What happens when you open a forex trade

When you trade on forex, you are buying one currency and selling another at the same time. For example, you might buy euros and sell US dollars. The price you pay depends on the exchange rate — how much of one currency you need to get another. You place this trade through a forex broker, a company licensed to let you buy and sell currencies.

The trade itself takes seconds. Your broker matches you with a seller (or their own inventory) and the transaction settles. But the currency pair stays open until you close it — meaning you still own the euros and owe the dollars. You close the trade by doing the opposite: selling the euros and buying back the dollars. The difference between what you paid and what you received is your profit or loss.

Most forex trades are not about actually receiving physical currency. Instead, you are betting on whether the exchange rate will move in your favor. If you bought euros at 1.10 dollars per euro and the rate rises to 1.12, you can close the trade and pocket the difference.

Key Takeaways

  • You need a forex broker account to trade; the broker provides the platform and holds your money.
  • Every forex trade involves two currencies at once — you buy one and sell the other in a single transaction.
  • Trades stay open until you close them by doing the reverse transaction, and your profit or loss is the difference in exchange rates.
  • Leverage lets you control larger trades with less money upfront, but it also magnifies losses if the trade moves against you.
  • Most retail forex trades are settled in cash rather than physical currency delivery.

Opening a forex broker account

Before you can trade, you need an account with a forex broker. The broker is the intermediary — they provide the trading platform, hold your money, and execute your trades. Choose a broker that is regulated by a financial authority in your country. In the United States, the Commodity Futures Trading Commission (CFTC) and the National Futures Association (NFA) oversee forex brokers. In the UK, the Financial Conduct Authority (FCA) does. Regulation does not may provide you will not lose money, but it means the broker must follow rules about how they handle your account.

To open an account, you will provide your name, address, and identification. The broker will ask about your income, employment, and trading experience. They may also ask why you want to trade forex. This is called know-your-customer (KYC) verification and is required by law. Once approved, you fund the account by transferring money from your bank. Most brokers accept wire transfers, credit cards, or bank transfers. The money sits in your account as your trading capital — the amount you can use to open trades.

Some brokers offer a demo account first, which lets you practice trading with fake money. This is useful if you have never traded before, because you can learn how the platform works without risking real money.

Understanding currency pairs and how prices move

Forex trades always involve two currencies written as a pair, like EUR/USD (euros and US dollars). The first currency is the base currency and the second is the quote currency. The price tells you how much of the quote currency you need to buy one unit of the base currency. If EUR/USD is trading at 1.10, one euro costs 1.10 dollars.

The price moves constantly during trading hours because people are always buying and selling. When more people want to buy euros than sell them, the price goes up. When more people want to sell, it goes down. You profit when the price moves in the direction you predicted. If you bought EUR/USD at 1.10 and it rises to 1.12, you have made 0.02 per euro. On a trade of 100,000 euros, that is a 2,000 dollar profit.

Prices are quoted with four decimal places, called pips. A pip is the smallest price move. If EUR/USD moves from 1.1050 to 1.1051, that is one pip. Most retail traders track profit and loss in pips because it is easier than tracking dollars.

Placing your first trade

On your broker's platform, you will see a list of currency pairs. Select the pair you want to trade. Then you decide whether you think the price will go up or down. If you think it will go up, you place a buy order (also called going long). If you think it will go down, you place a sell order (also called going short).

Next, you choose how much to trade. This is measured in lots. One standard lot is 100,000 units of the base currency. A mini lot is 10,000 units and a micro lot is 1,000 units. If you are new to trading, start with micro lots or mini lots so a small price move does not wipe out your account.

You also set a stop loss — an automatic order that closes your trade if the price moves too far against you. For example, if you buy EUR/USD at 1.10, you might set a stop loss at 1.09. If the price falls to 1.09, your trade closes automatically and you lose 0.01 per euro. Without a stop loss, you could lose far more if the price keeps falling.

Once you confirm the order, it is sent to the market. Your broker matches it with a seller and the trade opens. You now own the base currency and owe the quote currency.

How leverage works and why it is risky

Most forex brokers offer leverage, which lets you control a large trade with a small amount of money. For example, with 50:1 leverage, you can control 50 dollars of currency for every 1 dollar you put up. This means you only need 2,000 dollars to open a 100,000-unit trade.

Leverage magnifies both gains and losses. If the price moves 1 percent in your favor, you make 1 percent on your actual money — not on the total trade size. But if the price moves 1 percent against you, you lose 1 percent of your money. On a 2,000 dollar deposit, a 1 percent loss is 20 dollars. On a 5 percent loss, you lose 100 dollars. On a 10 percent loss, your account is wiped out.

Leverage is why many new traders lose money quickly. They use too much leverage and a small price move against them closes their account. Most experienced traders use low leverage — 5:1 or 10:1 — or no leverage at all. Regulators in many countries have capped retail leverage at 50:1 or lower to protect traders.

Closing a trade and understanding your profit or loss

You close a trade by doing the opposite of what you did to open it. If you bought EUR/USD, you sell it to close. If you sold it, you buy it back to close. When you close, your broker calculates the difference between your entry price and your exit price. That difference, multiplied by the number of units you traded, is your profit or loss.

For example: you bought 10,000 euros (a mini lot) at 1.10 dollars per euro. You spent 11,000 dollars. The price rises to 1.12 and you sell. You receive 11,200 dollars. Your profit is 200 dollars. If the price had fallen to 1.08 instead, you would have received 10,800 dollars and lost 200 dollars.

Your broker deducts the loss from your account or adds the profit. You can then use that money to open new trades or withdraw it. If you close a trade at a loss, that loss is real — you cannot get the money back by holding the trade longer.

Common mistakes new forex traders make

The most common mistake is using too much leverage on the first trades. New traders see that they can control 100,000 dollars with 2,000 dollars and think they will make fast money. Instead, a small price move wipes out their account. Start with micro lots and low leverage until you understand how the market moves.

Another mistake is trading without a stop loss. If you do not set one, a trade can lose far more than you planned. The market can move quickly and you might not be watching. A stop loss closes the trade automatically and limits your loss to a known amount.

Many new traders also trade too often. They open and close trades multiple times a day, paying commissions or spreads each time. Over time, these costs add up and eat into profits. It is better to trade less often with a clear plan for each trade.

Finally, new traders often trade without a plan. They see a price move and jump in without thinking about where they will exit or how much they are willing to lose. Before you open any trade, write down your entry price, stop loss, and target price. This keeps you from making emotional decisions.

Frequently Asked Questions

Do I need a lot of money to start forex trading?

No. You can open a forex account with as little as 100 dollars at many brokers. However, with a small account and leverage, a few losing trades can wipe you out quickly. Most traders recommend starting with at least 1,000 to 2,000 dollars so you can trade micro lots and survive a losing streak.

What time of day should I trade forex?

Forex markets are open 24 hours a day, five days a week, but prices move most during the overlap of major trading sessions. The London and New York sessions overlap from 8 a.m. to noon Eastern Time, and that is when most volume and price movement happens. New traders often do better trading during these hours because prices move more predictably.

Can I lose more money than I deposit?

Yes, if you use leverage and the price moves sharply against you. However, many brokers now offer negative balance protection, which means they will not let your account go below zero. Check your broker's policy before you start trading. Even with protection, you can lose your entire deposit.

What is the difference between forex and stocks?

Stocks represent ownership in a company. Forex is currency exchange — you are betting on whether one currency will strengthen or weaken against another. Forex markets are open 24 hours and use much more leverage than stocks. Stocks are usually better for long-term investing, while forex is used for short-term trading.

How much should I risk on each trade?

Most professional traders risk between 1 and 2 percent of their account on each trade. If your account is 2,000 dollars, that means risking 20 to 40 dollars per trade. This way, even if you lose five trades in a row, you still have most of your money left. Never risk more than 5 percent on a single trade.
