USD) and US dollar against Swiss franc (USD/CHF).

If you think one currency will appreciate against another, you may exchange that second currency for the first one and be able to "stay" in it. If everything goes as you plan it, eventually you may be able to make the opposite deal in that you may exchange this first currency back for that other and then collect profits from it. As a note bear in mind that no dividends are paid on currencies.
