Forex Trading for Beginners: How It Works, What It Costs, the Risks

What is forex trading?

Forex (short for foreign exchange) is the market where people swap one currency for another. If you have changed US dollars into euros for a trip, you have used it.

Imagine you swap $1,100 for 1,000 euros before a trip to Europe. While you are away, the euro gets stronger. Your 1,000 euros are now worth more dollars than you paid. Forex traders try to profit from moves like this, in either direction.

There is one big difference. Travel money gives you euros to spend. Retail forex trading often uses a contract that only pays the change in price. You may never own a single euro. Banks, companies and central banks also trade currencies, for their own reasons. See who trades forex.

The rules depend on where you live. In the US, retail forex is traded with a dealer, and the CFTC explains the risks. In Australia, ASIC Moneysmart explains margin forex. In Canada and the UK, check what product you are buying and who provides it.

How do I read a forex price?

Every forex price compares two currencies. EUR/USD 1.1000 means 1 euro costs 1.10 US dollars. When you buy EUR/USD, you buy euros and pay with dollars. You gain if the euro gets stronger.

Prices move in small steps called pips. For most pairs, 1 pip is 0.0001. For pairs with the Japanese yen, it is 0.01. If you hold 10,000 euros of EUR/USD, each pip is worth $1.

Trade size is often shown in lots. A standard lot is usually 100,000 units of the first currency. Many brokers offer smaller sizes too. Always check the size on your screen. One "unit" in an app does not always mean one euro.

Your next lesson shows how to read any pair out loud: how to read currency pairs.

What does a forex trade cost?

Every pair has two prices. The bid is the price you can sell at. The ask is the price you can buy at. The gap between them is the spread, and you pay it on every trade.

So every trade starts a little behind. The price must move in your favour by the spread before you break even.

Other costs can add up. Some accounts charge a commission per trade. Holding a trade overnight can add a financing charge. A "zero spread" account may charge commission instead. Compare the full cost for the same pair and trade size. The spread lesson shows how.

How does leverage change the risk?

Leverage lets you open a trade much bigger than the money in your account. Say you have $1,000 and open a $20,000 trade. That is 20:1 leverage.

Now the price moves 1% against you. You lose 1% of $20,000, which is $200. That is 20% of your money from one small move. The same works for gains, but losses can come just as fast.

The margin is the part of your money the broker locks while the trade is open. It is not the most you can lose. Limits also depend on where you live. For major pairs, US dealers can offer up to 50:1. In the UK, EU and Australia, retail CFD accounts are capped at 30:1. Learn more in margin vs leverage.

Watch for hidden doubling, too. If you buy EUR/USD and also buy GBP/USD, both trades are bets against the US dollar. One dollar move can hit both trades.

Which order types should a beginner know?

An order is your instruction to the broker. Here are the 3 basic types:

A stop-loss order closes your trade if the price moves against you to a set level. It is a useful tool, but not a promise. If the price jumps past your level, for example after a weekend, the trade can close at a worse price.

Check which price triggers your stop. Some platforms use the bid, others the ask. Your broker's terms decide what really happens.

How much should I risk on one trade?

Plan the loss before you think about the profit. A common guideline is to risk no more than 1% of your account on one trade. With $2,000, that is $20. This is a habit some traders use, not a rule that makes trading safe.

Costs and price jumps can make the real loss bigger. And if your broker's smallest trade is too big for your plan, the trade does not fit. Do not stretch the plan to make it fit.

Only ever trade with money you can afford to lose. Never use money you need for rent, food or bills.

What should I learn next?

Learn in this order. Each step builds on the one before:

1. Read a pair and its units: currency pairs.
2. Know when markets are open and when prices can jump: market hours.
3. See what moves currencies: exchange rate drivers.
4. Work out costs: the spread.
5. Read a forex chart and write one rule clearly.
6. Test that rule honestly: backtesting.

Practise with virtual money first. Write down the pair, size, costs, stop and reason before each practice trade. Practice results do not prove you would make money with real trades.

Many brokers offer the same trading app, made by another company, such as MetaTrader. The app is not the broker. Before you send any money, use the broker checklist and compare licensed providers in our forex broker guide. And remember: learning forex does not mean you have to trade it.
