When placing a cryptocurrency trade, you may notice that the final execution price is slightly different from the price you saw before submitting your order. This difference is known as Slippage.

Slippage is a normal part of financial markets and can occur in both rising and falling markets. It is especially important to understand when using Market Orders, trading large amounts, or trading cryptocurrencies with lower liquidity.

In this guide, you'll learn what Slippage is, why it happens, how it relates to liquidity and volatility, and what you can do to manage its potential impact when trading on PLUBIT Exchange.

What Is Slippage?

Slippage is the difference between the expected price of a trade and the actual price at which the trade is executed.

For example, suppose Bitcoin is displayed at:

100,000 USDT

You place a Market Buy Order expecting to purchase BTC around that price.

Because market prices are constantly changing, your order may actually be executed at an average price of:

100,050 USDT

The difference between the expected price and the actual execution price is called Slippage.

Slippage can be:

• Positive, when you receive a better price than expected.
• Negative, when you receive a less favorable price than expected.

Why Does Slippage Happen?

Slippage occurs because cryptocurrency markets are constantly changing.

Several factors can contribute to slippage.

Market Movement

Prices can change between the moment you submit an order and when it is executed.

This is particularly common during rapidly moving markets.

Liquidity

Liquidity refers to how easily an asset can be bought or sold without significantly affecting its price.

Highly liquid markets generally have more orders available near the current market price, which can reduce potential slippage.

Less-liquid markets may have fewer orders available, increasing the potential for price differences.

Order Size

Large orders can consume multiple levels of the Order Book.

For example, if there are only a limited number of BTC available at 100,000 USDT, a large Market Buy Order may continue matching against sell orders at:

• 100,000 USDT
• 100,050 USDT
• 100,100 USDT
• 100,200 USDT

As a result, the final average execution price may be higher than the initial displayed price.

Market Volatility

Rapid price movements can increase the likelihood of slippage.

During highly volatile conditions, prices can change significantly within seconds.

Slippage and the Order Book

The Order Book contains active buy and sell orders at different price levels.

When you place a Market Order, your order is matched against available orders in the Order Book.

For example:

Sell Price : 100,000 USDT

Available BTC : 0.10 BTC

Sell Price : 100,050 USDT

Available BTC : 0.20 BTC

Sell Price : 100,100 USDT

Available BTC : 0.30 BTC

Sell Price : 100,200 USDT

Available BTC : 0.50 BTC

If you place a Market Buy Order larger than the amount available at 100,000 USDT, the remaining portion may be matched at higher prices.

This can result in a higher average execution price.

Example of Slippage

Suppose you want to buy 1 BTC.

The Order Book contains:

• 0.2 BTC at 100,000 USDT
• 0.3 BTC at 100,100 USDT
• 0.5 BTC at 100,200 USDT

Your Market Buy Order is large enough to purchase the entire 1 BTC.

Your order may therefore be filled across multiple price levels instead of being executed entirely at 100,000 USDT.

The final average execution price will reflect all matched orders.

This is an example of how Order Book depth can influence Slippage.

Positive vs Negative Slippage

Slippage isn't always unfavorable.

Negative Slippage

Negative Slippage occurs when your trade executes at a less favorable price than expected.

For a Buy Order:

Expected Price:

100,000 USDT

Actual Price:

100,100 USDT

The execution price is higher than expected.

Positive Slippage

Positive Slippage occurs when your trade executes at a better price than expected.

For a Buy Order:

Expected Price:

100,000 USDT

Actual Price:

99,950 USDT

The execution price is lower than expected.

Which Orders Are Most Affected by Slippage?

Market Orders

Market Orders are generally more exposed to Slippage because they prioritize execution rather than a specific price.

The order is matched against available liquidity in the Order Book.

Limit Orders

Limit Orders provide greater price control because you specify the maximum price you're willing to pay or the minimum price you're willing to accept.

However, a Limit Order may remain unfilled if the market does not reach your selected price.

Slippage vs Spread

Slippage and the Bid-Ask Spread are related but different concepts.

Bid-Ask Spread

The difference between:

• Highest Bid Price
• Lowest Ask Price

Slippage

The difference between the expected execution price and the actual execution price.

A market may have a narrow spread but still experience slippage if a large order consumes multiple price levels.

Slippage vs Volatility

Volatility and Slippage are also different.

Volatility

Measures how quickly and significantly an asset's price changes.

Slippage

Measures the difference between the expected and actual execution price.

High volatility can increase the likelihood of slippage because prices can move rapidly while an order is being executed.

Slippage vs Liquidity

Liquidity plays an important role in determining potential slippage.

High Liquidity

More orders are generally available near the current price.

This can help reduce potential price impact.

Low Liquidity

Fewer orders may be available.

A large order can therefore move through multiple price levels, increasing potential slippage.

How to Reduce Potential Slippage

Slippage cannot always be completely avoided, but you can take steps to manage its potential impact.

Trade More Liquid Markets

Popular trading pairs generally have more active buyers and sellers.

Use Smaller Orders

Smaller orders are less likely to consume multiple levels of the Order Book.

Use Limit Orders

Limit Orders allow you to specify your preferred execution price.

However, there is a trade-off: your order may not execute.

Check the Order Book

Review the available liquidity before placing a large Market Order.

Look for:

• Order depth.
• Bid-Ask Spread.
• Available quantities.
• Price levels.

Avoid Extreme Volatility

During major market movements, prices can change rapidly.

Waiting for market conditions to stabilize may help reduce potential execution differences.

Why Slippage Matters

Understanding Slippage is important because it directly affects the final result of your trade.

For small trades in highly liquid markets, the difference may be minimal.

For larger trades or trades in less-liquid markets, the impact can be more significant.

Understanding Slippage can help you:

• Estimate potential trading costs.
• Choose appropriate order types.
• Evaluate market liquidity.
• Better understand execution prices.
• Make more informed trading decisions.

Tips for Beginners

If you're new to cryptocurrency trading:

• Understand how Market Orders work before using them.
• Check the Order Book before placing large trades.
• Pay attention to liquidity and trading volume.
• Consider Limit Orders when price control is important.
• Avoid placing large orders during extreme volatility.
• Always review the final execution price after your trade.

Frequently Asked Questions (FAQ)

1. Is Slippage a trading fee?

No.

Slippage is not a trading fee. It is the difference between the expected execution price and the actual execution price.

Trading fees are separate charges applied according to the applicable fee schedule.

2. Can Slippage happen with Market Orders?

Yes.

Market Orders are more likely to experience Slippage because they prioritize execution at available market prices rather than guaranteeing a specific price.

3. Can Limit Orders prevent Slippage?

Limit Orders provide greater price control because they specify the price at which an order can execute.

However, they do not guarantee execution. The order may remain open if the market does not reach the specified price.

4. Is Slippage always negative?

No.

Slippage can be positive or negative depending on how the market moves during execution.

5. Does higher liquidity reduce Slippage?

Generally, yes.

Markets with deeper liquidity usually have more orders available near the current market price, which can reduce potential price impact.

Common Myths About Slippage

Myth: Slippage means the exchange charged an extra fee.

Fact: Slippage is not a trading fee. It is the difference between the expected execution price and the actual execution price. Trading fees are calculated separately.

Myth: Slippage only happens when cryptocurrency prices fall.

Fact: Slippage can occur in both rising and falling markets. It depends on market movement, liquidity, order size, and available orders.

Myth: Small trades can never experience Slippage.

Fact: Even small orders can experience some slippage, especially in volatile or low-liquidity markets.

Myth: Limit Orders always execute immediately.

Fact: Limit Orders may remain open until the market reaches the specified price. Greater price control comes with the possibility of delayed or no execution.
