A forex trade is an exchange of one currency for another at an agreed price, with the goal of profiting from shifts in the exchange rate

When you trade forex, you are betting that one currency will strengthen or weaken against another. You buy euros with dollars, for example, hoping the euro rises in value so you can sell those euros back for more dollars than you spent. The price you pay and the price you sell at determine your profit or loss. Unlike stocks, where you own a piece of a company, forex trades are pure currency swaps — you never hold the physical money, only a contract that tracks the value.

Forex trades happen in pairs because you always exchange one currency for another. The pair EUR/USD means you are buying euros and selling dollars at the same time. The first currency in the pair is called the base currency, and the second is the quote currency. If EUR/USD is trading at 1.10, that means one euro costs 1.10 dollars. When that rate moves to 1.12, your euros are now worth more dollars, and you can close the trade for a profit.

Key Takeaways

  • A forex trade is a contract to exchange one currency for another at a specific price, with profit or loss depending on how the exchange rate moves after you enter the trade.
  • Forex pairs always show two currencies — the base currency you are buying and the quote currency you are selling — and the price tells you how many units of the quote currency one unit of the base currency costs.
  • Most retail forex traders use leverage, which means borrowing money from their broker to control a larger position than they could afford outright, and leverage magnifies both gains and losses.
  • Forex trades settle in two business days, and you can hold a position for minutes, hours, days, or months depending on your strategy and the broker's rules.
  • The forex market trades around the clock on weekdays across major financial centers, so prices and spreads change constantly throughout the day and week.

How the price quote works in a forex pair

Every forex price shows two numbers: the bid and the ask. The bid is the price a broker will pay you if you sell right now. The ask is the price you pay if you buy right now. The difference between them is called the spread, and it is how the broker makes money on your trade. If EUR/USD is bid 1.1050 and ask 1.1052, the spread is 0.0002 (two pips). You always buy at the ask and sell at the bid, so you start every trade slightly underwater — the price has to move in your favor just to break even.

The smallest price movement in forex is called a pip. For most currency pairs, one pip equals 0.0001 (one ten-thousandth). If you buy EUR/USD at 1.1050 and it rises to 1.1051, you have gained one pip. The dollar value of one pip depends on the size of your position. On a standard lot (100,000 units of the base currency), one pip is worth $10. On a micro lot (1,000 units), one pip is worth $0.10. Brokers let you choose your position size, so you control how much money each pip movement costs or gains you.

What leverage means and why it matters

Most forex brokers offer leverage, which lets you control a large position with a small amount of your own money. If your broker offers 50:1 leverage, you can control $50,000 in currency with $1,000 of your own cash. The broker lends you the rest. This amplifies your returns — a small move in your favor can turn into a large percentage gain on your actual deposit. But leverage also amplifies losses. That same small move against you can wipe out your entire $1,000 and leave you owing the broker money.

The amount of your own money you put up is called your margin. If you use 50:1 leverage and deposit $1,000, your margin is $1,000. Your broker will close your position automatically if your losses eat into your margin too far — this is called a margin call. Different brokers set different margin requirements and leverage limits. Some brokers in the United States offer up to 50:1 leverage, while others in different countries may offer higher ratios. Always check your broker's terms before you trade, because leverage can turn a small mistake into a large loss very quickly.

How long a forex trade lasts

You can hold a forex trade for as little as a few seconds or as long as months or years. Traders who hold positions for seconds or minutes are called scalpers. Those who hold for hours or a day are day traders. Traders who hold for days, weeks, or months are called swing traders or position traders. Your strategy and your broker's rules determine what is realistic for you.

When you close a trade, it settles in two business days. That means the actual currency exchange happens two days after you click the close button. During those two days, your position is still open and exposed to price movement. Most retail traders never see the actual currencies — they close their positions before settlement and move on to the next trade. If you do hold past settlement, your broker will automatically roll the position forward and charge you interest on the borrowed funds, called a swap or rollover fee.

When the forex market is open and how that affects prices

The forex market trades 24 hours a day, five days a week, across major financial centers in Tokyo, London, New York, and Sydney. When it is 9 a.m. in New York, it is already evening in Tokyo and morning in London. This means there is always a market open somewhere, and prices are always moving. The market closes on weekends and does not trade on major holidays, so if you hold a position into Friday evening, you are exposed to any news or events that happen over the weekend without a chance to exit.

Prices and spreads change throughout the day depending on which markets are open and how much trading volume is happening. During the overlap between London and New York (roughly 8 a.m. to noon Eastern time), volume is highest and spreads are tightest. During slow periods like early Asian morning, spreads widen and prices can move more erratically on smaller trades. If you trade during low-volume times, your entry and exit prices may be worse than you expected.

The difference between spot trades and forex contracts

Most retail traders use spot forex, which means you are trading the current market price and settling in two business days. Some brokers also offer forex forwards and forex futures, which are contracts to exchange currencies at a set price on a future date. Forwards are customized contracts between you and the broker, while futures are standardized contracts traded on exchanges. Forwards and futures let you lock in a price far in advance, which is useful if you know you will need a certain currency on a specific date and want to protect against price swings.

For most people starting out, spot forex is the simplest route. You buy and sell at the current market price, and you can exit whenever the market is open. Forwards and futures require more capital and involve different rules, so they are less common for retail traders but more common for businesses that need to exchange large amounts of currency on fixed dates.

Common mistakes when entering a forex trade

One of the biggest mistakes is not accounting for the spread. New traders often see a price on their screen and assume they can buy or sell at that exact price. In reality, you buy at the ask (slightly higher) and sell at the bid (slightly lower). On a volatile pair with a wide spread, the price can move against you when ready just because of the spread, before any real market movement happens. Always check what the spread is on your broker's platform before you trade.

Another common error is using too much leverage too early. A 50:1 leverage position can turn a small account into zero very quickly if the trade moves against you. Many successful traders use 10:1 or even lower leverage until they have proven they can trade profitably. Leverage is a tool, not a shortcut — it magnifies both your skill and your mistakes.

A third mistake is not understanding the settlement date. If you hold a position past 5 p.m. Eastern time on a Wednesday, it will settle on Friday. If you hold it into Friday, it will settle on Monday, and you will pay a weekend swap fee. Some traders accidentally hold positions longer than they intended because they did not realize the settlement rules.

Frequently Asked Questions

Can I make money on a forex trade if the currency goes down?

Yes. You can sell a currency pair first and buy it back later at a lower price. This is called going short or selling short. If you sell EUR/USD at 1.1050 and it falls to 1.1000, you profit from the decline. Most brokers let you go short as easily as you go long, so you can profit in either direction.

What does it mean when a forex pair moves 50 pips in a day?

It means the exchange rate changed by 0.0050 (fifty one-ten-thousandths). On a standard lot, that is a $500 move. On a micro lot, it is a $5 move. Whether that is a big move or a small move depends on the pair and the time period. Some pairs move 50 pips before breakfast; others might take a week to move that much.

Do I have to pay taxes on forex trades?

Yes, in most countries forex trades are taxable. In the United States, forex trades are reported on Form 8949 and Schedule D, and the tax treatment depends on whether you are classified as a trader or an investor. Consult a tax professional about your specific situation, because the rules vary by country and by how frequently you trade.

What happens if my broker goes out of business while I have an open trade?

This depends on where your broker is regulated. Brokers regulated by the SEC or CFTC in the United States are required to segregate customer funds, which means your money is held separately from the broker's operating funds. If the broker fails, your funds should be returned to you. Brokers in other countries have different protections, so check your broker's regulatory status before you deposit money.

Can I trade forex on my phone?

Yes, most brokers offer mobile apps that let you trade from anywhere. However, trading on a phone has risks — you have a smaller screen, slower internet on cellular networks, and it is easier to make mistakes when you are distracted. Many experienced traders avoid phone trading for anything except closing a position quickly in an emergency.
