What happens when you trade currencies on forex

Forex trading means buying one currency while selling another at the same time. When you place a trade, you are betting that the price of one currency will move relative to another. For example, if you buy euros and sell US dollars, you profit when the euro strengthens against the dollar — and lose money when it weakens. The price moves constantly during market hours, and you can close the trade at any point to lock in a gain or loss.

The forex market operates 24 hours a day, five days a week, across major financial centers in Tokyo, London, and New York. Unlike a stock exchange with a single physical location, forex trades happen over the counter — meaning banks, brokers, and traders execute deals directly with each other through electronic networks. This decentralized structure means there is no single "opening bell" and no single price; different brokers may quote slightly different rates at the same moment.

Most individual traders do not actually take possession of the currency they buy. Instead, they use a broker to execute the trade and typically close it within hours, days, or weeks. The broker holds the position on your behalf and charges a fee or spread — the difference between the buying price and selling price — for this service.

Key Takeaways

  • Forex trades involve buying one currency and selling another simultaneously, with profit or loss depending on how the exchange rate moves between them.
  • The forex market operates continuously across global financial centers and has no central exchange, so prices are quoted by individual brokers and banks.
  • Most retail traders use leverage provided by brokers, meaning they control large positions with a small deposit, which amplifies both gains and losses.
  • Currency prices move based on interest rates, economic data, geopolitical events, and the flow of money between countries.
  • Brokers earn money through spreads or commissions, and traders can trade major pairs like EUR/USD or exotic pairs involving smaller economies.

How leverage works and why it matters

Leverage is a loan from your broker that 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 a $1,000 deposit. This magnifies your potential profit — but it also magnifies your loss. A 2% move in the currency pair could wipe out your entire $1,000 deposit or double it, depending on the direction.

Brokers set leverage limits based on regulation and their own risk tolerance. In the United States, the maximum leverage for retail traders is 50:1 on major currency pairs. In other countries, leverage can be higher or lower. The higher the leverage, the smaller the price movement needed to trigger a margin call — a demand from your broker to deposit more money or close positions to cover losses.

Leverage is not free. Your broker charges interest on the borrowed amount, and that cost compounds daily. If you hold a leveraged position overnight, you pay a financing fee. Over weeks or months, these fees can eat into your returns significantly.

What moves currency prices

Currency values rise and fall based on supply and demand, which is driven by several factors. Interest rates are the biggest influence: when a central bank raises rates, investors want to hold that currency to earn higher returns, so demand increases and the currency strengthens. When rates fall, the opposite happens.

Economic data also moves prices. Reports on employment, inflation, GDP growth, and trade balances tell investors whether an economy is strengthening or weakening. A stronger economy usually means a stronger currency. Traders watch these reports closely and position themselves before the data is released, so prices can swing sharply in the minutes after an announcement.

Geopolitical events — wars, elections, trade disputes, sanctions — create uncertainty and shift money flows between countries. Safe-haven currencies like the US dollar and Swiss franc tend to strengthen during crises, while riskier currencies weaken. Central bank statements and policy decisions also move prices, sometimes dramatically, because they signal future interest rate changes.

The difference between major, minor, and exotic currency pairs

Currency pairs are divided into categories based on trading volume and liquidity. Major pairs include the US dollar paired with other large economies: EUR/USD (euro and dollar), GBP/USD (British pound and dollar), USD/JPY (dollar and yen), and USD/CHF (dollar and Swiss franc). These pairs trade in enormous volume, spreads are tight, and prices move smoothly.

Minor pairs (also called cross pairs) do not include the US dollar. Examples are EUR/GBP (euro and pound) or AUD/NZD (Australian and New Zealand dollars). They trade less volume than majors, spreads are wider, and prices can be more volatile. Exotic pairs involve a major currency paired with a smaller economy — for example, EUR/TRY (euro and Turkish lira) or USD/MXN (dollar and Mexican peso). Exotic pairs have the widest spreads, lowest liquidity, and highest volatility, making them riskier for most traders.

Most beginning traders start with major pairs because the tighter spreads and higher liquidity mean lower costs and more predictable price movement. As you gain experience, you may explore minors and exotics, but the wider spreads and lower liquidity mean you need larger price moves to profit.

How brokers make money and what you pay

Forex brokers earn revenue in two main ways: spreads and commissions. A spread is the difference between the bid price (what you receive if you sell) and the ask price (what you pay if you buy). On EUR/USD, the spread might be 1 pip (0.0001) on a major broker, meaning you start 1 pip in the hole the moment you open a trade. On exotic pairs, spreads can be 10 pips or wider.

Some brokers charge a commission per trade instead of or in addition to spreads. A commission might be $5 to $10 per 100,000 units traded. Commission-based brokers often advertise tighter spreads, but the total cost depends on your trade size and how frequently you trade. A trader making 20 trades per day pays commissions that add up quickly.

Brokers also earn money on overnight financing fees if you hold positions past the daily settlement time. These fees are based on the interest rate differential between the two currencies and are charged or credited to your account daily. On some pairs, you may earn interest; on others, you pay it.

The role of pips and lot sizes in calculating profit and loss

A pip is the smallest price movement in a currency pair. For most pairs, one pip equals 0.0001 (one ten-thousandth). For pairs involving the Japanese yen, one pip is 0.01 because the yen trades at a much lower absolute value. If EUR/USD moves from 1.0850 to 1.0851, that is a one-pip move.

A lot is the standard unit size for a forex trade. One standard lot equals 100,000 units of the base currency. A mini lot is 10,000 units, and a micro lot is 1,000 units. The lot size you choose determines how much money each pip movement is worth. On a standard lot of EUR/USD, one pip is worth $10. On a mini lot, one pip is worth $1. On a micro lot, one pip is worth $0.10.

If you buy one standard lot of EUR/USD at 1.0850 and sell at 1.0860, you have moved 10 pips and made $100 profit (before spreads and fees). If you use 50:1 leverage, you only needed $2,000 in your account to open that position. The same 10-pip move represents a 5% return on your deposit — but a 10-pip move against you would be a 5% loss.

How to read a forex quote and place a trade

A forex quote shows two prices: the bid and the ask. If you see EUR/USD quoted as 1.0850 / 1.0852, the bid (1.0850) is what you receive if you sell euros, and the ask (1.0852) is what you pay if you buy euros. The 2-pip difference is the spread. The first currency in the pair (the euro) is the base currency, and the second (the dollar) is the quote currency.

To place a trade, you log into your broker's platform, select the currency pair, choose your lot size, and decide whether to buy (go long) or sell (go short). If you buy, you are betting the base currency will strengthen. If you sell, you are betting it will weaken. You can set a stop-loss order (a price at which the trade closes automatically to limit losses) and a take-profit order (a price at which it closes to lock in gains). Most brokers require you to set a stop-loss before opening a leveraged position.

Once you submit the order, the broker executes it at the current market price or the price you specified. Your position is now open, and you can monitor it in real time. You can close it at any time by clicking a button, or let it run until your stop-loss or take-profit is hit.

Why most retail traders lose money

Forex trading is not a path to quick wealth. Studies show that the majority of retail traders lose money, especially in the first year. The reasons are consistent: overleveraging (using too much borrowed money), poor risk management (not setting stop-losses or setting them too wide), emotional trading (chasing losses or holding winners too long), and underestimating the cost of spreads and fees.

Leverage is the biggest culprit. A trader with a $1,000 account using 50:1 leverage can wipe out their entire deposit with a 2% move against them. Even if they are right 60% of the time, the losses on the 40% of losing trades can exceed the gains on winners because the losses are larger. This is called negative expectancy, and it is why position sizing and risk management matter more than being right.

Spreads and overnight fees also compound losses. On a $1,000 account making 20 trades per month with a 2-pip spread on each trade, you pay $40 in spreads alone. If you hold positions overnight, financing fees add another $10 to $20 per month. These costs are invisible but real, and they work against you every single day.

Frequently Asked Questions

Can I make money trading forex with a small account?

Yes, but the odds are against you. A $1,000 account can generate profits, but the percentage gains needed to cover spreads and fees are high, and one bad trade can wipe you out. Most successful traders start with larger accounts ($5,000 to $10,000 or more) so they can risk a small percentage per trade and survive losing streaks.

What is the difference between forex and stocks?

Stocks represent ownership in a company; forex is a bet on currency price movement. Stocks trade during market hours on exchanges; forex trades 24/5 over the counter. Stocks typically use lower leverage (2:1 to 4:1); forex brokers offer much higher leverage (up to 50:1 in the US). Stocks have lower spreads and commissions; forex spreads vary widely by pair and broker.

Do I need to predict the direction of the economy to trade forex?

Not necessarily. You can trade based on technical analysis (price patterns and indicators), economic data releases, or central bank statements without having a view on the long-term economy. Many traders focus on short-term price movement and ignore the bigger picture. However, understanding what drives currency prices helps you avoid trading against major economic trends.

What happens if my broker goes out of business?

In the United States, forex brokers are regulated by the Commodity Futures Trading Commission (CFTC) and must segregate customer funds in separate bank accounts. If a broker fails, your money is protected up to the amount held in segregated accounts. In other countries, protections vary. Always check whether your broker is regulated and what protections apply in your jurisdiction.

Can I trade forex on my phone?

Yes. Most brokers offer mobile apps that let you view charts, place trades, and manage positions from your phone. Mobile trading is convenient but also dangerous because it makes impulsive trading easier. Many traders make worse decisions on their phones than they do at a computer, so use mobile apps for monitoring, not for making big decisions.
