What Is Forex Trading?
Part of the Forex Trading Fundamentals course · 5 min read · Lesson 1 of 1
If you have ever exchanged money at an airport or noticed that prices shift when you shop abroad, you have already experienced the core concept behind forex. The foreign exchange market — forex for short — is where currencies are bought and sold. It is the largest and most liquid financial market on the planet, and it runs almost around the clock.
Currencies are always traded in pairs
Unlike stocks, where you buy shares in a single company, forex always involves two currencies. When you see a quote like EUR/USD 1.0850, it means one euro currently costs 1.0850 US dollars. The first currency in the pair (EUR) is called the base currency, and the second (USD) is the quote currency.
If you believe the euro will strengthen against the dollar, you buy the pair. If the euro does rise — say to 1.0950 — you can sell and pocket the difference. If it falls instead, you take a loss. Every forex trade is essentially a bet on one currency gaining value relative to another.
Who actually trades forex?
The forex market moves over $7.5 trillion every single day — dwarfing the combined volume of all the world's stock exchanges. That volume comes from a wide mix of participants:
- Central banks and governments manage national currency reserves and intervene to stabilise their economies.
- Commercial banks facilitate international trade and handle corporate currency needs.
- Hedge funds and institutional investors speculate on currency movements for profit.
- Corporations convert revenue earned abroad back into their home currency.
- Retail traders — individuals like you — access the market through online brokers.
Why is the forex market so large?
International trade alone requires constant currency conversion. A Norwegian company importing electronics from Japan needs to exchange kroner for yen. A US airline buying fuel priced in dollars still hedges against the currencies of the countries it flies to. Every cross-border transaction feeds liquidity into the forex market.
On top of that, currencies respond to interest rate decisions, inflation data, employment reports, and geopolitical events. This constant flow of catalysts creates opportunities for traders 24 hours a day, five days a week — from the Sydney open on Monday morning to the New York close on Friday evening.
How forex affects everyday life
Even if you never place a trade, forex shapes the prices you pay. A weaker home currency makes imports more expensive — your electronics, fuel, and holiday flights all cost more. A stronger currency does the opposite. Understanding these dynamics gives you a sharper perspective on the economy and on your own finances.
