What is forex?

Forex is Foreign exchange.

It is the opportunity to trade two currencies against each other.
If you think one currency will be stronger than the other, and you end up correct, then you can make a profit.
If you’ve ever traveled to another country, you usually had to find a currency exchange booth at the airport, and then exchange the money you have in your wallet into the currency of the country you are visiting.

The foreign exchange market, which is usually known as “forex” or “FX,” is the largest financial market in the world. The Forex market is a global, decentralized market where the world’s currencies change hands. Exchange rates change every second so the market is constantly moving. Most of the currency transactions that occur in the global foreign exchange market are bought (and sold) for speculative reasons. Currency traders (also known as currency speculators) buy currencies hoping that they will be able to sell them at a higher price in the future.
