Understanding Forex Spreads and Commissions
Every time you place a forex trade, you pay a cost. Understanding these costs is crucial for profitable trading.
What is a Spread?
The spread is the difference between the bid (sell) price and the ask (buy) price of a currency pair.
Example: If EUR/USD shows Bid: 1.0800 / Ask: 1.0802, the spread is 2 pips.
When you open a trade, you immediately start with a small loss equal to the spread. The price must move in your favor by at least the spread amount before you break even.
Types of Spreads
Fixed Spreads:
- Remain constant regardless of market conditions
- Easier to calculate trading costs
- Usually wider than variable spreads
Variable (Floating) Spreads:
- Change based on market liquidity and volatility
- Can be very tight during high-liquidity sessions
- May widen significantly during news events or low-liquidity periods
Typical Spreads for Major Pairs
| Pair | Typical Spread | During News |
|---|---|---|
| EUR/USD | 1.0-1.7 pips | 3-8 pips |
| GBP/USD | 1.2-2.0 pips | 4-12 pips |
| USD/JPY | 1.0-1.5 pips | 3-8 pips |
| AUD/USD | 1.2-1.8 pips | 3-10 pips |
How Spreads Affect Your Trading
The tighter the spread, the less the market needs to move for you to profit. This is especially important for:
- Scalpers — who target small price movements
- EAs — automated systems that may trade frequently
- High-frequency traders — where costs compound rapidly
Calculating Your Trading Costs
Cost per trade = Spread × Lot Size × Pip Value
For EUR/USD with a 1.5 pip spread trading 1 standard lot:
- Cost = 1.5 × $10 = $15 per round trip
For a micro lot (0.01):
- Cost = 1.5 × $0.10 = $0.15 per round trip
Tips to Minimize Trading Costs
- Choose a broker with competitive spreads — compare across multiple brokers
- Trade during high-liquidity sessions — London and New York sessions offer tightest spreads
- Avoid trading during major news releases — spreads can widen dramatically
- Focus on major pairs — they have the tightest spreads
- Consider your trading frequency — fewer, higher-quality trades reduce total cost
Commission-Based vs Spread-Based Accounts
Some brokers offer accounts with raw spreads (near zero) plus a fixed commission per lot, while others build the cost into wider spreads:
- Standard Account: Wider spread (e.g., 1.6 pips), no commission
- Raw/ECN Account: Tight spread (e.g., 0.1 pips) + commission (e.g., $3.50/lot per side)
Calculate which option is cheaper based on your trading volume and style.
