## Flash Crash Modeling

Flash Crash Modeling is the study of sudden, severe, and rapid price declines in digital asset markets. These events are often caused by a combination of algorithmic trading, lack of liquidity, and cascading liquidations.

By modeling these crashes, researchers can identify the systemic vulnerabilities that lead to such extreme volatility. This involves analyzing order flow data to see how sell pressure accelerates during panic states.

Understanding these dynamics helps in designing more robust market structures and risk management tools that can withstand periods of extreme market stress.
