Forex — Trading Currencies

The biggest market in the world. Why retail traders mostly lose money.

8 min read Intermediate

"The foreign exchange market trades $7.5 trillion per day. Banks, central banks, and multinationals use it constantly. Retail traders also use it. Roughly 70-80% of retail forex traders lose money. This chapter explains why."

For educational purposes only. Nothing in this chapter is financial advice. All figures are illustrative examples. Tax rules, account types, contribution limits, and regulations differ by country and change over time. Always verify current rules with official government sources or a qualified financial adviser before making any investment decisions.

What Is the Forex Market?

The foreign exchange market is where currencies are bought and sold. It is the largest financial market in the world — $7.5 trillion traded per day. To put that in perspective: the entire New York Stock Exchange handles about $25 billion per day. Forex is 300 times larger.

Every time a company imports goods from another country, a tourist exchanges currency at an airport, or a central bank intervenes to stabilise its currency — that is the forex market. It operates 24 hours a day, 5 days a week, across time zones from Sydney to London to New York.

Currency Pairs and Pips

Currencies always trade in pairs. You are always buying one currency by selling another. EUR/USD = Euro vs US Dollar. GBP/USD = British Pound vs US Dollar. The first currency is the "base" — the second is the "quote".

A pip (percentage in point) is the smallest standard price move — typically the fourth decimal place. EUR/USD moving from 1.0850 to 1.0851 is one pip. For a standard 100,000 unit trade, one pip = approximately $10. For a £1,000 retail trade with 30x leverage, one pip = £3 — which sounds small until you see a 50-pip move against you in 10 minutes.

Why Retail Forex Traders Lose Money

The FCA requires UK brokers to disclose what percentage of retail clients lose money trading CFDs (which is how most retail forex is accessed). The numbers are stark:

Retail CFD clients who lose money (broker-disclosed, required by FCA)

IG Group

71%

CMC Markets

75%

Spreadex

73%

City Index

74%

These figures are legally required to appear in broker advertising. They represent real account outcomes, not simulations.

The reasons are structural. Retail traders face the spread (the difference between buy and sell price) on every trade. They pay overnight financing costs if they hold positions. They use leverage, which amplifies losses as well as gains. And they are competing against algorithms, institutional traders, and people who do this full-time with decades of experience.

Who Should Actually Trade Forex?

Forex has legitimate uses. If your income is in one currency and your expenses in another — perhaps you work abroad, invest in US stocks from the UK, or run a business with international customers — managing currency exposure is genuinely useful.

For speculative retail trading — buying and selling currency pairs to profit from short-term moves — the evidence is overwhelmingly negative. The 70-80% loss rate is not a scare statistic. It is a legally required disclosure that major brokers are obliged to publish.

If you are considering forex trading, ask yourself:

Do I have an information or analytical edge over institutional participants? (Almost certainly no.)
Am I prepared to lose my entire investment? (Because it happens often.)
Is there a simpler way to achieve my goal? (Usually yes — currency-hedged ETFs for international investing, for example.)

Questions People Actually Ask

Can I make money trading forex?

Some people do. The 25-30% who are profitable exist. But they are typically professional traders with years of experience, significant capital, sophisticated tools, and a genuine informational or systematic edge. For the majority of retail participants who start with a few hundred or thousand pounds, the historical odds are heavily against consistent profitability after costs.

What is a spread in forex?

The spread is the difference between the price you can buy a currency pair (ask) and the price you can sell it (bid). If EUR/USD has a bid of 1.0849 and an ask of 1.0851, the spread is 2 pips. You are immediately 2 pips in the negative when you open a trade — you need the price to move at least 2 pips in your favour just to break even. Spreads widen significantly outside peak trading hours.

What is leverage in forex?

Leverage allows you to control a large position with a small deposit. With 30:1 leverage (the FCA maximum for major currency pairs), £1,000 controls a £30,000 position. A 1% move in your favour = £300 profit on your £1,000. A 1% move against you = £300 loss — 30% of your capital gone in one move. Leverage amplifies both directions equally and without mercy.

What is a pip?

A pip (percentage in point) is typically the fourth decimal place in a currency pair. EUR/USD moving from 1.0850 to 1.0860 = 10 pips. For a standard lot (100,000 units), 1 pip = approximately $10. For a mini lot (10,000 units), 1 pip = approximately $1.

Is forex trading gambling?

This is genuinely debated. For retail traders using high leverage to speculate on short-term price moves with no edge, the mathematical structure is similar to a negative expectancy game. For institutional participants with systematic strategies and genuine information advantages, it is a legitimate business. The distinction is the edge — or lack of one.

Key Takeaways

Forex is the world's largest market at $7.5 trillion/day — dominated by banks, central banks, and institutions, not retail traders.
Currencies trade in pairs. You always buy one currency by selling another. Moves are measured in pips.
FCA-regulated brokers are required to disclose loss rates: 70-80% of retail CFD clients lose money. This is a legal obligation, not a warning label.
Leverage amplifies losses as fast as gains — 30:1 means a 3.3% move wipes your entire position.
Forex speculation is not recommended for most retail investors. Currency exposure for genuine international investment needs is different and legitimate.
