Understanding Bid/Ask Spreads
Learn what spreads are, how they affect your trading costs, and strategies to minimize spread expenses in forex trading.
What is the Bid/Ask Spread?
Bid Price
The price you SELL at
The price at which the market (broker) will BUY the base currency from you.
EUR/USD Bid = 1.0950 means you sell 1 EUR for 1.0950 USD
Ask Price (Offer Price)
The price you BUY at
The price at which the market (broker) will SELL the base currency to you.
EUR/USD Ask = 1.0952 means you buy 1 EUR for 1.0952 USD
Spread
Your transaction cost
The difference between Ask and Bid prices. This is the broker's commission.
1.0952 (Ask) - 1.0950 (Bid) = 2 pips spread
Visual Example: EUR/USD
If you BUY: You pay 1.0952 (the higher Ask price)
If you immediately SELL: You receive 1.0950 (the lower Bid price)
Instant loss: 2 pips = The spread cost
To break even: Price must move 2 pips in your favor

Common Spread-Related Mistakes
Ignoring Spread in Strategy
Problem:
Scalping with 3-pip spread = need 6 pips to break even
Solution:
Calculate break-even before trading. Need tight spreads for scalping.
Trading Exotics Without Checking
Problem:
50-pip spread eats 50% of small moves
Solution:
Stick to majors unless you have specific exotic strategy and large targets.
Opening Trades During Low Liquidity
Problem:
Weekend gaps, 3 AM trades = 3x normal spread
Solution:
Trade during London/NY sessions. Avoid Sundays and late nights.
Not Comparing Broker Spreads
Problem:
Paying 3 pips when competitors offer 1 pip
Solution:
Use broker comparison tools. Switch to low-spread broker.
