What Is the Difference between Positive and Negative Slippage?

Negative slippage occurs when a buy order is filled at a higher price than expected, or a sell order is filled at a lower price than expected, resulting in a worse outcome for the trader. Positive slippage is the opposite: a buy order is filled at a lower price or a sell order at a higher price, resulting in a better outcome.

Both are a result of market movement between the time the order is placed and executed.
