Slippage is a common phenomenon in financial markets, especially in the fast-moving world of cryptocurrency trading. At its core, slippage refers to the difference between the expected price of a trade and the actual price at which the trade is executed. While it may seem like a minor detail, slippage can significantly impact your trading outcomes—especially when dealing with large volumes or highly volatile assets.
Understanding slippage empowers traders to make more informed decisions and implement strategies that reduce unwanted surprises. In this guide, we’ll break down what causes slippage, how it affects your trades, and practical steps you can take to minimize its impact.

Understanding Slippage: The Basics
Slippage occurs when there’s a delay or gap between the time you place a trade and when it gets filled by the market. This often happens because market conditions change rapidly—prices shift due to new orders, news events, or sudden spikes in trading volume.
There are three types of slippage:
- Negative slippage: You get a worse price than expected (e.g., buying higher or selling lower).
- Positive slippage: You get a better price than expected (e.g., buying cheaper or selling for more).
- No slippage: Your order fills exactly at the intended price.
While positive slippage might sound ideal, many traders prefer predictability over unexpected gains. Consistency in execution helps maintain discipline in a well-structured crypto trading strategy.
What Causes Slippage in Crypto Markets?
The primary drivers of slippage are low liquidity and high market volatility—two factors that frequently coexist in cryptocurrency markets.
Liquidity and the Order Book
Liquidity refers to how quickly an asset can be bought or sold without causing a major price movement. On exchanges, liquidity is reflected in the order book, which lists all open buy and sell orders for a given asset.
When you place a market order, the exchange matches your order with existing orders in the book. If there aren’t enough orders at your desired price level, the system automatically fills the remainder at the next best available price—this results in slippage.
For example:
- You want to buy 100 SOL at $168.19.
- Only 60 SOL are available at that price.
- The remaining 40 are filled at $168.84.
- Result: Negative slippage on part of your order.
Large trades are especially prone to this issue because they "eat through" multiple price levels in the order book.
Market Volatility
Crypto markets are known for rapid price swings. News, macroeconomic events, or whale movements can trigger sudden shifts in supply and demand. During these periods, even small delays in execution can lead to significant slippage.
Real-World Example of Slippage
Imagine you're entering a market buy order for Ethereum (ETH) during a sharp rally. The current ask price shows $3,500, so you expect to pay around that amount per coin.
However, within seconds:
- Demand surges.
- The top ask price jumps to $3,515.
- Your order executes across several tiers of the order book.
Final average fill price: $3,512 — resulting in **negative slippage of $12 per ETH**.
If you were buying just one ETH, the loss is minimal. But for a 100 ETH purchase, that’s an unexpected $1,200 added cost.
Conversely, if prices had dropped after placing the order, you might have enjoyed positive slippage, paying less than expected. But again, most professional traders prioritize control and predictability over lucky breaks.

How to Minimize Slippage
While eliminating slippage entirely isn't always possible, you can significantly reduce its frequency and severity using proven techniques.
1. Use Limit Orders Instead of Market Orders
A limit order allows you to set the maximum price you're willing to pay (for buys) or the minimum you’ll accept (for sells). Unlike market orders, which execute immediately at current prices, limit orders only fill when the market reaches your specified price.
This gives you full control—but comes with a trade-off: if the market doesn’t reach your price, your order may not execute at all.
2. Focus on High-Liquidity Assets
Trading major cryptocurrencies like Bitcoin (BTC), Ethereum (ETH), and Solana (SOL) typically results in lower slippage due to deeper order books and higher trading volumes.
Before entering any trade, check:
- 24-hour trading volume
- Order book depth
- Bid-ask spread width
These metrics help gauge how easily your order will be filled without significant price deviation.
3. Break Large Orders into Smaller Ones
Instead of placing one large market order, consider splitting it into several smaller ones executed over time. This reduces your immediate market impact and spreads out potential slippage risk.
For instance:
- Instead of buying 50 BTC at once…
- Buy 5 BTC every 10 minutes during high-volume periods.
This method requires patience but often leads to better average prices.
4. Trade During Peak Market Hours
Liquidity varies throughout the day. Trading during peak activity—such as when U.S., European, and Asian markets overlap—increases the chances of finding matching orders at favorable prices.
Many platforms offer real-time volume tracking tools to help identify optimal trading windows.
Frequently Asked Questions (FAQs)
Q: Is slippage unique to crypto trading?
A: No. Slippage occurs in all financial markets—including stocks and forex—but it's more pronounced in crypto due to higher volatility and fragmented liquidity across exchanges.
Q: Can I completely avoid slippage?
A: Not entirely. Even with limit orders, network congestion (especially on decentralized exchanges) can cause execution delays. However, smart planning and tool usage can reduce exposure dramatically.
Q: Does slippage only happen on centralized exchanges?
A: No. Decentralized exchanges (DEXs) often experience higher slippage due to reliance on automated market makers (AMMs) and variable liquidity pools. Slippage tolerance settings are commonly used on DEXs to prevent extreme deviations.
Q: How do I set slippage tolerance on trading platforms?
A: Most platforms allow you to define a slippage threshold (e.g., 0.5%, 1%). If the price moves beyond that range during execution, the trade won’t go through—or will partially fill depending on settings.
Q: Is positive slippage beneficial?
A: Yes, but it's unpredictable. While getting a better price improves returns, relying on positive slippage isn’t a sustainable strategy. Consistent execution via limit orders is preferred.

Final Thoughts
Slippage is an unavoidable aspect of crypto trading—but understanding it turns it from a hidden cost into a manageable variable. Whether you're a day trader or a long-term investor, being aware of liquidity, order types, and market timing can make a meaningful difference in your results.
By focusing on high-volume assets, using limit orders wisely, and avoiding trades during low-liquidity periods, you gain greater control over your entry and exit points.
Remember: successful trading isn’t just about picking winners—it’s about optimizing every part of the process, including how your orders are executed.
