How does Slippage in crypto work

Last Updated 2026/07/06

Definition: Slippage is the difference between the expected price of a trade and the price at which the trade actually executes.
Market Dynamics: It is primarily caused by high market volatility or low liquidity in an asset's order book.
Types: Slippage can be negative (buying higher/selling lower than expected) or positive (buying lower/selling higher).
Prevention: You can minimize slippage by using limited orders, setting a slippage tolerance, and trading during high-volume hours.

Slippage occurs when the market price of a cryptocurrency changes between the moment you submit your order and the moment it is confirmed on the blockchain or matched in an exchange's order book.

While it happens in all financial markets, it is particularly common in crypto due to the 24/7 nature of the market and the extreme volatility of certain altcoins.

How it Works (An Example)

Imagine you want to buy 1 Bitcoin (BTC) for $60,000. You click the "Buy" button, but in the few milliseconds it takes for the exchange to process your request. Several other large buy orders are filled, pushing the best available price up. By the time your order executes, you are filled at $60,050.

The $50 difference is your slippage.

High Volatility

In crypto, prices can swing several percentage points in seconds. This rapid movement is the most common cause of slippage. If the price moves while your transaction is "in flight," the original quote becomes invalid, and the system fills your order at the next best price.

Low Liquidity

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

Deep Liquidity: High-volume pairs like BTC/USDT have massive order books. Large trades can be absorbed with minimal price movement.
Thin Liquidity: Small-cap tokens often have "thin" order books. A single large market order can "sweep" through all the available sell orders at the current price, forcing the rest of the order to fill at much higher prices.

Execution Speed & Network Congestion

On decentralized exchanges (DEXs), slippage is often tied to blockchain speed. If a network is congested, your transaction may take longer to confirm. During that delay, the market price continues to move, increasing the likelihood of a price gap.

While you cannot eliminate market movement, you can use these professional tools to protect your capital:

Use Limit Orders

Unlike market orders (which prioritize speed), limit orders prioritize price. You set a specific price at which you are willing to buy or sell. If the market doesn't reach that price, your order won't fill, ensuring you never pay more than you intended.

Set a Slippage Tolerance

Most trading platforms allow you to set a "Slippage Tolerance" (usually 0.5% or 1%). If the price moves beyond this percentage, the transaction is automatically canceled.

Break Up Large Trades

If you are trading a token with low liquidity, avoid placing one massive market order. Instead, split your trade into smaller chunks over a period of time. This allows the order book to "refill" and prevents you from single-handedly driving the price against yourself.

Slippage is a natural part of the crypto ecosystem, acting as the gap between expectation and reality in a volatile market. By understanding that liquidity and volatility are the primary drivers, you can adjust your strategy—using limit orders and tolerance settings to ensure that "slipping" doesn't eat into your trading profits.

Is slippage the same as a trading fee?

No. Trading fees are a fixed percentage charged by the exchange for facilitating the trade. Slippage is a market-driven price difference that goes to the liquidity providers or other traders, not the exchange itself.

Can slippage be positive?

Yes! If you place a buy order and the price drops suddenly before execution, you may get filled at a lower price than you expected. This is called positive slippage.

Why is slippage higher on DEXs than CEXs?

Decentralized exchanges (DEXs) rely on on-chain confirmation times and automated market makers (AMMs), which can be slower than the centralized matching engines used by platforms like ours. This delay makes them more susceptible to price shifts during the transaction process.

What is a "Price Impact"?

Price impact is often confused with slippage. Price impact is the immediate change in price caused specifically by your trade size relative to the liquidity pool. Slippage is the change in price caused by general market movement while your trade is processing.
