Forex Broker Spreads Explained

The spread is the difference between the buy (ask) and sell (bid) price. It's the primary cost of trading forex and directly impacts your profitability. Understanding spreads helps you choose the right broker and minimize costs.

What is the Spread?

Definition

Spread = Ask Price - Bid Price

Example:

• Bid (sell price): 1.1000
• Ask (buy price): 1.1002
• Spread: 2 pips (0.0002)

Why It Exists

The spread compensates:

• Brokers for their services
• Liquidity providers for risk
• Market participants for making markets

How It Affects You

When you enter a trade:

• You buy at ask (higher)
• You sell at bid (lower)
• You start with a small loss (the spread)
• Trade must move in your favor to profit

Types of Spreads

Fixed Spreads

Characteristics:

• Stay constant regardless of market conditions
• Set by broker (usually market makers)
• Don't widen during volatility

Advantages:

• Predictable costs
• Know exact cost before trading
• Good for beginners

Disadvantages:

• Usually wider than variable
• May have requotes during volatility
• Less competitive overall

Variable (Floating) Spreads

Characteristics:

• Change based on market conditions
• Tighter during liquid times
• Wider during low liquidity or news

Advantages:

• Often tighter overall
• More competitive
• Reflects true market

Disadvantages:

• Unpredictable during events
• Can widen significantly
• Requires monitoring

Spread Comparison by Pair

Typical Spreads

Why Pairs Differ

Tighter Spreads:

• More liquidity
• Higher trading volume
• Major pairs

Wider Spreads:

• Less liquidity
• Lower trading volume
• Exotic pairs

When Spreads Widen

Low Liquidity Times

Asian Session for EUR/USD:

• Less volume
• Spreads widen
• Normal widening

Holidays:

• Fewer participants
• Less liquidity
• Wider spreads

News Events

Before Major News:

• Liquidity providers step back
• Uncertainty increases
• Spreads widen significantly

During News:

• Extreme volatility
• Spreads may triple or more
• No new position 30 minutes either side of a high-impact release

Market Open/Close

Session Transitions:

• Brief wider spreads
• Returns to normal quickly
• Usually minor impact

Calculating Spread Cost

Per Trade Cost

Formula:

Spread Cost = Spread (pips) × Pip Value × Lots

Example:

• Spread: 1.5 pips
• Pip Value: $10 (standard lot)
• Lots: 1
• Cost: 1.5 × $10 × 1 = $15

Monthly/Yearly Cost

Example:

• 20 trades per month
• Average spread cost: $15
• Monthly cost: $300
• Yearly cost: $3,600

This adds up.

Comparing Brokers

Broker A: 1.8 pip spread, no commission Broker B: 0.3 pip spread + $7 commission

Per Standard Lot:

• Broker A: 1.8 × $10 = $18
• Broker B: 0.3 × $10 + $7 = $10

Broker B is cheaper despite commission.

Spread as Percentage of Target

Why This Matters

Your target size affects spread impact:

Example 1: Scalping

• Target: 10 pips
• Spread: 2 pips
• Spread as % of target: 20%

Example 2: Swing Trading

• Target: 100 pips
• Spread: 2 pips
• Spread as % of target: 2%

Key Insight: Spread matters more for short-term trading.

Minimizing Spread Costs

Choose Lower Spread Broker

Compare total costs:

• Spread + commission
• Not just advertised spread
• Multiple pairs if you trade them

Trade Major Pairs

Stick to:

• EUR/USD
• GBP/USD
• USD/JPY
• AUD/USD

These have tightest spreads.

Trade During High Liquidity

Best Times:

• London session (3 AM - 12 PM ET; 12:00-21:00 GST in winter, 11:00-20:00 in summer)
• New York session (8 AM - 5 PM ET; 17:00-02:00 GST in winter, 16:00-01:00 in summer)
• Overlap (8 AM - 12 PM ET; 17:00-21:00 GST in winter, 16:00-20:00 in summer)

Avoid News Events

Our rule: no new position from 30 minutes before to 30 minutes after a high-impact release (central-bank decisions, NFP, CPI, GDP). Spreads widen and stops slip. If the move is real, it will still be there at minute 31.

• Spreads spike dramatically
• Wait for spreads to normalize
• Check spread before trading

Consider Your Strategy

Scalpers:

• Need tightest possible spreads
• ECN accounts often better
• Every pip matters

Swing Traders:

• Spread less critical
• Can accept slightly wider
• Focus on other factors

Spread Monitoring

Check Before Every Trade

Many platforms show:

• Current spread
• Historical spread
• Spread indicator

Use Spread Alert Tools

Some tools:

• Alert when spread exceeds threshold
• Track spread history
• Compare brokers

Keep Records

Track:

• What spread you paid
• At what time
• Total spread cost monthly

Commission vs Spread

Commission-Based (ECN)

Structure:

• Very tight spread
• Fixed commission per lot
• Separate charges

Example:

• Spread: 0.2 pips
• Commission: $3.50 per side = $7 round trip

Spread-Only

Structure:

• No separate commission
• Spread includes markup
• All-in-one pricing

Example:

• Spread: 1.5 pips
• Commission: $0

Which is Better?

For High Volume:

• ECN usually cheaper
• Commission worth it
• Tighter spreads matter

For Low Volume:

• Spread-only may be fine
• Simpler structure
• Less to calculate

Red Flags

Spread Issues to Watch

Constant Wide Spreads:

• Even during liquid times
• Much wider than advertised
• Sign of poor pricing

Extreme News Widening:

• Spreads 10x normal
• Stays wide too long
• Excessive markup

Inconsistent Spreads:

• Varies wildly
• No pattern
• Manipulation possible
