How to Trade Forex: A Beginner’s Guide to the Currency Market

Every forex trade is two trades at once. Buy EUR/USD and you have bought euros and sold dollars in the same click. That’s forex trading in one sentence: you exchange one currency for another and profit or lose as the rate between them moves. For a beginner, learning to trade forex comes down to six skills, in this order:

1. Understand what the market is and who you’re trading against.
2. Read a currency pair: base, quote, bid, ask and spread.
3. Work out what a pip is worth for the size you trade.
4. Know what leverage and margin really do to your account.
5. Size every position from a stop-loss, not from your balance.
6. Practise on a demo account, then trade small and keep a journal.

The rest of this guide takes each step in turn, with the numbers worked out.

How the forex market works

Forex (short for foreign exchange, also written FX) is the market where currencies change hands. It’s the largest financial market in the world by a wide margin. In April 2025 it turned over $9.6 trillion a day, according to the Bank for International Settlements’ triennial survey, 28% more than three years earlier.

There’s no central exchange. Forex trades over the counter, through a network of banks, brokers and electronic platforms quoting prices to each other around the world. Banks deal with each other in what’s called the interbank market. Corporations use it to pay foreign suppliers, central banks to manage reserves, funds to hedge overseas holdings. The structure of the forex market explains the layers in more detail.

Retail traders reach this market through a broker. In most cases you don’t take delivery of actual euros or yen. You trade a contract that tracks the exchange rate, usually a CFD (contract for difference), and settle the profit or loss in cash. That’s why a beginner can trade a currency pair with a few hundred dollars: you’re trading the price movement, not moving the currency itself.

One currency dominates everything. The US dollar was on one side of 89.2% of all trades in the 2025 survey. The euro appeared in 28.9%, the yen in 16.8% and the pound in 10.2%. (Each trade involves two currencies, so the shares add up to 200%.) If you trade forex, you are almost always taking a view on the dollar, whether you mean to or not.

How to read a currency pair

Currencies are always quoted in pairs, because a currency only has a price in terms of another currency.

Take EUR/USD at 1.1000. The first currency, the euro, is the base currency. The second, the dollar, is the quote currency. The price tells you how much of the quote currency one unit of the base buys: one euro costs 1.10 dollars.

On a trading screen you never see one price. You see two:

The bid-ask spread is why every trade starts slightly in the red. Buy at 1.1001 and sell straight back at 1.1000, and you’ve lost one pip without the market moving at all. On busy pairs at busy hours the spread is a fraction of a pip. On thinly traded pairs, or in the seconds around a major news release, it can be dozens of pips wide.

Long and short

Buying a pair is going long: you profit if the base currency strengthens against the quote. Selling a pair is going short: you profit if the base weakens.

Selling is no harder than buying. In the stock market, shorting means borrowing shares first. In forex, selling EUR/USD simply means you are long dollars and short euros, which is the same kind of position as any other.

Here’s what that looks like with numbers. You buy 10,000 euros’ worth of EUR/USD at 1.1001. The rate rises to 1.1051, and you sell at the new bid. The pair moved 50 pips in your favour, and on this size each pip is worth $1, so you made $50. Had the rate fallen to 1.0951 instead, you’d have lost $50. Which raises the obvious question: what’s a pip, and why is it worth $1 here?

Pips and lots: what a move is worth

A pip is the standard unit of movement in an exchange rate. For most pairs it’s the fourth decimal place, so EUR/USD going from 1.1000 to 1.1001 is a one-pip move. Pairs involving the Japanese yen are quoted to fewer decimals, and there a pip is the second decimal place: USD/JPY moving from 150.00 to 150.01 is one pip. Many platforms show one more digit, a fractional pip often called a pipette.

Position size in forex is measured in lots, counted in units of the base currency:

Those dollar values hold for any pair where the US dollar is the quote currency: EUR/USD, GBP/USD, AUD/USD, NZD/USD. On other pairs, the pip value comes out in the quote currency and has to be converted. One pip on a standard lot of USD/JPY is 1,000 yen, which at a rate of 150 is about $6.67.

This table is the most useful thing in the article. Once you know that a mini lot of EUR/USD moves $1 per pip, you can translate any chart into money before you place the trade. A 30-pip stop on a mini lot is a $30 risk. The same stop on a standard lot is $300.

Leverage and margin

A mini lot of EUR/USD at 1.1000 is a position worth $11,000. Few beginners put $11,000 into one trade, and with leverage, they don’t have to.

Leverage lets you control a position larger than the money you put up. The money you put up is the margin: a deposit the broker sets aside while the trade is open. Leverage is written as a ratio:

Look at the last column. The pip value is the same in every row. Leverage changes how much cash the broker locks up. It doesn’t change how much you gain or lose per pip. That’s set entirely by position size.

This is where most beginners get it backwards. High leverage feels dangerous, so they think the fix is lower leverage. But the danger is the position size that high leverage makes possible. With 1:500 available, a $200 account can open a $50,000 position. At $5 a pip, a 40-pip move against it, well under half a percent on EUR/USD, wipes the account out.

Regulators have reached the same conclusion. Since 2018, brokers serving retail clients in the EU and UK have been limited to 1:30 on major currency pairs. Elsewhere, offshore brokers commonly offer far more. Whatever the ceiling, treat it as a limit on what the platform allows, not a suggestion.

When losses eat into your margin, the broker issues a margin call, a warning that your account is running out of room. If the losses continue, it reaches the stop-out level and the platform starts closing your positions automatically, at whatever price the market offers.

Major, minor and exotic pairs

Brokers list dozens of currency pairs, and they sort into three groups.

Major pairs pair the US dollar with another heavily traded currency: EUR/USD, USD/JPY, GBP/USD, USD/CHF, USD/CAD, AUD/USD and NZD/USD. The last three are often called commodity pairs, because those economies lean on exports of raw materials. The Canadian dollar tends to track oil, while the Australian and New Zealand dollars react to metals, farm exports and demand from China.

Minor pairs, or crosses, combine two major currencies without the dollar: EUR/GBP, EUR/JPY, GBP/JPY, AUD/NZD.

Exotic pairs combine a major currency with one from a smaller or emerging economy: USD/TRY, USD/ZAR, USD/MXN, EUR/PLN.

The difference that matters to a beginner is liquidity. Majors trade in enormous volume, so spreads are narrow and prices move in small steps. Exotics trade far less, so spreads can be many times wider, and the currencies can jump sharply on local politics or a central bank surprise. Starting on one or two majors means your costs are lowest and the news that moves the price is the news everyone is covering. The most volatile currency pairs are worth reading about later, once you know how your own trading behaves.

When the forex market is open

Forex trades 24 hours a day, five days a week. The week opens on Sunday evening GMT, when trading starts in Sydney, and closes on Friday evening when New York shuts. At weekends the market is closed, and prices can open on Sunday some distance from where they closed on Friday.

Activity moves around the globe in four overlapping sessions:

Exact times shift by an hour when the UK, US and Australia change their clocks, and sources draw the session edges slightly differently.

The London session carries the largest share of daily volume, and the four hours when it overlaps with New York, roughly 13:00 to 17:00 GMT, are usually the busiest of the day. That’s when spreads on the majors tend to be narrowest. The quiet hours after New York closes are the opposite: thin trading, wider spreads, and occasional sharp moves on little volume.

What moves exchange rates

A share price reflects one company. An exchange rate reflects two whole economies, and the gap between them. Five forces do most of the work.

Interest rates. Money tends to flow toward the currency that pays more interest. When one central bank raises rates while another holds, the gap between them, the interest rate differential, widens, and the higher-yielding currency usually strengthens. This is the single biggest long-run driver of most major pairs, and the reason central bank meetings move markets more than almost anything else.

Inflation. Inflation erodes what a currency buys. But the market reacts less to inflation itself than to what the central bank is expected to do about it. A higher-than-expected inflation figure can lift a currency, if traders read it as a sign that rate hikes are coming.

Economic data. Employment, growth, retail sales and business surveys all feed into expectations for interest rates. The best-known is the US non-farm payrolls report, usually released on the first Friday of the month, which can move every dollar pair within seconds of publication.

Risk sentiment. When investors are nervous, money tends to move into safe-haven currencies, traditionally the US dollar, the Japanese yen and the Swiss franc. When they’re confident, it flows toward higher-yielding currencies such as the Australian dollar.

Politics and policy shocks. Elections, trade disputes and government debt scares can override everything else for days at a time. Occasionally a central bank changes the rules outright, which is the risk the stop-loss section below comes back to.

Almost all scheduled events appear on an economic calendar days in advance. Checking it before you open a position is the cheapest risk control there is.

Two ways to analyse a currency pair

Traders form a view on a pair in two broad ways, and most use some of both.

Fundamental analysis is everything in the section above: reading interest rates, data and politics to judge where a currency should be heading. It works best for answering “which direction, over weeks or months?”

Technical analysis reads the price chart itself. A technical trader looks at trends, support and resistance (price levels where buying or selling has repeatedly stepped in), chart patterns and indicators. Candlestick charts are the standard starting point: each candle shows the open, high, low and close for one period, so a single glance tells you who won that hour or day, buyers or sellers. Technical analysis is better at answering “where exactly do I get in, and where do I admit I’m wrong?”

That second question matters more than the first. A trader can be wrong about direction half the time and still do well, if the losing trades are small and the winning ones are larger. That only works with a stop-loss, placed at a level that means something on the chart. Forex trading strategies covers specific approaches once the basics are in place.

What a forex trade costs

Three costs can apply, depending on the broker and the account. Before you trade, find out which ones you’re paying.

The spread is paid on every trade, built into the gap between bid and ask. It’s the main cost for short-term traders.

Commission is a separate fee per trade or per lot. Some accounts charge no commission and earn from the spread; others offer narrower spreads plus a commission.

The swap, also called rollover or overnight financing, applies to positions held past the daily cut-off. It reflects the interest rate difference between the two currencies, so it can be a charge or a credit depending on the pair and the direction you hold. A day trader rarely notices it. A trader holding positions for weeks can find it adds up to more than the spread. Some brokers offer swap-free accounts for traders who can’t pay or receive interest for religious reasons. The spread vs commission vs swap guide compares the cost models side by side.

Risk management: size from the stop

The single habit that separates traders who last from those who don’t is how they decide position size. Beginners usually start from their balance: “I have $1,000, so I’ll trade a mini lot.” The order should be reversed.

1. Decide how much you’ll risk on the trade. A common rule is 1% to 2% of the account. On $1,000, 1% is $10.
2. Decide where the stop-loss goes. Put it at a level that proves your idea wrong, such as just beyond a recent high or low, not at a round number of dollars. Say that’s 25 pips away.
3. Divide the risk by the stop. $10 ÷ 25 pips = $0.40 per pip.
4. Convert that to a size. On EUR/USD, $0.40 per pip is 4,000 units, or 0.04 lots.

That’s your position size. Leverage played no part in the calculation. It only decides whether your account has enough margin to open the trade at all.

Then set a take-profit at least as far away as the stop. With a 25-pip stop and a 50-pip target, one winning trade pays for two losers, and you can be wrong more often than right.

What a stop-loss can’t do

A stop-loss is an instruction to close the trade at the next available price once your level is reached. In a normal market, that’s at or near your level. In a fast one, the next available price can be far beyond it.

The clearest example is 15 January 2015. That morning the Swiss National Bank abandoned the 1.20 minimum exchange rate it had held against the euro since 2011. The franc rose more than 20% against the euro that day. There was barely any market between the old price and the new one, so stop-losses placed just below 1.20 were filled hundreds of pips lower. Some traders lost more than their entire deposit.

Events on that scale are rare. Smaller gaps are not: they happen around central bank decisions, major data releases and the weekend open. That’s why position size, not the stop-loss alone, is the real protection, and why it pays to check whether a broker offers negative balance protection, which caps your loss at the money in the account. The guide to risk management strategies goes further.

Forex vs stocks: what’s different

If you’ve invested in shares, four things will feel different.

The last row is the one to remember. Currencies usually move less in a day than individual shares, so brokers allow more leverage on them. That makes forex feel slow until you’re trading a position large enough to make the small moves count, and then it’s anything but.

How to start trading forex: your first trade

Put the pieces together and the path from zero to a first live trade looks like this.

1. Learn the vocabulary. Pairs, pips, lots, spread, leverage and margin, as above. If any of those still feels fuzzy, the guide to what forex trading is covers the background.
2. Choose a broker carefully. Look at how it holds client money, what happens if your account goes negative, what the full costs are on the pairs you want to trade, and whether its platform is one you can use comfortably. The checklist in how to know if a broker is legit is a good place to start.
3. Practise on a demo account. Most brokers offer one, funded with virtual money and running on live prices. Place 20 or 30 trades there. The point isn’t to win. It’s to learn where the buttons are, how a stop-loss behaves, and what a losing streak feels like before it costs anything.
4. Write a plan. One or two pairs, the hours you’ll trade, the risk per trade, the conditions that get you into a trade and out of it. If it isn’t written down, it isn’t a plan.
5. Go live small. Trade micro lots. The first months of live trading teach you about your own reactions, and that lesson is the same at $0.10 a pip as at $10.
6. Keep a journal. Pair, direction, entry, stop, target, reason, result. After 50 trades it will show you patterns no article can.

The mistakes that end most first accounts are predictable: sizing from the balance instead of the stop, moving a stop-loss further away as price approaches it, trading straight through a major data release, and doubling up after a loss to win it back. The list of typical margin trading mistakes covers each one. Every one of them is a position-size problem in disguise.
