What happens when you trade currencies

Forex trading means buying one currency while selling another at the same time. When you trade, you are betting that the price of one currency will move against another. For example, if you buy euros and sell US dollars, you are betting the euro will become more valuable relative to the dollar. If it does, you sell your euros back and keep the difference. If the euro weakens instead, you lose money.

The forex market operates 24 hours a day across major financial centres — Tokyo, London, New York — so currency prices move constantly. Unlike stock markets, which have set opening and closing times, forex never fully closes. This means prices can shift while you sleep, and positions you hold overnight carry risk from market moves you cannot watch.

Most forex trades happen between banks and large financial institutions, but retail traders can access the market through a broker — a company that gives you a platform to place trades and holds your money. The broker acts as the middleman between you and the larger market.

Key Takeaways

  • Forex trades always involve two currencies at once: you buy one and sell the other, betting on how their relative value will change.
  • Currency prices move based on economic data, interest rates, political events, and supply and demand, not on company performance like stocks do.
  • Most retail traders use leverage, which means borrowing money from their broker to control larger positions than their account balance allows, and leverage multiplies both gains and losses.
  • The forex market is open 24 hours a day across different time zones, so prices move constantly and positions held overnight face overnight risk.
  • A broker provides the platform and holds your money, but you are responsible for your own trading decisions and losses.

Currency pairs and how prices are quoted

Every forex trade involves a pair of currencies written as a ratio, like EUR/USD. The first currency is the base currency and the second is the quote currency. When you see EUR/USD = 1.10, it means one euro costs 1.10 US dollars. If you buy this pair, you are buying euros and selling dollars. If you sell it, you are selling euros and buying dollars.

The price moves in small increments called pips. A pip is usually the fourth decimal place in a currency pair — so if EUR/USD moves from 1.1050 to 1.1051, that is one pip. On some pairs involving the Japanese yen, a pip is the second decimal place instead. Each pip represents a tiny fraction of a cent per unit, but because traders control large amounts of currency, small pip movements add up to real money.

The difference between the price a broker will pay you (the bid) and the price they will charge you to buy (the ask) is called the spread. This is how brokers make money. A tight spread of 1 to 2 pips is common for major pairs like EUR/USD. Exotic pairs involving smaller currencies may have spreads of 10 pips or more, making them more expensive to trade.

What moves currency prices

Currency values change based on economic conditions and expectations about the future. When a country's central bank raises interest rates, investors want to hold that currency to earn higher returns, so demand rises and the currency strengthens. When economic data shows a country is slowing down, investors sell that currency, and it weakens.

Political events, trade disputes, and unexpected news can cause sharp price moves. A country's inflation rate, employment figures, and GDP growth all affect how traders value its currency. Because these data points are released on a schedule, experienced traders watch an economic calendar to know when major announcements are coming.

Supply and demand also matter. If many traders want to buy a currency at once, its price rises. If many want to sell, it falls. This is why large trades by banks or sudden news can cause price spikes. Unlike stocks, which represent ownership in a company, currencies have no intrinsic value — they are worth only what someone else will pay for them right now.

Leverage and how it amplifies gains and losses

Most retail forex traders use leverage, which means borrowing money from their broker to control a larger position than their account balance allows. If your broker offers 50:1 leverage, you can control $50,000 in currency with only $1,000 of your own money. This sounds attractive because small price moves can produce large percentage gains on your account.

The problem is that leverage also multiplies losses. If the market moves against you by just 2 percent, your entire $1,000 is gone. Many traders lose their account balance in a single bad trade because they did not understand how fast leverage can wipe out money. Brokers in the United States are limited to 50:1 leverage for major currency pairs, but brokers outside the US may offer much higher leverage — sometimes 100:1 or more — which increases the risk of total loss.

Leverage is optional. You can trade without it by using only the money in your account. This means your maximum loss is the amount you deposited, but your gains are also smaller. Many new traders find this approach safer because it forces them to think about position size before they trade.

How orders and positions work

When you place a trade, you choose how much currency to buy or sell and at what price. A market order executes immediately at the current price. A limit order only executes if the price reaches a level you set in advance — useful if you want to buy only if the price drops to a certain point. A stop-loss order automatically closes your position if the price moves against you by a set amount, limiting your loss.

Once you open a position, it stays open until you close it by trading in the opposite direction. If you bought EUR/USD, you close the position by selling EUR/USD. The difference between your entry price and exit price, minus the spread and any fees, is your profit or loss. Some brokers charge a commission per trade; others make money only from the spread.

You can hold a position for seconds (scalping), minutes or hours (day trading), or days or weeks (swing trading). Each approach has different risks. Holding overnight exposes you to price gaps when the market reopens, especially around major economic announcements or on Sundays when markets reopen after the weekend.

The role of brokers and trading platforms

Your broker provides the software platform where you place trades, view charts, and manage your money. They also hold your account balance and execute your orders. Not all brokers are regulated equally. In the United States, brokers must be registered with the National Futures Association (NFA) and the Commodity Futures Trading Commission (CFTC). In Europe, brokers must be regulated by their national financial authority. Brokers outside these regions may have little to no oversight.

Regulated brokers must follow rules about how much leverage they can offer, how they handle customer money, and how they disclose risks. An unregulated broker can disappear with your money, offer unlimited leverage, or manipulate prices in their favour. Before opening an account, check whether your broker is regulated and whether you can verify that status with the regulator's website.

Most brokers offer a demo account where you can practice trading with fake money. This is useful for learning how the platform works and testing a trading strategy without risking real money. Demo accounts show you how orders execute and how leverage works, but they do not show you how it feels to lose real money, which changes how traders make decisions.

Common ways traders lose money

The most common reason traders lose money is using too much leverage on positions they do not fully understand. A trader opens a large position, the market moves 1 or 2 percent against them, and their account is wiped out. This happens because they did not use a stop-loss or did not size their position correctly for the risk they were taking.

Trading during high-volatility events — like central bank announcements or major economic data releases — can cause prices to gap past your stop-loss, meaning your order executes at a much worse price than you expected. This is called slippage. On a normal day, slippage is small. During volatile events, it can be large enough to turn a small loss into a large one.

Overconfidence after a few winning trades is another trap. A trader makes money on three trades in a row and then increases position size or takes bigger risks, assuming the winning streak will continue. Markets do not work that way. Even professional traders have losing streaks, and a single large loss can erase weeks of small gains.

Frequently Asked Questions

Can I make money trading forex?

Some traders do, but most retail traders lose money. The forex market is competitive, prices move fast, and leverage makes it easy to lose more than you deposited. If you trade, start small, use a stop-loss on every trade, and never risk more than you can afford to lose.

What is the minimum amount I need to start trading?

Most brokers allow you to open an account with $100 to $500, but this amount is too small to trade safely. With leverage, you can control larger positions, but a single bad trade can wipe out a small account instantly. Many traders recommend starting with at least $2,000 to $5,000 so you have room to make mistakes while learning.

Is forex trading the same as gambling?

Forex trading involves risk and uncertainty, like gambling, but it is not gambling in the legal sense. Gambling is betting on a random outcome. Forex traders analyze economic data, charts, and market conditions to make decisions. That said, many retail traders trade without a plan and lose money quickly, which resembles gambling more than investing.

Why do some traders use robots or automated systems?

Automated trading systems execute trades based on rules you set in advance — for example, "buy when the price crosses above this line." The appeal is that robots do not get emotional or tired. The risk is that a robot can execute many losing trades in a row if market conditions change and the rules no longer work. Robots are tools, not replacements for understanding how markets work.

What happens if my broker goes out of business?

If your broker is regulated in the United States, your account is protected up to a certain amount by the Securities Investor Protection Corporation (SIPC), though forex accounts have lower protection limits than stock accounts. If your broker is unregulated or based outside the US, you have little recourse. This is why choosing a regulated broker matters.
