Slippage Quantification Methods

Calculation

Slippage quantification fundamentally involves determining the difference between the expected trade price and the actual execution price, a critical metric in assessing trading costs. Accurate calculation necessitates granular market data, including order book depth and trade timestamps, to discern price impact across various execution venues. Methodologies range from simple percentage differences to more sophisticated volume-weighted average price (VWAP) comparisons, accounting for the size and timing of the trade. Realized slippage is then contrasted with predicted slippage, informing strategy optimization and risk management protocols.
