## Impulse Response Functions

Impulse Response Functions in financial markets describe how a specific asset price or trading volume reacts over time to an unexpected shock, such as a sudden large order or a piece of breaking news. In the context of cryptocurrency and derivatives, these functions help analysts quantify the persistence of volatility and the speed at which markets return to equilibrium after a liquidity disruption.

By applying a unit shock to the system, researchers can observe the path of recovery or the potential for cascading effects across interconnected protocols. This tool is essential for understanding how order flow toxicity impacts market microstructure.

It provides a visual and mathematical representation of market resilience. Essentially, it tracks the decay of the impact of a single exogenous event on the price process.

This allows traders to differentiate between temporary noise and structural shifts in liquidity. It is a cornerstone of quantitative finance used to calibrate risk models and anticipate slippage in decentralized exchanges.

Ultimately, it measures the sensitivity of a financial system to external pressure.
