What Is Slippage in Crypto Trading?

Slippage refers to the difference between the expected price of a trade and the actual price at which the trade is executed. It occurs when market conditions change between the time an order is placed and when it is filled. Slippage is common in fast-moving or low-liquidity markets and can affect both buy and sell orders.

In crypto trading, slippage can be either positive or negative, depending on whether the final execution price is better or worse than expected.

Why Does Slippage Occur?

Slippage occurs when there is not enough liquidity available at a trader’s intended price or when prices move quickly during execution. When a market order is submitted, the exchange fills it using the best available prices in the order book. If the order size is larger than the liquidity available at the top price level, the trade is completed across multiple price levels.

For instance, a trader may place a market order expecting to buy a token at $10. If only part of the order can be filled at $10 and the remaining quantity is executed at $10.10, the final average price becomes higher than expected. The difference between the expected price and the actual execution price is known as slippage.

Key Factors That Influence Slippage

• Market Liquidity: Markets with low trading volume tend to experience higher slippage because fewer orders are available at each price level.
• Order Size: Large orders are more likely to cause slippage since they may consume multiple price levels in the order book.
• Market Volatility: Rapid price movements increase the likelihood that prices will change before an order is fully executed.
• Order Type: Market orders are more exposed to slippage, while limit orders allow traders to control the maximum or minimum execution price.

Slippage in Crypto Trading

Slippage is especially relevant in cryptocurrency markets due to varying liquidity across trading pairs and exchanges. It is commonly observed during periods of high volatility, major news events, or when trading newly listed or low-cap assets.

On exchanges that use order books, such as CoinEx, slippage depends heavily on order depth and market activity. In decentralized exchanges, slippage is also influenced by liquidity pool size and pricing mechanisms.

Slippage vs Price Impact

Slippage is often confused with price impact, but they are not the same. Slippage refers to the difference between the expected and executed price, while price impact measures how much a trade itself moves the market price. Large trades can increase both slippage and price impact, especially in illiquid markets.

Why Does Slippage Matter?

Slippage directly affects trading outcomes and execution costs. Understanding slippage helps traders choose appropriate order types, assess market liquidity, and avoid unfavorable trade execution during volatile conditions.
