Forex is the market where the world's currencies are bought and sold. If you have ever swapped one currency for another while travelling, you have already made a forex trade — just far smaller than the professionals do. Here's what forex really is, the few terms every beginner needs, and how to start safely.
What "forex" means
Forex is short for foreign exchange. An exchange rate is simply the price of one currency expressed in another. Traders buy and sell based on how they expect those rates to move: if the currency you bought rises, you profit; if it falls, you lose. The market is large, global, and highly liquid, and it runs around the clock on weekdays as trading passes between financial centres worldwide.
Currencies trade in pairs
You never trade a currency alone — always against another, which is why forex is quoted in pairs like EUR/USD or GBP/USD. Each currency has a three-letter code: USD (US dollar), EUR (euro), GBP (British pound), JPY (Japanese yen).
In EUR/USD, the first currency (EUR) is the base and the second (USD) is the quote. The price shows how much of the quote currency it takes to buy one unit of the base. Buying EUR/USD is a bet the euro will rise against the dollar.
Note
Quoting conventions are not uniform. Always check which currency is the base and what a rising number means for your trade before placing it.
Bid, ask, and the spread
Prices show two numbers — a bid and an ask:
- Ask — the price you pay to buy.
- Bid — the lower price you receive when you sell.
The gap between them is the bid-ask spread, a built-in cost of every trade. The wider the spread, the more it costs to get in and out — before any separate commission. That's why low, transparent spreads matter, especially if you trade often.
A pip is the standard smallest price move — for most pairs, the fourth decimal place. If EUR/USD moves from 1.1050 to 1.1051, that's one pip. Pips are how traders measure gains, losses, and spreads consistently.
Leverage and margin
Most forex trades use leverage: putting down a small amount (margin) to control a much larger position. Leverage magnifies price moves — increasing both potential gains and losses. It's the single most important risk for beginners: because currency moves are often small, leverage amplifies them, and a small move against you can wipe out your entire deposit.
Risk
Only risk money you can afford to lose entirely. High leverage can produce large losses relative to your deposit — respect it, don't treat it as a shortcut.
How most people trade forex
Retail traders usually access forex through the off-exchange (OTC) market, trading directly with an online broker rather than on a central exchange. That makes choosing a properly regulated broker one of your most important decisions — it affects your costs, your protection, and your peace of mind.
Getting started the right way
Begin in the right order:
- Learn the basics — you're doing it now.
- Choose a regulated broker — regulation and transparent pricing first.
- Open a demo account — practise with virtual money until your process is consistent.
- Write a simple trading plan — entries, exits, and risk per trade.
- Start small and manage risk — never risk money you can't afford to lose.

The bottom line
Forex is simply the trading of currency pairs, priced by a bid/ask spread, and usually traded with leverage that cuts both ways. Master a few core ideas — pairs, pips, spread, and leverage — practise on a demo, and treat risk management as the foundation. Get those right and every chart will start to make sense.
