Price Impact Function
A price impact function is a mathematical model used to estimate how much a specific trade size will change the price of an asset. These functions are based on empirical observations of order flow and market microstructure, often accounting for variables like current volatility, asset liquidity, and the speed of execution.
By utilizing these functions, traders can forecast the expected market impact of their orders and adjust their execution strategies accordingly. These models are fundamental in quantitative finance for building optimal trading schedules that balance the need for speed against the cost of price impact.
Accurate functions are highly guarded by proprietary trading firms as they provide a significant competitive advantage.
