1. What Is the Forex Market and How Does It Function?
The Foreign Exchange (Forex or FX) market is the global decentralized financial network where national currencies are bought, sold, and exchanged. With an astounding daily trading volume exceeding $7.5 trillion, it represents the single most liquid and dynamic financial ecosystem on Earth—eclipsing the New York Stock Exchange by more than twenty-fold.
Unlike equity markets like the NASDAQ or London Stock Exchange, forex features no central physical exchange. Instead, transactions occur Over-the-Counter (OTC) via electronic interbank networks linking central banks, multinational commercial banks, sovereign funds, asset managers, and retail brokers around the clock from Sunday evening to Friday afternoon.
2. Reading Currency Pairs: Base vs. Quote
In forex, currencies are always traded in pairs. When you enter a position, you are simultaneously purchasing one currency while selling another:
The quoted exchange rate indicates how many units of the quote currency are required to buy one single unit of the base currency. In the example above, 1 Euro costs exactly 1.0850 US Dollars.
- Major Currency Pairs: Pairs that pair the US Dollar with other major economies (EUR/USD, GBP/USD, USD/JPY, USD/CHF, AUD/USD, USD/CAD, NZD/USD). They feature the tightest spreads and deepest liquidity.
- Cross Pairs (Minors): Pairs composed of major currencies excluding the US Dollar (EUR/GBP, EUR/JPY, GBP/JPY, AUD/CAD).
- Exotic Pairs: Pairs consisting of one major currency paired with a developing economy currency (USD/ZAR, EUR/TRY). They feature high volatility and wide transaction spreads.
3. The 4 Global Trading Sessions and Best Hours to Trade
Because global financial centers open and close continuously, trading revolves around four primary market sessions:
Opens the trading week; modest liquidity focused on AUD and NZD pairs.
Driven by Japan, China, and Singapore. Major focus on JPY crosses and news releases.
The financial powerhouse. Accounts for over 35% of all global forex transaction volume.
Heavy institutional activity driven by US economic reports, Wall Street, and the Federal Reserve.
4. Pips, Lots, and Leverage: The Building Blocks
Every trade order requires understanding three fundamental parameters:
- Pips (Percentage in Point): The standardized 4th decimal measurement (0.0001) for currency fluctuation (2nd decimal 0.01 for JPY).
- Lot Sizing: Contracts are executed in standardized unit bundles: Standard Lots (100,000 units), Mini Lots (10,000 units), and Micro Lots (1,000 units).
- Broker Leverage: The collateral ratio that enables traders to hold positions larger than their account equity. At 1:100 leverage, a $1,000 margin deposit controls a $100,000 position.
