What happens when you open a forex trade

Forex trading means buying one currency while selling another at the same time. When you trade EUR/USD, you are buying euros and selling US dollars. The price you see — say 1.0850 — tells you how many dollars you need to spend to buy one euro. If the euro strengthens to 1.0900, that same euro is now worth more dollars, and you can sell it for a profit. If it weakens to 1.0800, you lose money.

You do not need to own the currencies themselves. A forex broker holds the money and executes the trade on your behalf. You deposit cash into a trading account, place an order through the broker's platform, and the broker records the transaction. When you close the trade — by selling the euros back — the broker calculates your gain or loss and adds or subtracts it from your account balance.

The forex market operates 24 hours a day, five days a week, across four major trading sessions: Tokyo, London, New York, and Sydney. This means you can trade at almost any time, though volume and price movement vary by session. Most retail traders work during their local business hours or early morning, when their chosen currency pair is most active.

Key Takeaways

  • Forex trades happen in pairs: you buy one currency and sell another simultaneously, and profit or lose based on the price change between them.
  • You need a brokerage account with a regulated forex broker, initial deposit (often $100 to $2,500 depending on the broker), and trading software to place orders.
  • Leverage lets you control a large position with a small deposit, but it magnifies both gains and losses — a 1 percent move in the market can wipe out your entire account if leverage is high.
  • Most retail traders lose money because they underestimate risk, trade without a plan, and do not use stop-loss orders to limit losses on individual trades.
  • You pay the broker through the spread — the difference between the buy price and sell price — not through commissions or fees in most cases.

Opening a brokerage account and funding it

Start by choosing a regulated forex broker. In the United States, the Commodity Futures Trading Commission (CFTC) and the National Futures Association (NFA) regulate forex brokers. In the European Union, the Financial Conduct Authority (FCA) oversees them. Check the broker's regulatory status on the CFTC or FCA website before you deposit money. Unregulated brokers can refuse to return your funds or manipulate prices against you.

Most brokers require a minimum deposit to open an account. This ranges from $100 to $2,500 depending on the broker and account type. Some brokers offer micro accounts with lower minimums. You will provide your name, address, phone number, and email, and the broker will ask for proof of identity (a driver's license or passport) and proof of address (a recent utility bill or bank statement). This process, called Know Your Customer (KYC), is required by law.

After approval, you fund the account by bank transfer, credit card, or debit card. Bank transfers usually take one to three business days. Credit and debit card deposits are instant but may carry higher fees. Once the money is in your account, you can begin trading immediately.

How to place a trade and set your position size

Log into your broker's trading platform — most brokers use MetaTrader 4 or MetaTrader 5, though some have their own software. Select the currency pair you want to trade (EUR/USD, GBP/USD, USD/JPY, and so on). The platform shows the current bid price (what you receive if you sell) and the ask price (what you pay if you buy). The difference between them is the spread, and it is how the broker makes money.

Decide your position size in lots. One standard lot equals 100,000 units of the base currency. One micro lot equals 1,000 units. If you buy one standard lot of EUR/USD at 1.0850, you are controlling €100,000. At current rates, that requires roughly $108,500 in actual currency — but your broker will let you control that with leverage, meaning you put down only a fraction of that amount (see the leverage section below).

Enter the number of lots you want to buy or sell, then click Buy or Sell. The platform confirms the trade instantly. Your account balance updates to show your deposit minus the margin requirement (the cash the broker holds as collateral). As the price moves, your unrealised profit or loss appears in real time. When you close the trade by clicking Sell (if you bought) or Buy (if you sold), the profit or loss becomes real and is added to or subtracted from your account.

Understanding leverage and margin requirements

Leverage is borrowed money from your broker that lets you control a large position with a small deposit. If your broker offers 50:1 leverage, you can control $50 with a $1 deposit. This magnifies both gains and losses. A 1 percent move in your favour makes you 50 percent on your money. A 1 percent move against you loses you 50 percent.

The margin requirement is the amount of cash your broker holds as collateral. If you trade one standard lot of EUR/USD with 50:1 leverage, the margin requirement is roughly $2,170 (100,000 euros ÷ 50). That cash stays in your account and cannot be withdrawn while the trade is open. If your account balance falls below the margin requirement — because losses have eaten into your deposit — the broker will close your position automatically. This is called a margin call.

High leverage is dangerous for beginners. A 2 percent move against you with 50:1 leverage wipes out your entire account. Most professional traders use 10:1 or lower leverage, and many brokers now restrict retail traders to 30:1 or 50:1 by regulation. Start with the lowest leverage your broker offers and increase it only after you have proven you can trade profitably for at least six months.

Using stop-loss and take-profit orders

A stop-loss order automatically closes your trade at a price you set in advance, limiting your loss if the market moves against you. If you buy EUR/USD at 1.0850 and set a stop-loss at 1.0800, the broker will sell your position automatically if the price drops to 1.0800. You lose 50 pips (price increments), but you do not lose more than that.

A take-profit order automatically closes your trade at a profit target you set in advance. If you set take-profit at 1.0900, the broker sells when the price reaches 1.0900, locking in your gain. This prevents you from watching a winning trade turn into a loss because you held too long hoping for more profit.

Always place a stop-loss before you enter a trade. Traders who skip this step often hold losing positions too long, hoping the market will reverse, and end up with catastrophic losses. Your stop-loss should be close enough to your entry price that the loss is small (usually 1 to 2 percent of your account per trade) but far enough away that normal price fluctuation does not trigger it immediately.

How spreads, swaps, and other costs work

The spread is the difference between the bid and ask price. If EUR/USD is bid at 1.0849 and ask at 1.0851, the spread is 2 pips. When you buy at 1.0851 and immediately sell at 1.0849, you lose 2 pips to the spread. Spreads vary by currency pair and broker. Major pairs like EUR/USD and GBP/USD have tight spreads (1 to 3 pips). Exotic pairs like USD/ZAR have wide spreads (10 to 50 pips or more).

A swap is an overnight interest charge or credit. If you hold a position open past 5 p.m. New York time, the broker charges you (or credits you) based on the interest rate difference between the two currencies. If you buy EUR/USD and hold it overnight, you may pay a small fee because the euro's interest rate is lower than the dollar's. Swaps are usually small — a few dollars per trade — but they add up if you hold positions for weeks or months.

Most forex brokers do not charge commissions on retail trades. They make money from the spread and the swap. Some brokers offer commission-based accounts with tighter spreads but charge a flat fee per trade (usually $2 to $10 per standard lot). Calculate which model costs less based on your trading frequency and position size.

Common mistakes that lead to losses

The most common mistake is trading without a plan. Before you enter a trade, write down your entry price, stop-loss price, take-profit price, and the reason you are taking the trade. If you cannot explain your trade in one sentence, you do not understand it well enough to risk money on it.

The second mistake is risking too much per trade. If you risk more than 1 to 2 percent of your account on any single trade, one bad trade can wipe you out. If your account is $5,000 and you risk $500 per trade, you need only ten losing trades in a row to lose everything. If you risk $50 per trade, you can lose fifty trades in a row and still have money left.

The third mistake is using too much leverage. Beginners often think leverage is assistance programs. It is not. It is borrowed money that you must repay, and if the market moves against you, the broker will close your position and keep your deposit. Start with 10:1 leverage or lower, and only increase it after you have proven you can trade profitably.

The fourth mistake is trading during low-liquidity hours or exotic currency pairs. If you trade a pair with a wide spread during a slow session, you pay more to enter and exit, cutting into your profits. Stick to major pairs (EUR/USD, GBP/USD, USD/JPY, USD/CHF) during the London and New York sessions, when spreads are tightest and price movement is most predictable.

Frequently Asked Questions

How much money do I need to start forex trading?

Most brokers require a minimum deposit of $100 to $2,500. However, you should start with at least $1,000 to $5,000 so that a single losing trade does not wipe out your account. If you risk 1 to 2 percent per trade, a $1,000 account means risking $10 to $20 per trade — small enough to survive a string of losses while you learn.

Can I make money trading forex part-time?

Yes, but it requires discipline and a written plan. Most part-time traders trade during their local morning or evening, focusing on one or two currency pairs. The key is consistency: trade the same strategy, same position size, and same risk level every day. Traders who jump between strategies or change their position size based on emotion usually lose money.

What is the difference between a demo account and a real account?

A demo account uses fake money and lets you practice trading without risk. Most brokers offer free demo accounts for 30 days. Use it to learn the platform, test your strategy, and build confidence. However, demo trading feels different from real trading because there is no emotional pressure. Open a real account with a small deposit after you have been profitable on the demo for at least two weeks.

What happens if my broker goes out of business?

Regulated brokers must segregate client funds — meaning your deposit is held in a separate bank account and cannot be used for the broker's business expenses. If the broker fails, your money is returned to you. Unregulated brokers have no such requirement, so your money can disappear. Always check that your broker is regulated by the CFTC (US), FCA (UK), or your country's financial regulator before you deposit.

How long does it take to become a profitable forex trader?

Most traders take six months to two years to become consistently profitable. The first three months are usually a loss as you learn the platform and test strategies. The next three to nine months involve small profits and losses as you refine your approach. After one to two years of consistent trading, you will know whether forex trading is right for you. If you are not profitable after two years, consider whether the time and money are worth continuing.
