Flash Crash Resilience
Flash crash resilience is the ability of a trading system or market infrastructure to maintain orderly function during extremely rapid and severe price declines. In modern financial markets, resilience depends on the presence of circuit breakers, robust order matching engines, and the ability of liquidity providers to stay active despite overwhelming sell pressure.
Systems that lack resilience may experience system hangs, data feed delays, or total outages when order volume spikes unexpectedly. Developers must ensure that their algorithms can detect abnormal market conditions and transition into a safe mode to avoid compounding the crash.
Achieving this requires rigorous testing against historical flash crash data to ensure that execution logic remains sound when the market is at its most fragile.
