The Forex Market is the largest traded market it the world
The Foreign Exchange Market, also called the “Forex,” “FX,” 4x,” and “currency market” is a market where one currency is exchanged for another currency. You may see during traveling that there is always a booth in the airport where money can be exchanged. While this is a very inefficient means of exchanging or trading currency, today there are brokerage firms that hold accounts where speculators or traders can trade one currency for another.
