What is forex trading?

For ordinary person not engaged in Forex trading, it is very easy to explain the definition of Forex with an example of travelling to different countries. When arriving at one country, the first thing to do for a visitor is to exchange the money of his/her country with the currency of the particular country. This process is itself participation in Forex market- exchange one currency for another.

The term Forex stands for the Foreign Exchange and can be defined as an international currency market. Forex is very unique in its essence because it is everywhere neglecting the factor of time zone and geography. In contrast to other physical markets, where monopoly can exist, in Forex market despite the very different market participants, there is no any dominance, and the market remains out of any control.

A question may arise: what is exchanged on Forex? The answer may be quite surprising for you: absolutely “nothing”. All the instruments, including the most popular currencies are not physically exchanged on the foreign exchange market. Market participants just conclude a bet among each other on the currency changes, leaving a margin hundreds times less than the volumes of this betting, and later one participant pays another the sum of the gain (such scheme is known as a margin trading).

The rate of the currency is always changing, fluctuates, and this happens because of different factors. Due to these fluctuations it becomes possible to make a profit from speculative trades. Foreign Exchange is the World’s largest and most active market. It operates every day except the weekends, and its volume reaches up to $5 trillion a day and surely, the volume is different for various participants.
