Slippage Risk Modeling
Slippage risk modeling is the quantitative assessment of the difference between the expected price of a trade and the price at which the trade is actually executed. This discrepancy occurs due to market volatility, insufficient liquidity, or execution delays during the order routing process.
By modeling this risk, traders can estimate the potential impact of their order size on the market price before submitting it. This is particularly important for large institutional orders that could move the market against the trader.
Effective models incorporate order book dynamics, historical volatility, and the speed of execution to provide a probabilistic range of potential slippage. This allows for better risk management and the implementation of smarter execution algorithms like TWAP or VWAP.
