This article is an instrument map: it covers only the big picture and the core concepts. To dig deeper, go straight to Chapter 23 · Forex Trading in Practice — that is the main course on this topic.
The foreign exchange (FX / Forex) market is the world's largest, most liquid, and longest-trading financial market: no central exchange, no price limits, running 24 hours a day from Monday to Friday. But large scale does not mean easy money — this is the institutions' home ground, and retail traders who enter with high leverage mostly end up eaten alive by time, the spread, and rogue platforms. This article keeps only the map; all the depth lives in Chapter 23.
1. Market Panorama at a Glance
| Dimension | Quick view |
|---|---|
| Market size | Average daily turnover about USD 7.5 trillion (2022 BIS survey; defer to the latest survey); over-the-counter (OTC), no central exchange |
| Trading centers | London (~40% share) > New York > Singapore > Hong Kong > Tokyo; banks dominate (~45%), retail share is under 10% |
| Trading sessions | 24-hour relay from Monday to Friday: Sydney (~06:00–14:00, thin) → Tokyo (~08:00–15:30, yen active) → London (~15:30–00:30, volatility expands) → New York (~20:00–05:00); the London-New York overlap (~20:00–00:30, Beijing time) is the most volatile window of the day |
| Major pair | Characteristics at a glance |
|---|---|
| EUR/USD | The largest share of global turnover (~22%), the narrowest spread, the only pair recommended for beginners |
| USD/JPY | Dual "safe haven + rate differential" character; heavily influenced by BOJ policy |
| GBP/USD | Volatile with many false breakouts; nicknamed "Cable" |
| USD/CHF | The traditional safe-haven currency, often moving with gold |
| USD/CAD | The "petro currency", highly correlated with oil prices |
| AUD/USD | Tracks iron ore and Chinese demand; rate-sensitive |
| NZD/USD | Tracks dairy products and moves with the AUD |
Sessions reflect daylight saving time (March–October) in Beijing time; in winter everything shifts 1 hour later. Market open/close times follow platform announcements.
2. Five Core Concepts
- Paired quoting: forex always trades in pairs of
Base Currency/Quote Currency(e.g., EUR/USD). You always buy at the Ask and sell at the Bid — the difference is the spread, your first cost. - Pips and pip value: 1 pip is usually the 4th decimal (the 2nd for USD/JPY). 1 standard lot (100,000 base currency) of EUR/USD = USD 10 per pip; USD/JPY is about USD 6.67 per pip and varies with the exchange rate.
- Leverage and the math of blowing up: margin = notional value ÷ leverage. A USD 1,000 account fully invested in 1 lot at 1:100 leverage is wiped out by 100 adverse pips — and 100+ pip days in EUR/USD are routine. Leverage amplifies "speed", not "win rate".
- The US Dollar Index DXY: measures the dollar's overall strength against a basket of major currencies (the euro dominates at ~57.6% weight); it is the "ruler" of gold/oil/non-US assets — full details in Chapter 23, Article 01.
- The price of OTC: with no official exchange, regulation relies on licenses, and licenses can be faked — rogue platforms are the retail trader's biggest non-market risk (see 08 - Pitfalls / 02 - Scam Detection and Chapter 23, Article 03).

Risk Warning
⚠️ Risk Warning
Forex margin trading carries extreme leverage risk and can drive your principal quickly to zero or even into debt (negative balance). Globally, the share of retail forex investors who are consistently profitable is extremely small; fraud risk on unregulated platforms is far higher than in legitimate markets. All figures on this page are teaching-basis (referencing 2022 BIS data and industry common sense); always defer to the latest quotes, regulations, and platform rules.
