Limit Order Book Resilience
Limit Order Book Resilience measures how quickly and effectively a market's order book recovers its depth after a large trade or a sudden shock. A resilient book shows a rapid replenishment of orders at various price levels, indicating a healthy and active ecosystem of participants.
When resilience is low, a single large order can create a void in the book, leading to extreme price swings and cascading liquidations. This concept is vital for evaluating the stability of exchange protocols and the effectiveness of their market-making incentives.
Resilience analysis considers the time taken for orders to return to equilibrium and the volume density that accumulates post-disturbance. It serves as a key indicator for assessing the robustness of an exchange against structural failure or market manipulation.
