What Is Forex? How The Currency Market Actually Works
The foreign exchange market explained in plain English — pairs, quotes, who moves price, and the sessions that matter.
What Is Forex?
The foreign exchange market (Forex or FX) is where currencies are bought and sold. It is the largest financial market in the world, turning over trillions of dollars a day.
Unlike a stock exchange, Forex has no central building. It runs through a global network of banks, brokers and electronic platforms, 24 hours a day, five days a week.
When you trade Forex you are always trading a pair — one currency against another. You profit when one strengthens relative to the other.
Currency Pairs: Majors, Minors & Exotics
Pairs are grouped by liquidity and how tightly they trade:
- Majors — always include the US Dollar. EUR/USD, GBP/USD, USD/JPY. Tightest spreads, most liquidity.
- Minors (crosses) — no USD, still liquid. EUR/GBP, EUR/JPY, GBP/JPY.
- Exotics — one major plus an emerging currency. USD/TRY, USD/ZAR. Wide spreads and erratic moves.
How To Read A Forex Quote
A quote looks like EUR/USD = 1.0850. The first currency (EUR) is the base; the second (USD) is the quote.
It tells you how much of the quote currency is needed to buy one unit of the base. If EUR/USD rises, the Euro is strengthening against the Dollar.
You buy a pair when you think the base will strengthen, and sell when you think it will weaken.
Who Actually Moves The Market?
Price is driven by supply and demand, but the volume comes from specific players:
- Central banks — set interest rates and shape monetary policy.
- Commercial & investment banks — the interbank market where most volume happens.
- Hedge funds & institutions — large speculative flows.
- Retail traders — a small slice of total volume.
This hierarchy is why liquidity and "smart money" concepts matter — the big players leave footprints price reacts to.
Market Sessions: When Price Moves
Forex moves through three main sessions as the day follows the sun:
- Sydney / Asia — quieter, often ranges.
- London — huge liquidity, strongest trends.
- New York — overlaps London, high volatility, news-driven.
✅ Key Takeaways
- Forex is a decentralised 24/5 market of currency pairs.
- You trade one currency against another — buy if the base strengthens.
- Majors are the best starting ground.
- London and New York drive most of the volatility.
