The forex market is a global financial system where currencies are exchanged continuously across different time zones. Unlike traditional stock markets, forex operates without a central exchange and remains active for most of the day during the trading week.
Understanding how the forex market works—including trading sessions, liquidity, and market participants—helps explain why currency prices move the way they do.
What Makes the Forex Market Different
The forex market functions as an over-the-counter (OTC) market. This means trading happens electronically through a network of banks, brokers, and institutions rather than a single physical exchange.
| Feature | Description |
|---|---|
| Market Type | Decentralized (OTC) |
| Trading Hours | 24 hours a day, 5 days a week |
| Assets Traded | Currency pairs |
| Price Movement | Driven by supply and demand |
Because of its structure, forex allows continuous price discovery across regions.
Forex Trading Sessions Explained
Forex trading is divided into major global sessions based on financial centers. Each session has unique characteristics in terms of volume and volatility.
Major Forex Trading Sessions
| Session | Main Financial Centers | Typical Market Activity |
|---|---|---|
| Asian Session | Tokyo, Sydney | Moderate volatility |
| European Session | London, Frankfurt | High liquidity |
| North American Session | New York | Strong price movements |
The market becomes most active when sessions overlap.
Session Overlap and Market Activity
| Overlap | Why It Matters |
|---|---|
| London–New York | Highest liquidity and volume |
| Tokyo–London | Lower overlap activity |
Session overlaps often see faster price movements due to increased participation.
What Is Liquidity in Forex?
Liquidity refers to how easily a currency pair can be bought or sold without significantly affecting its price. The forex market is considered highly liquid due to its large trading volume.
| Currency Pair Type | Liquidity Level |
|---|---|
| Major pairs | Very high |
| Minor pairs | Moderate |
| Exotic pairs | Lower |
High liquidity generally results in tighter spreads and smoother price action.
Why Liquidity Matters
Liquidity influences trading conditions across the market.
| Impact Area | Effect of High Liquidity |
|---|---|
| Spreads | Lower transaction costs |
| Execution | Faster order fills |
| Volatility | More stable price movement |
Low liquidity, on the other hand, can lead to wider spreads and sudden price jumps.
Key Participants in the Forex Market
The forex market consists of multiple participants, each playing a different role.
Major Forex Market Participants

|---|---|
| Central Banks | Control monetary policy and currency supply |
| Commercial Banks | Facilitate large currency transactions |
| Financial Institutions | Manage investments and hedging |
| Corporations | Hedge international business exposure |

Role of Central Banks
Central banks influence currency value through interest rates, policy decisions, and market intervention.
| Central Bank Action | Market Impact |
|---|---|
| Interest rate changes | Currency appreciation or depreciation |
| Policy statements | Market expectations shift |
| Intervention | Direct price movement |
These actions are closely watched by market participants.
How Prices Move in the Forex Market
Currency prices fluctuate due to changes in supply and demand. Several factors influence this balance.
| Factor | Influence on Price |
|---|---|
| Economic data | Inflation, employment, GDP |
| Interest rates | Capital flow direction |
| Geopolitical events | Risk sentiment |
| Market expectations | Trader positioning |
Price movement reflects how participants interpret new information.
