What Is Slippage in Trading?

A Complete Beginner’s Guide to Understanding Slippage

What Is Slippage in Trading? In our educational series, we always aim to explain how trading really works in a simple and practical way. Today, we’re talking about one of the most important concepts every trader should understand: slippage.

Many traders focus only on charts and strategies, but execution matters just as much. Slippage can affect your profits, losses, risk management, and even the broker you choose to trade with.

Whether you trade forex, stocks, crypto, commodities, or indices, understanding slippage can help you make smarter trading decisions and avoid unexpected surprises in fast-moving markets.

Let’s dive in.

What Is Slippage in Trading?

Slippage is the difference between the price you expect for a trade and the actual price at which the trade is executed.

It usually happens when the market moves very quickly or when there isn’t enough liquidity available to fill your order at the exact price you requested.

In simple terms, you click “Buy” or “Sell” at one price, but the market executes your trade at a slightly different price.

Simple Example of What Is Slippage in Trading

Slippage can happen in both buy and sell trades and exists in almost every financial market.

For example:

• If you expect to buy an asset at $100 but your order gets filled at $100.25, this is negative slippage.
• If your order gets filled at $99.85 instead, this is positive slippage because you received a better price.

How Does Slippage Work?

Before really diving deeper into what is slippage in trading, it is important to understand that slippage usually happens during periods of high volatility when prices move faster than the market can process orders.

This often occurs when traders use market orders, which are designed to execute immediately at the best available price.

For example:

• A stop-loss or take-profit order can experience slippage because once triggered, it becomes a market order.
• Large orders can also create slippage if there isn’t enough liquidity available at the desired price.
• Even limit orders may experience execution issues if the market moves too quickly.

Although slippage is often seen as negative, it can sometimes work in the trader’s favor through positive slippage.

Types of Slippage

To fully understand what is slippage in trading, traders should know that there are different types of slippage.

Positive Slippage

Positive slippage happens when your trade executes at a better price than expected.

Example:

• You want to buy at 1.2050
• Your trade executes at 1.2045
• You gain a 5-pip advantage

Negative Slippage

Negative slippage happens when your trade executes at a worse price than expected.

Example:

• You want to buy at 1.4040
• Your trade executes at 1.4045
• You lose 5 pips on entry

Why Does Slippage Happen?

Understanding why slippage happens is very important when learning what is slippage in trading and how it affects execution quality.

1. High Market Volatility

Prices can move extremely fast during:

• Economic news releases
• Interest rate decisions
• Earnings reports
• Political events
• Geopolitical tensions

Common examples:

• FOMC announcements
• Inflation reports
• NFP reports
• Unexpected global news

2. Low Liquidity

Slippage becomes more likely when there are not enough buyers or sellers available at your chosen price.

This commonly happens during:

• Overnight trading
• Weekends
• Holidays
• Low-volume sessions
• Small cryptocurrency markets

3. Market Orders

A market order executes immediately at the best available price.

If the market moves rapidly, the final execution price may differ from what you originally saw on your screen.

4. Large Orders

Large trades can move the market themselves, especially in low-liquidity markets.

Slippage in Different Markets

What Is Slippage in Forex Trading?

In forex trading, slippage happens when your trade is executed at a different price than expected due to rapid market movement or lower liquidity.

For example, exotic currency pairs such as USD/HUF usually experience more slippage than major pairs like EUR/USD because they have lower trading volume.

Slippage is more common:

• During major economic news releases
• In highly volatile conditions
• During holidays or quieter trading sessions
• In less popular currency pairs

Major forex pairs typically experience lower slippage because they have tighter spreads and higher liquidity.

What Is Slippage in Crypto Trading?

What is slippage in trading when it comes to crypto markets? Slippage is very common in cryptocurrency trading because crypto markets are highly volatile.

When prices move quickly, your order may not execute at the exact price you selected.

For example:

• If you try to buy Bitcoin during a sharp rally, the price may rise before your order is fully executed, causing negative slippage.

Crypto slippage often increases:

• During strong market volatility
• In low-liquidity coins
• During sudden news events
• When large orders are placed

Since crypto markets operate 24/7, slippage is considered a normal part of crypto trading.

What Is Slippage in Stock Trading?

In stock trading, slippage occurs when shares are bought or sold at a different price from the expected one.

Popular stocks such as NVIDIA Corporation usually have high liquidity, which helps reduce slippage. However, slippage can still happen during periods of heavy market activity.

It is more likely:

• Right after the market opens
• Before the market closes
• During earnings announcements
• During highly volatile conditions

Calmer trading periods generally have a lower risk of slippage.

How Market Structure Affects Slippage

The Role of Algorithmic Trading

Automated trading systems can increase slippage because they:

• Execute trades within milliseconds
• React instantly to news
• Quickly change supply and demand
• Create temporary liquidity that disappears rapidly

The Role of Market Makers

Market makers help provide liquidity by continuously offering buy and sell prices.

They can reduce slippage by:

• Increasing liquidity
• Filling orders faster
• Supporting large trades

But during volatile markets they may:

• Widen spreads
• Increase trading costs
• Cause larger slippage

Dealing Desk vs No Dealing Desk Brokers

Your broker’s execution model can affect:

• Slippage
• Execution speed
• Spreads
• Order quality

Dealing Desk Brokers (Market Makers)

• Handle trades internally
• Often offer fixed spreads
• May requote prices during volatility
• Can experience slower execution in fast markets

No Dealing Desk Brokers (ECN/STP)

• Send trades directly to liquidity providers
• Usually offer faster execution
• Often provide tighter spreads
• Preferred by scalpers and short-term traders

How Brokers Affect Slippage

• Faster execution can reduce slippage
• Better liquidity usually improves order fills
• Slow execution may increase slippage during volatility

What Is Slippage Tolerance?

Slippage tolerance is a setting on some trading platforms that allows traders to decide how much slippage they are willing to accept before an order is canceled.

This is especially useful in:

• Crypto trading
• Highly volatile markets
• Automated trading systems

However, traders still need to monitor their orders carefully because partial fills and canceled orders can still happen.

Slippage During Market Gaps

What is slippage in trading during market gaps? This is one of the most dangerous forms of slippage traders can experience.

Slippage becomes more dangerous during market gaps.

This commonly happens:

• Over weekends
• After major news
• During earnings releases
• During geopolitical events

Example:

• Stop loss placed at 1.1000
• Market opens at 1.0950
• Trade closes at the next available price

This can lead to larger-than-expected losses.

Why Scalpers Care More About Slippage

Scalpers target very small price movements, so even tiny slippage can heavily affect profits.

Why it matters:

• Small price differences impact results more
• Slippage can ruin short-term trades
• Fast execution is extremely important
• Tight spreads and strong liquidity matter more

Scalpers usually prefer:

• Fast brokers
• VPS hosting
• Low latency execution
• High liquidity markets

The Psychological Impact of Slippage

Repeated slippage can affect trader emotions and decision-making.

It may cause:

• Frustration
• Revenge trading
• Fear during volatility
• Emotional trading decisions
• Breaking trading plans

Understanding what is slippage in trading also means understanding how it can psychologically affect traders during volatile markets.

Slippage vs Spread vs Commission

Many beginners confuse these trading costs.

Simple Example:

A trade may include:

• Spread cost
• Broker commission
• Slippage during execution

All three together affect the total trading cost.

How to Reduce Slippage?

Use Limit Orders

A limit order only executes at your chosen price or better.

This gives traders more control compared to market orders.

Avoid Major News Events

High-impact news events create strong volatility.

Avoid trading during:

• FOMC meetings
• CPI and inflation reports
• NFP releases
• Earnings announcements

Trade Highly Liquid Markets

Higher liquidity usually means:

• Faster execution
• Smaller spreads
• Less slippage

Best Forex Trading Times

Avoid Low-Liquidity Hours

The risk of slippage increases during:

• Late-night sessions
• Holidays
• Weekends
• Market openings after gaps

Use a VPS (Virtual Private Server)

A VPS helps traders:

• Maintain stable internet connection
• Reduce execution delays
• Improve speed for automated trading

Especially useful for:

• Scalping
• Expert Advisors (EAs)
• High-frequency trading

Best Markets for Low Slippage

General Rule:

• High liquidity = lower slippage
• Low liquidity = higher slippage
