Imagine you’re traveling from India to Dubai. Before boarding your flight, you exchange Indian Rupees (INR) for UAE Dirhams (AED).

1Defining Forex - The Core Mechanism

What is Foreign Exchange (Forex or FX)?

Forex = FOReign EXchange

Definition: The process of exchanging one currency for another at an agreed-upon price, known as the exchange rate.

The Fundamental Transaction:

Every Forex trade involves simultaneously buying one currency and selling another. You cannot buy a currency in isolation—you always exchange it for something else.

Example:

  • You believe the Euro will strengthen vs. the US Dollar
  • You buy EUR/USD (buy Euro, sell Dollar)
  • Exchange rate: 1.0850 (1 Euro costs 1.0850 US Dollars)
  • If Euro strengthens to 1.0950, you profit 100 pips

Three Primary Functions of Forex

  1. Commercial trade: Companies convert currencies to do business globally.
  2. Hedging: Institutions lock in rates to reduce risk.
  3. Speculation: Financial institutions and traders contribute significantly to daily activity, while commercial transactions and hedging also play important roles.
2The Scale of the Market

The sheer size of the Forex market gives it unique characteristics that benefit traders.

Why it matters: This is why Forex normally provides tighter spreads and deeper liquidity.

Pro Tip

Pro tip: Major pairs are most liquid during the London/NY overlap, which means tighter spreads and better fills.

4How Currencies Are Traded

The Iron Law of Forex: You never trade a single currency in isolation. You always trade two currencies simultaneously in a pair.

Base Currency vs. Quote Currency

EUR/USD = 1.0850
  • Base (EUR): the currency you’re buying/selling
  • Quote (USD): the price to buy 1 unit of the base

Understanding Buy and Sell (Long and Short)

When you execute a trade, you're expressing a directional opinion on the base currency:

5Major Forex Trading Sessions

The Forex market's 24/5 operation is a massive advantage—but not all hours are equal.

The Four Primary Trading Sessions

Asian

7 PM – 4 AM EST

Lower liquidity, range-bound

European

2 AM – 11 AM EST

Highest liquidity

North American

8 AM – 5 PM EST

US news-driven

Pacific

5 PM – 2 AM EST

Lowest liquidity

Session Timeline

Sydney→Tokyo→London→New York

Best time to trade: London/New York overlap (8 AM – 12 PM EST).
Avoid: Late Asian session and late Friday when liquidity drops.

Pro Tip

Professional Session Strategy: Trade EUR/USD, GBP/USD during London/NY overlap (8 AM - 12 PM EST) for tightest spreads and highest probability setups. Trade USD/JPY during Asian/London overlap (2 AM - 4 AM EST). Avoid trading major pairs during dead Asian session (9 PM - 2 AM EST) unless you're targeting range-bound strategies.
