Limit Order Slippage

Definition

Limit order slippage represents the variance between the predetermined execution price of an order and the actual price realized upon fill, primarily occurring when liquidity at the specified level is insufficient to absorb the trade size. In high-frequency cryptocurrency environments and derivative markets, this phenomenon occurs when market depth shifts during the brief latency period between order submission and final processing. Professional traders categorize this as a friction cost that directly diminishes net returns, necessitating careful management of trade sizing relative to the order book’s visible supply.
