Does Slippage Only Occur on Market Orders, or Can It Affect Limit Orders as Well?

Slippage is primarily associated with market orders, as they demand immediate execution at the prevailing price, which can move. However, a limit order can experience a form of "opportunity cost slippage" if the market price moves away from the limit price before it can be filled, meaning the trader missed a chance for a better execution.

Real price slippage on a limit order is rare, typically only in extreme volatility or system errors.
