What Are Forex Spreads?
The spread is the difference between the bid price (what buyers are willing to pay) and the ask price (what sellers are asking for) of a currency pair. It represents the primary cost of trading forex and is how most brokers generate revenue from your trades.
Understanding spreads is crucial because they directly impact your trading profitability. Every time you enter a trade, you start with a small loss equal to the spread amount, which you must overcome before achieving profitability.
Spread Example
If EUR/USD shows a bid of 1.2000 and ask of 1.2002, the spread is 2 pips. When you buy at 1.2002, the price must rise above 1.2002 for your trade to become profitable"”the spread represents your immediate cost.
How Spreads Are Measured
Spreads are typically quoted in pips (percentage in point), the smallest price movement in a currency pair. For most major pairs, a pip is the fourth decimal place (0.0001), while for JPY pairs, it's the second decimal place (0.01).
High-Frequency Traders (100+ lots/month)
- Choose ECN brokers: Raw spreads with commission structures offer significant savings
- Negotiate rates: High-volume traders can often get reduced commission rates
- Focus on major pairs: Stick to EUR/USD, GBP/USD, and USD/JPY for tightest spreads
- Trade during peak hours: London and New York sessions offer best liquidity
- Consider VPS hosting: Reduced latency can improve execution and reduce slippage
Medium-Frequency Traders (10-100 lots/month)
- Compare total costs: Calculate spread + commission for accurate comparison
- Avoid weekend trading: Spreads are typically 2-3x wider during low liquidity
- Use limit orders: Avoid market orders during news events when spreads widen
- Monitor swap rates: For swing trading, negative swaps can outweigh tight spreads
Low-Frequency Traders (<10 lots/month)
- Fixed spreads may work: Predictable costs with less worry about widening
- Avoid inactivity fees: Choose brokers without dormant account charges
- Minimize withdrawals: Batch withdrawals to reduce fee impact
- Focus on education: Skill improvement matters more than minor cost differences
