Slippage is a common part of online trading that every trader should understand before investing in forex, stocks, cryptocurrencies, commodities, or CFDs. While many beginners focus on trading strategies and market analysis, they often overlook how trade execution can affect profits and losses.
Slippage occurs when your trade is executed at a different price than expected. Sometimes this difference works in your favor, but in many cases, it can increase your trading costs or reduce your profits.
In this beginner-friendly guide, you’ll learn what slippage is, why it happens, the different types of slippage, how it affects trading, and practical ways to reduce it.
What Is Slippage in Trading?
Slippage is the difference between the expected execution price of a trade and the actual price at which the order is filled.
It usually happens because financial markets move very quickly, especially during periods of high volatility or low liquidity.
For example:
- You place a Buy Order at EUR/USD 1.1000
- Your order is executed at 1.1003
The trade experienced:
Slippage is normal in fast-moving markets and can occur in almost every financial market.
How Does Slippage Work?
When you place a market order, your broker tries to execute it at the best available price.
However, if prices change before your order reaches the market, your execution price may differ from your requested price.
Example
Expected Buy Price:
1.2050
Actual Execution:
1.2052
Difference:
2 pips of slippage
This happens because prices changed before the order could be filled.
Types of Slippage
There are two main types of slippage.
1. Negative Slippage
Negative slippage occurs when your order is executed at a worse price than expected.
Example
Expected Buy Price:
1.1000
Actual Price:
1.1005
The trader pays a higher price.
Negative slippage increases trading costs.
2. Positive Slippage
Positive slippage happens when your trade is executed at a better price than expected.
Example
Expected Buy Price:
1.1000
Actual Price:
1.0998
The trader receives a better entry price.
Positive slippage improves profitability.
Why Does Slippage Happen?
Several factors contribute to slippage.
1. High Market Volatility
Major news events can move prices rapidly.
Examples include:
- Interest rate decisions
- Inflation reports
- Employment data
- GDP announcements
During these events, prices can change within milliseconds.
2. Low Market Liquidity
When there are fewer buyers and sellers, there may not be enough orders available at your requested price.
This is common with:
- Exotic currency pairs
- Small-cap stocks
- Low-volume cryptocurrencies
3. Large Order Size
Very large orders may require multiple price levels to complete execution.
This often causes partial fills and slippage.
4. Market Gaps
Markets sometimes open significantly higher or lower than the previous closing price.
This frequently occurs:
- After weekends
- Following major news
- During unexpected geopolitical events
Stop-loss orders may execute at the next available price rather than the exact stop level.
5. Slow Trade Execution
Poor internet connections or slow broker infrastructure may increase execution delays.
Modern brokers invest heavily in fast trading servers to reduce slippage.
Slippage Example
Suppose you place the following trade.
Buy EUR/USD:
Expected Price:
1.1000
Actual Execution:
1.1004
Difference:
4 pips
If you’re trading one standard lot, where one pip is approximately $10, the additional cost equals:
4 × $10 = $40
Although the trade may still become profitable, slippage increases the initial trading cost.
Slippage vs Spread
Many beginners confuse slippage with spreads.
Both affect profitability, but they are different concepts.
Markets Where Slippage Occurs
Slippage can happen in almost every financial market.
Forex Trading
High-impact economic news often increases slippage.Stock Trading
Low-volume stocks may experience significant price changes between order placement and execution.
Cryptocurrency Trading
Crypto markets operate 24/7 and often experience rapid price swings.
Slippage is common during periods of heavy volatility.
Commodity Trading
Gold, silver, oil, and natural gas may experience slippage during major market events.
CFD Trading
CFD traders may encounter slippage whenever the underlying market moves rapidly.
How to Reduce Slippage
Although slippage cannot be completely eliminated, traders can reduce its impact.
Trade During High Liquidity
Major trading sessions generally provide better execution.
The London and New York sessions usually have the highest liquidity.
Avoid Major News Releases
Economic announcements often create sudden price movements.
Waiting until volatility decreases can improve execution quality.
Use Limit Orders
Unlike market orders, limit orders only execute at your specified price or better.
This helps control execution prices.
Choose a Reliable Broker
A high-quality broker should provide:
- Fast execution
- Deep liquidity
- Low latency
- Transparent pricing
Execution quality is just as important as low spreads.
Avoid Extremely Large Orders
Breaking large positions into smaller trades may reduce slippage in less liquid markets.
Advantages of Understanding Slippage
Learning about slippage helps traders:
- Improve risk management
- Choose better entry points
- Select reliable brokers
- Understand real trading costs
- Avoid unrealistic profit expectations
Professional traders always consider execution quality as part of their overall trading strategy.
Common Slippage Mistakes
Ignoring Execution Quality
Many beginners choose brokers based only on bonuses or leverage instead of execution speed.
Trading During Major News
Volatility increases the likelihood of significant slippage.
Using Only Market Orders
Market orders prioritize execution rather than price.
Limit orders provide greater price control.
Choosing Poor Liquidity Markets
Low-volume markets often produce larger price gaps.
Expecting Zero Slippage
No broker can completely eliminate slippage during fast-moving markets.
