Understanding Bid/Ask Spread in Forex Trading
The bid/ask spread in forex trading is the difference between the bid price (where you can sell a currency pair) and the ask price (where you can buy it), measured in pips. It’s the primary cost of trading, as brokers and market makers profit from this spread.
As Dr. John Murphy, a renowned technical analyst, states, “The bid/ask spread is the silent cost that every trader must master to ensure profitability.”
How the Bid/Ask Spread Works
For a currency pair like EUR/USD quoted at 1.26572/1.26583, the bid price is 1.26572, the ask price is 1.26583, and the spread is 1.1 pips (0.00011). When you buy, you pay the ask price; when you sell, you receive the bid price. The spread is calculated as:
[
\text{Spread} = \text{Ask Price} – \text{Bid Price}
]
This cost is incurred per round-trip trade (buy and sell), directly affecting profitability.
Historical Context
The bid/ask spread became standardized with the modern forex market post-Bretton Woods in the 1970s, ensuring transparent pricing. In 2025, its significance is amplified by AI-driven trading and volatile market conditions, as reported in July 2025 financial news.
Factors Influencing Bid/Ask Spreads
Liquidity
Highly liquid pairs like EUR/USD have tight spreads (0.5-2 pips) due to high trading volume, as noted by Investopedia. Less liquid pairs like USD/TRY have wider spreads (5-10 pips) due to fewer participants.
Volatility
Spreads widen during high-volatility events, such as the July 2025 Fed announcements, increasing trading costs, as reported by Reuters.
Time of Day
Spreads are tightest during the London-New York overlap (8 AM–12 PM EST) and wider during low-volume Asian sessions, per Wikipedia.
Currency Pair Type
- Major Pairs: EUR/USD, USD/JPY (0.5-2 pips).
- Minor Pairs: EUR/GBP (2-5 pips).
- Exotic Pairs: USD/TRY (5-10 pips).
Broker Policies
Brokers offer fixed or variable spreads, with ECN brokers providing tighter variable spreads but charging commissions, as explained by Fortrade Blog.
Types of Bid/Ask Spreads
Fixed Spreads
Fixed spreads remain constant, offering predictability, ideal for beginners. However, they may be higher during stable markets, per FBS.
Variable Spreads
Variable spreads fluctuate with market conditions, tightening during stability but widening during volatility, common with ECN brokers, per Bound.co.
Controversy: Fixed vs. Variable
Some traders prefer fixed spreads for cost certainty, while others favor variable spreads for potential savings in calm markets, sparking debate over cost efficiency.
Impact of Bid/Ask Spread on Trading Strategies
Scalping
Scalpers target 5-10 pips per trade, requiring tight spreads (0.5-1 pip) to maintain profitability. A 2-pip spread on EUR/USD reduces a 5-pip target to 3 pips net profit.
Day Trading
Day traders aim for 20-50 pips, tolerating slightly wider spreads (1-2 pips), as spreads are less impactful over larger moves.
Swing Trading
Swing traders target 50-100 pips, making spreads (1-2 pips) negligible compared to potential profits.
Position Trading
Long-term traders targeting 100+ pips are least affected by spreads, as costs are minimal relative to large price movements.
Calculating Bid/Ask Spread Costs
Spread Cost Formula
[
\text{Spread Cost} = \text{Spread (in pips)} \times \text{Pip Value} \times \text{Lot Size}
]
For EUR/USD with a 1-pip spread, $10 pip value, and 1 standard lot:
- Spread Cost = ( 1 \times 10 \times 1 = 10 \text{ USD} ).
Example
A scalper trades 10 micro lots (10,000 units) of GBP/USD with a 1.5-pip spread ($0.15/pip):
- Spread Cost = ( 1.5 \times 0.15 \times 10 = 2.25 \text{ USD per trade} ).
Over 100 trades, total cost = $225, highlighting spread impact.
Bid/Ask Spread in Different Currency Pairs
Major Pairs
EUR/USD and USD/JPY have tight spreads (0.5-2 pips) due to high liquidity, ideal for scalping.
Minor Pairs
EUR/GBP and AUD/NZD have moderate spreads (2-5 pips), suitable for day trading.
Exotic Pairs
USD/TRY and EUR/ZAR have wide spreads (5-10 pips), increasing costs for high-volatility trades.
