Forex trading for beginners: how it works

Forex trading means buying one currency while selling another, betting on how their exchange rate will move. This guide covers the basics you need before risking any money: how prices work, what a trade costs and why leverage makes it risky.

What the forex market is

The foreign exchange market is where currencies are bought and sold. It is the largest financial market in the world: the Bank for International Settlements measured average turnover of about $9.6 trillion a day in April 2025. Most of that is banks, companies and funds; retail traders are a small share.

Retail traders usually access it through a broker, trading contracts that track exchange rates rather than exchanging physical currency.

How a currency pair works

Every trade involves two currencies. In EUR/USD at 1.1000, one euro costs 1.10 US dollars. If you buy EUR/USD, you profit if the euro strengthens against the dollar; if you sell, you profit if it weakens. See currency pairs explained.

What a trade costs

You pay the spread, the gap between the buy and sell price, every time you open a trade. Some accounts add a commission per lot, and positions held overnight are charged or paid a swap. See spreads and commissions and swap rates.

Leverage and risk

Leverage lets you control a large position with a small deposit, so small price moves become large gains or losses. Regulators in the UK, EU and Australia require brokers to warn that most retail CFD accounts lose money, and to publish the percentage for their own clients.

Start by learning what a pip is worth and how to size a position, so you know the money at risk before each trade.

Next steps: work out how much money you need to start, learn how lot sizes set your risk, and pick a trading style that fits your time.
