Forex in one paragraph
Forex is short for foreign exchange. It is the global market where currencies are exchanged against each other. Every time a company in Lagos pays a supplier in China, or a tourist from Karachi changes rupees for dollars, a foreign exchange transaction takes place. Retail forex trading is a different thing: an individual opens an account with a broker and speculates on whether one currency will gain or lose value against another.
You never carry foreign banknotes in this kind of trading. You open a position on a screen, and when you close it the difference between the opening and closing price is added to or taken from your balance. That difference is your profit or your loss.
Currency pairs: what you actually trade
Currencies are always traded in pairs, for example EUR/USD. The first currency is the base and the second is the quote. The price tells you how many units of the quote currency one unit of the base currency costs. If EUR/USD shows 1.1000 (an example number), one euro costs 1.10 US dollars.
- If you buy EUR/USD, you expect the euro to get stronger against the dollar.
- If you sell EUR/USD, you expect the euro to get weaker against the dollar.
Pairs fall into groups. Majors include the dollar and another large currency, such as EUR/USD or USD/JPY. Minors are pairs without the dollar, such as EUR/GBP. Exotics combine a major with a smaller currency, and they usually have wider spreads and bigger price jumps. Beginners normally start with one major pair. Our guide to EUR/USD and the main currency pairs goes further.
How a trade works, step by step
Here is a simple worked example. All numbers are made up to show the arithmetic and are not a forecast.
- You decide to buy EUR/USD at 1.1000 with a size of 0.10 lot (10,000 units of the base currency).
- The price rises to 1.1050. The move is 50 pips.
- For a 0.10 lot on this pair, one pip is worth about 1 US dollar, so the gain is about 50 US dollars before costs.
- If the price had fallen to 1.0950 instead, you would have lost about 50 US dollars.
- You close the position, and the result is added to or removed from your balance.
Notice that a loss of the same size is just as likely as the gain. Pips and lots are explained in detail in lots, pips and leverage.
Who is on the other side of the market
The forex market is decentralised. There is no single exchange building. Banks, funds, companies, central banks and brokers trade with each other electronically, and the market is open around the clock from Monday to Friday, because business hours start in Asia, move to Europe and end in North America. Daily turnover is very large, which is why major pairs are easy to buy and sell at any moment, although prices can still jump on news.
As a retail trader you do not reach this interbank market directly. You trade through a broker, which shows you a price and takes the other side of your order or passes it on. Most retail forex trading is done on CFDs (contracts for difference), which means you speculate on the price without owning the currency. A CFD is a contract between you and the broker. This is why choosing a trustworthy broker matters, and we explain how in how to choose a forex broker.
How brokers earn money, and what you pay
A broker earns from the spread (the small gap between the buy and sell price), sometimes from a commission per trade, and from swap fees for positions held overnight. These costs are paid whether you win or lose. A cost of a few pips sounds small, but if you trade often it adds up. Read spread, commission and swap before you open a real account.
Leverage makes everything bigger
Leverage lets you control a position larger than your deposit. With 1:100 leverage, a 100 dollar deposit can control a position worth up to 10,000 dollars. That sounds attractive, but leverage multiplies losses in the same way as gains. A small move against you can wipe out the money in your account. Many beginners lose their first deposit within weeks because they use too much leverage on a single trade.
Who forex trading may suit, and who should skip it
Forex may suit you if you can set aside money you will not need for rent, food or school fees, if you are willing to spend months learning, and if you can accept losses calmly. It does not suit anyone who is borrowing to trade, who needs the money back soon, or who hopes to replace a salary quickly. Be sceptical of anyone who promises a daily income, sells signals with guaranteed results or asks you to deposit into a personal account.
It is also your responsibility to check whether trading with a particular broker is legal where you live. Rules differ by country, and several regulators have published warnings about unlicensed brokers. Brokers that are named in such warnings may still operate, but you may have little or no local protection.
A safe way to start
- Read the basics: pairs, pips, lots, leverage, spread and risk.
- Open a free demo account and practise for at least several weeks. Treat the virtual money as real.
- Write a simple trading plan: which pair, which times, how much you risk per trade.
- If you move to a real account, deposit a small amount that you can afford to lose entirely.
- Keep a journal of every trade and review it every week.

Common myths to drop early
"Forex is a quick way to get rich." Marketing images of luxury cars and beaches are made to sell courses and signals. A realistic goal for a beginner in the first year is to learn the process and keep losses small, not to earn a salary.
"A trading robot will do it for me." Automated systems exist, but robots sold with promises of steady monthly returns are one of the most common scams. A robot still trades on the same market with the same risks, and a system that worked last year can fail this year.
"I can start with 10 dollars and turn it into 10,000." To do that, you would need a very large and very lucky win. Small accounts encourage heavy leverage, and heavy leverage encourages quick losses. A small account is useful for learning how the platform behaves, not for making a living.
"Technical analysis or news always predicts the market." Chart patterns and economic data help you to plan a trade and to find a logical stop-loss. They do not remove uncertainty. Every trade is a probability, and a good plan can still lose.
What the numbers can look like in a simple case
Imagine you test a plan on a demo account over 20 trades. You risk 10 virtual dollars on each trade. You win 8 trades with an average gain of 15 dollars and lose 12 trades with an average loss of 10 dollars. Gains: 8 x 15 = 120. Losses: 12 x 10 = 120. The result before costs is zero, and after spreads it is negative. This invented example shows that a win rate below half can break even only if your winners are larger than your losers, and that costs must be included before you judge any plan. The tools to measure this are your trade journal and the arithmetic in risk management.

Risk warning
Forex and CFDs are complex products with a high risk of losing money quickly because of leverage. Many retail clients lose money, and brokers are required in many countries to publish the percentage of losing accounts on their own risk pages. Trade only with money you can afford to lose entirely. You must be 18 or older. Auron FX is an independent guide, not a broker, and this article is education, not personal investment advice.
