Random article: What is Forex?
Forex is an international currency exchange. In accordance with the name, one can immediately determine that the main «products» here are the national currencies.
The structure of the market is somewhat similar to the exchange office. Currency units are sold or bought, taking into account the value positions that exist at the current time. Due to the difference in exchange rates, you can make a significant profit if you buy or sell a certain currency at the appropriate times.
