## Flash Crash Probability

Flash Crash Probability estimates the likelihood of a sudden, severe, and temporary drop in an asset's price. These events are often triggered by automated trading algorithms reacting to a lack of liquidity or a sudden shift in market conditions.

By analyzing order book thinness, leverage levels, and the speed of information flow, risk models can calculate the vulnerability of a market to such events. Flash crashes are a major concern for market stability, as they can trigger liquidations and contagion across protocols.

Proactive monitoring of these factors is essential for managing systemic risk in digital asset markets. It is a core component of modern financial stress testing.
