# Compare price slippage between exchanges

Price slippage measures how liquid a market is by measuring the gap between the expected and actual price of a marker order. When markets drop and there are large sell-offs, slippage often increases and it becomes harder to buy or sell at your desired price. This varies by exchange, trading pair, and time of day. Using Kaiko's data, we can measure potential BTC slippage across exchanges for different trade sizes. This provides valuable insight for market traders looking to minimize losses.
