Algorithmic Scar

Consequence

An algorithmic scar refers to the lingering market distortion or behavioral pattern imprinted on an order book following a high-frequency trading error or automated liquidity withdrawal. This phenomenon emerges when rapid, machine-driven sell-offs breach critical support levels, forcing manual participants to internalize the resulting volatility long after the initial event concludes. Traders often observe these gaps as permanent shifts in liquidity depth, where the memory of the automated flash crash influences future quoting spreads and risk appetite.
