Forex Trading Guide

The foreign exchange (forex) market is the largest and most liquid financial market in the world, with over $7.5 trillion in daily trading volume. This guide explains its structure, participants, and how trading works.

The forex market operates 24 hours a day, five days a week, spanning major financial centers across Sydney, Tokyo, London, and New York. Unlike stock exchanges, forex has no central physical location — it is a decentralised global network of banks, brokers, institutions, and individual traders.

Participants range from central banks and commercial banks to hedge funds, multinational corporations, and retail traders. Central banks intervene to stabilise or influence their currency, while corporations hedge cross-border exposure. Retail traders, now the fastest-growing segment, access the market through online brokers offering leverage and real-time execution.

Currencies trade in pairs — buying one currency simultaneously sells another. The exchange rate reflects how much of the quote currency is needed to buy one unit of the base currency. Profit or loss comes from movements in these rates, driven by interest rates, economic data, geopolitical events, and market sentiment.

Major Trading Sessions

The forex day is divided into three main sessions. The Asian session (Tokyo) opens first, followed by the European session (London), which overlaps with the tail end of Asian trading. The North American session (New York) opens as London is at its midpoint. The London–New York overlap, roughly 12:00 to 16:00 GMT, is the most volatile period with the highest liquidity. Each session has distinct characteristics — the Asian session tends to range-bound, London drives trends, and New York often accelerates moves following US economic releases.

Market Participants and Liquidity

Liquidity is deepest when multiple sessions overlap. The interbank market, where the largest banks trade directly with each other, sets the wholesale rates that brokers and ECNs pass to retail traders. Bid–ask spreads are tightest during high-liquidity periods and widen during news events or after-hours trading. Understanding who is in the market and when helps traders choose optimal times for entries and exits.

FAQs

Can I trade forex with a small account?

Yes, many brokers allow micro-lot trading and offer high leverage, enabling accounts as small as $50 to open positions. However, risk management becomes critical at small account sizes.

What drives forex prices most?

Interest rate differentials, economic indicators (GDP, employment, CPI), central bank policy, and geopolitical risk are the primary drivers of medium- to long-term moves.

Is forex trading risky?

Forex trading carries significant risk, especially when using leverage. Most retail traders lose money. Proper education, a trading plan, and strict risk controls are essential.
