## Flash Crash Forensics

Flash crash forensics is the systematic investigation into the sudden, sharp, and short-lived price drops that occur in financial markets, particularly those driven by automated trading and high leverage. By analyzing order flow, execution logs, and protocol state changes during the event, investigators aim to determine if the crash was triggered by fundamental news, a technical glitch, or deliberate market manipulation.

In the crypto domain, these events are often amplified by the liquidation of over-leveraged positions, which creates a cascading effect that pushes prices further down. Forensic analysis identifies the specific sequence of events, such as the initial large sell order that depleted liquidity, and how market participants reacted.

This knowledge is vital for improving market resilience and designing better circuit breakers for future volatility events.
