Price impact and price slippage are two common terms used to describe the outcome of a change in price when swapping cryptocurrency.
It is important to note that these terms do not mean the same thing.
Price impact is the change in token price caused by your own trade. Price impact is the difference between the current market price and how your trade impacts the total liquidity in a pool.
Price slippage is the difference between the price you expect to receive after swapping and what you actually receive after the swap is complete.
