Slippage Modeling
Slippage modeling involves calculating the expected price impact of a trade based on the current depth and liquidity of an order book or pool. As order sizes increase, they consume available liquidity at better prices, forcing the execution to move further down the order book.
This results in an average execution price that is worse than the mid-market price. Slippage modeling is crucial for traders to estimate transaction costs and for protocol designers to set limits on trade sizes.
It is also used to evaluate the resilience of a market, as high slippage in normal conditions indicates a fragile liquidity environment. Accurate models must account for both static order book data and dynamic market conditions, such as sudden spikes in volatility.
