Currency Pairs — Base, Quote, Major, Minor, Exotics 💱

A currency pair is always quoted with a three-letter ISO code for each currency.

Example: EUR/USD (Euro vs. US Dollar)

The Two-Part Structure

Every currency pair has two components, always in the same order:

BASE / QUOTE
 ↑       ↑
Left   Right

The Base Currency (First/Left)

Definition: The first currency in the pair, always on the LEFT

Characteristics:

• Reference unit (always equal to 1)
• The currency you're expressing an opinion about
• When you BUY the pair, you buy the Base
• When you SELL the pair, you sell the Base

The Quote Currency (Second/Right)

Definition: The second currency in the pair, always on the RIGHT

Characteristics:

• Also called the Counter Currency
• The amount needed to purchase 1 unit of Base
• When you BUY the pair, you sell the Quote
• When you SELL the pair, you buy the Quote

How to Read the Exchange Rate

Quote Format:

EUR/USD = 1.0850

Translation:

1 Euro costs 1.0850 US Dollars

Buy vs. Sell: The Critical Distinction

Your trade direction is ALWAYS defined by the BASE currency.

With 180+ currencies globally, the market is divided into three categories based on liquidity, spreads, and volatility:

The Three Categories

Why This Matters:

Liquidity = Ease of Execution:

• High liquidity: Instant fills at quoted price
• Low liquidity: Slippage (fills at worse price)

Spread = Transaction Cost:

• Tight spread (0.5 pips): $5 cost per Standard Lot
• Wide spread (40 pips): $400 cost per Standard Lot

Volatility = Risk/Reward:

• Moderate: 50-100 pips daily range (predictable)
• Very High: 200-500 pips daily range (unpredictable gaps)

Major pairs are the backbone of Forex and should be your exclusive focus as a beginner.

Definition

Major Pair = Any pair that includes the US Dollar (USD) + One of seven major currencies

The 7 Major Pairs

Combined: These 7 pairs account for ~61% of total daily Forex volume

Why Majors Are Preferred for Beginners

1. Supreme Liquidity

EUR/USD Liquidity:

• $1.8 trillion traded daily
• Bid-ask spread: 0.5-0.8 pips during London/NY overlap
• Instant execution (even 10+ Standard Lots)

2. Tight Spreads (Lowest Cost)

Cost Comparison (1.00 Standard Lot):

Impact Over 100 Trades:

• EUR/USD: $800 total cost
• USD/TRY: $40,000 total cost

50x cost difference!

Which Major to Start With?

Beginner Recommendation: EUR/USD

Why:

• Most liquid (tightest spreads: 0.5-0.8 pips)
• Most analyzed (abundant free resources)
• Most stable (moderate volatility)
• Best trading hours: London/NY overlap (8 AM - 12 PM EST)

Progression Path:

1. Months 1-3: EUR/USD only (master one pair)
2. Months 4-6: Add GBP/USD (higher volatility practice)
3. Months 7-12: Add USD/JPY (different dynamics, Asian session)
4. Year 2+: Explore AUD/USD, USD/CAD (commodity-linked)

Once comfortable with Majors, traders explore Minor Pairs for unique opportunities.

Definition

Minor Pair (Cross) = Two major currencies, NO USD

Examples:

• EUR/GBP (Euro vs. Pound)
• EUR/JPY (Euro vs. Yen)
• GBP/JPY (Pound vs. Yen)

Popular Cross Categories

1. Euro Crosses

2. Yen Crosses

Advantages of Crosses

1. Unique Price Action

Crosses respond to TWO economies simultaneously:

Example: EUR/GBP

• Not affected by USD news (NFP, Fed)
• Moves on Europe vs. UK data
• ECB dovish + BoE hawkish = EUR/GBP falls significantly

2. Higher Volatility (More Pips)

GBP/JPY ("The Beast"):

• Average Daily Range: 150-200 pips
• EUR/USD ADR: 60-80 pips

For swing traders: GBP/JPY offers 2-3x the pip potential per move

When to Trade Crosses

Ideal Scenarios:

1. ✅ You're intermediate trader (6+ months profitable on Majors)
2. ✅ USD pairs are ranging (no clear trend)
3. ✅ You have clear directional bias on both currencies
4. ✅ You trade during peak liquidity (London session for EUR/GBP)

Avoid Crosses When:

1. ❌ You're a beginner (stick to Majors)
2. ❌ You don't understand BOTH economies
3. ❌ Trading during low liquidity (Asian session for EUR/GBP)

Exotic pairs represent the extreme end of Forex—not recommended for beginners or even intermediate traders.

Definition

Exotic Pair = One Major Currency (usually USD) + One Emerging/Smaller Economy Currency

Examples:

The Extreme Trade-Offs

1. Very Low Liquidity

Problem:

• Few market participants
• Large bid-ask spreads
• Difficult to fill large orders

2. Extremely Wide Spreads

Cost Comparison (1.00 Standard Lot):

You start EVERY trade -$500 down on USD/TRY

3. Extreme Volatility & Gaps

USD/TRY Example (2018 Turkish Currency Crisis):

• Opened Monday at 5.50
• Flash crashed to 7.20 in hours (+1,700 pips)
• Many stop losses gapped through (filled 500 pips worse than requested)

Traders lost entire accounts in minutes

Who Should Trade Exotics?

Only Trade Exotics If:

• ✅ You have 3+ years profitable trading experience
• ✅ You deeply understand the emerging market economy
• ✅ You have advanced risk management (max 0.5% risk per trade)
• ✅ You accept potential total loss of position due to gaps

Beginners: NEVER trade exotics

Summary

Strategy:

• Months 1-3: EUR/USD only
• Months 4-12: Add 1-2 Majors
• Year 2+: Specialize in 2-3 pairs that match your session and strategy
