What Is Forex? A Beginner's Guide to Currency Trading

Foreign exchange (forex, or FX) is the global market where currencies are bought and sold against one another. It’s the largest financial market in the world, with trillions of dollars changing hands every day.

How forex trading works

Currencies are always traded in pairs, because buying one currency means simultaneously selling another. Buying EUR/USD, for example, means buying euros while selling US dollars. If the euro strengthens against the dollar, the value of that pair rises — and a trader holding it profits.

Who trades forex

The market includes central banks, commercial banks, corporations hedging international payments, investment funds, and retail traders. Unlike a stock exchange, forex has no single physical location — trading happens electronically between participants worldwide, almost around the clock on weekdays.

Why prices move

Currency prices react to interest rate decisions, inflation data, economic growth figures, and geopolitical events. Because so many participants respond to the same news, prices can move quickly around major announcements.

Key takeaway

Forex trading means speculating on the relative value of one currency against another. Understanding currency pairs, market hours, and what drives price movement is the foundation for everything else you’ll learn about trading.
