Order Book Recovery

Algorithm

Order Book Recovery represents a suite of computational procedures designed to reconstitute a functional limit order book following a disruptive event, such as a flash crash or exchange malfunction. These algorithms prioritize price discovery and liquidity restoration, often employing techniques like midpoint pinning or simulated order flow to approximate pre-disruption market conditions. Successful implementation requires careful calibration of parameters governing order placement and cancellation rates, balancing speed of recovery with the potential for introducing further instability. The efficacy of these algorithms is increasingly evaluated through backtesting and real-time monitoring of key market metrics, including spread and depth.
