Spread in Trading: Definition, Calculation, and Risk Management Strategies

Spread What Is It? Understanding Hidden Costs in Every Transaction

In the world of financial trading, spread is an indispensable concept. It simply refers to the difference between two price levels offered by liquidity providers – specifically the bid price (buy) and the ask price (sell).

When you want to trade a currency pair like EUR/USD, the market will display two different prices:

• Bid: The price at which you can sell the asset
• Ask: The price at which you can buy the asset

The difference between these two prices is the spread. If EUR/USD is quoted as 1.1021/1.1023, then the spread = 1.1023 – 1.1021 = 0.0002, equivalent to 2 pips (a pip is the smallest price movement unit, 1 pip = 0.0001).

Spread Measured in Pips – The Smallest but Important Unit

Although pips seem like a very small number, when trading large volumes, they accumulate into significant costs. For example, if you trade 1 lot of EUR/USD with a 2-pip spread, you will lose about $20 just to open the position. With 10 lots, the spread cost increases to $200.

Why Does Spread Exist?

Spread is not a random “lubrication” cost. It serves very important purposes in the market system:

Protecting Market Makers (Market Maker): When a broker accepts a trade with you, they are taking on risk. If they buy EUR from you at 1.1021 but haven’t found a seller yet, they must hold this EUR. If the price rises to 1.1030 before they sell, they lose money. The spread acts as “insurance” to offset this risk.

Ensuring Liquidity: Spread allows the market to stay active. It incentivizes market makers to compete by offering better prices.

Broker Income: Instead of charging separate fees, brokers earn from the spread. This is also why some brokers claim “no commission” – because they include the cost within the spread.

Two Types of Spread: Fixed and Variable

Fixed Spread – Accurate Cost Prediction

Dealers operating under the Dealing Desk (Dealing Desk) model offer fixed spreads. They buy large volumes from liquidity providers and sell in smaller lots to traders.

Advantages:

• Low capital requirement, suitable for beginners
• Easy to predict costs, better risk management
• No surprises in trading costs

Disadvantages:

• Requotes may occur: When the market moves quickly, brokers cannot maintain fixed spreads. They will requote (offer a new price), often worse than your initial price
• Slippage: In volatile market conditions, the actual price you get may differ significantly from your intended price

Variable Spread – Transparent but Unstable

Dealers following the No-Dealing Desk (Non-Dealing Desk) model provide floating spreads. They receive prices from multiple liquidity providers and pass them directly to traders without intervention.

Advantages:

• Eliminates requotes – no unexpected surprises
• More transparent prices from competitive sources
• Suitable for fast traders

Disadvantages:

• Spread can widen significantly during high volatility, especially around major news releases
• Not ideal for scalpers (scalping) as spread can eat into all profits
• News traders may face difficulties when spreads suddenly widen

How to Calculate Spread – Simple Formula

The calculation is very basic:

Spread = Ask Price – Bid Price

Real-world example:

• EUR/USD Bid Price: 1.14500
• EUR/USD Ask Price: 1.14509
• Spread = 1.14509 – 1.14500 = 0.00009 = 0.9 pips

To calculate the actual monetary cost of the spread:

• For 1 EUR/USD contract, spread cost = 0.9 pips × $10/pip = $9
• For 10 contracts, spread cost = $90

Note: The pip value varies depending on the currency pair, asset, and trading volume on each platform.

Factors Affecting Spread

Spread is not always the same. It varies based on:

1. Liquidity (Liquidity)

• Popular pairs like EUR/USD, GBP/USD have high liquidity, usually narrower spreads (0.5-1 pip)
• Less common or emerging market currencies tend to have lower liquidity, wider spreads (5-20 pips or more)

2. Trading Volume (Trading Volume)

• During peak trading hours (Asian, European, American sessions overlap), spreads tend to narrow due to high buying and selling activity
• Outside trading hours or weekends, spreads widen due to lower liquidity

3. Market Volatility (Volatility)

• In stable periods, spreads are narrow
• During high volatility (economic data releases, central bank decisions), spreads widen significantly

4. Global Market Conditions

• Stock market downturns → panic selling → reduced liquidity → wider spreads
• Geopolitical events or crises can cause sudden spread widening

Spread Widening Phenomenon – When Spreads Suddenly Increase

Spread widening (spread widening) occurs when the bid-ask difference exceeds normal levels. For example, EUR/USD usually has a 1 pip spread but suddenly jumps to 5-10 pips or more.

Times When Spread Widens

Cross-day trading sessions:

• Liquidity is very thin, few traders active
• Example: End of Asian session (around 6-8 AM UTC) and before European session opens

Economic news releases:

• Before inflation data, GDP, interest rate decisions, brokers often widen spreads to protect their interests
• After major news, if the market reacts strongly, spreads may continue to widen

Weekends or holidays:

• Low liquidity → wider spreads

Market crises:

• Geopolitical events, financial crises, or economic instability cause traders to panic → spreads widen dramatically

Strategies to Minimize Spread Costs

If you want to optimize your trading, avoid periods of wide spreads:

Method 1: Trade During High Liquidity Hours

Focus on trading when there is high participation:

• European hours: 8:00 - 12:00 UTC (when the European market opens)
• American hours: 13:00 - 17:00 UTC (when the US market opens)
• Overlap hours: 13:00 - 15:00 UTC (when both Europe and US are active) – the best time with the narrowest spreads

Method 2: Choose Major Currency Pairs

• EUR/USD, GBP/USD, USD/JPY, USD/CHF: spreads usually 0.5-1.5 pips
• Avoid less traded or emerging pairs

Method 3: Avoid Trading Before Major News

• Especially avoid before interest rate, inflation, or GDP announcements
• If trading is necessary, use stop-loss orders to manage risk

Method 4: Plan for Overnight Trading

• If holding positions overnight, be prepared for wider spreads
• Consider closing positions before the end of the session instead of holding overnight

Spread in Other Markets Besides Forex

Stock Market

Spread is the difference between the bid (investors willing to buy) and ask (investors willing to sell). Small and large stocks have narrow spreads, small-cap stocks have wider spreads.

Bond Market

Spread has a different meaning – it is the yield spread (yield spread) between two bonds. For example: if US Treasury bonds yield 5% and UK government bonds yield 6%, spread = 1%.

Futures Commodity Market

Spread is the price difference of the same commodity at different delivery dates. For example: January wheat futures might be priced at 500, October at 520, spread = 20.

Cryptocurrency Market

Bitcoin and Ethereum on different exchanges have different spreads. Exchanges with high liquidity have narrow spreads, smaller exchanges have wider spreads.

Fixed vs Floating Spread – Which Choice Is Suitable?

There is no absolute answer – it all depends on your trading style:

Choose Fixed Spread If:

• You are a long-term trader (swing trading, position trading)
• Limited capital, need precise cost control
• Want to avoid requotes and slippage

Choose Floating Spread If:

• You trade frequently during high liquidity hours (high liquidity)
• You have a large account and can tolerate volatility
• Need fast execution, avoid requotes
• Prioritize transparency

Conclusion: Control Spread to Maximize Profits

Spread is not an enemy, but a natural part of the market system. However, if you understand how it works, you can:

• Choose brokers with suitable spreads for your trading style
• Trade at the best times when spreads are narrowest
• Avoid high-risk periods
• Calculate trading costs accurately before executing
• Manage risks more effectively
