Introduction to the Forex Markets: A Beginner's Guide
Forex — short for foreign exchange — is where the world’s currencies are bought and sold, and it is the largest financial market on the planet. You have almost certainly participated in it without noticing: every time you travel or shop online in another currency, the exchange rate behind that transaction is set in the forex market. This guide is a plain-language starting point: what the market is, how currency pairs work, who trades it, and where automated trading fits in.
What Is the Forex Market?
The forex market is a global, decentralised marketplace where currencies are traded against each other. Unlike a stock exchange, which operates from a single building at set hours, forex has no central location: trading runs through a global network of banks, brokers, and electronic platforms, open around the clock from Monday morning in Sydney to Friday evening in New York — roughly 24 hours a day, five days a week.
By trading volume, forex is the world's largest and most liquid financial market. The Bank for International Settlements surveys it every three years, and its most recent Triennial Central Bank Survey put global over-the-counter turnover at $9.6 trillion per day in April 2025. Liquidity is what makes the market attractive: enormous daily turnover means positions can generally be opened and closed quickly, with tight spreads between what buyers pay and sellers receive.
How Currency Pairs Work
Currencies are always traded in pairs, because every trade is an exchange: you buy one currency and sell another at the same moment. The first currency in the pair is the base, the second is the quote, and the price tells you how much of the quote currency one unit of the base costs. In EUR/USD, for example, the euro is the base and the US dollar the quote: a price of 1.10 means one euro buys 1.10 US dollars. If the price rises, the base is getting stronger relative to the quote; if it falls, the opposite.
The most traded pairs, known as the majors, all involve the US dollar — EUR/USD, GBP/USD, USD/JPY, USD/CHF, and the commodity-linked AUD/USD, USD/CAD, and NZD/USD. Pairs without the dollar, like EUR/GBP, are called crosses, and pairs involving a smaller or emerging-market currency are exotics. Two further concepts matter from day one: the spread is the difference between the bid (the price you sell at) and the ask (the price you buy at), which is how brokers charge for the trade; and the pip is the standard unit of price movement, usually the fourth decimal place, which is how profits and losses are measured.
Who Trades Forex (Retail, Institutional, Central Banks)
Different layers of the market trade for very different reasons. At the top sit central banks — the Bank of England, the Federal Reserve, the European Central Bank and others — which trade to manage monetary policy, influence interest rates, and steady their currencies, often in volumes large enough to move the market on announcement days. Below them, institutional participants — commercial banks, hedge funds, asset managers, and multinational corporations — trade to execute client orders, hedge currency exposure, or speculate on direction.
Retail traders — individuals trading through brokers, typically on margin via CFDs or similar instruments — represent a small fraction of overall volume. Retail traders do not move the market; they trade within it, using the same prices that institutional volume sets.
Manual Trading vs Automated Trading
There are two ways to place trades, and most beginners start by imagining manual trading: sitting at a chart, analysing price movement, deciding to buy or sell, and executing each trade yourself. Manual trading is flexible — you can respond instantly to news and changing conditions — but it carries a heavy emotional load. Fear and greed are the two most reliable ways to destroy an account, which is why discipline is repeatedly cited as the hardest skill in the field.
Automated trading removes the emotional bottleneck by encoding a strategy into rules that run without you. An Expert Advisor (EA) is a program that analyses the market and opens, manages, and closes trades automatically according to those rules — which can be backtested against years of historical data before a single pound is risked. Our beginner's guide to what an Expert Advisor is covers how they work in more depth. Automation does not remove risk, but it removes the impulsive decisions that amplify risk. If the idea of running rules appeals to you, our best expert advisors page shows the EAs we have actually vetted.
And if you want convenience without managing a robot yourself, copy trading lets you mirror the trades of experienced traders automatically.
Getting Started Safely
The gap between understanding forex and trading it safely is where most beginners lose money. The sequence that protects you is simple:
Learn on a demo account — every legitimate broker offers one, with virtual money and real prices, and it is the only sensible place to test strategies and your own reaction to losses.
Treat the market’s numbers honestly — the majority of retail traders lose money; trading on margin amplifies both gains and losses; and the resolution of losses is never “it will come back”, it is a closed account.
Only risk money you can afford to lose outright.
Finally, choose your broker deliberately rather than on the basis of a bonus offer or a celebrity advert. Regulation is the first filter: a broker authorised by a serious authority such as ASIC, the FCA or CySEC must segregate client money and meet conduct standards that unregulated operators do not. What differs between them is compensation cover if the broker fails — our comparison of ASIC, FCA and CySEC sets out who protects what. Spreads, execution speed, platform reliability, and withdrawal behaviour come next. Our best brokers page compares vetted brokers on exactly those criteria, based on our own testing.
FAQs
How much money do I need to start trading forex?
You can open a demo account with nothing, and many brokers accept live accounts from around £50 to £100. But the minimum to open is not the right amount to start with: begin with an amount you can afford to lose, practise until you have a consistent edge on demo, and only then risk capital.
What is the best time of day to trade forex?
The most active — and usually the most liquid — hours are when the London and New York sessions overlap: early afternoon in London, morning in New York, a window of roughly four hours. These hours typically offer the tightest spreads and the clearest price movement. Asian-session hours are quieter, with wider spreads and thinner liquidity.
Can beginners trade forex with an Expert Advisor?
Yes, and automation is often a sensible starting point because it enforces discipline — but only after you understand the basics well enough to evaluate the EA honestly. Never buy an EA on the strength of its marketing page: check for a verified track record, a transparent strategy explanation, and honest risk disclosure first. Our free EA Red Flag Checklist turns those checks into a list you can work through, and how we test Expert Advisors sets out the standard we hold every reviewed product to.
