Market Event Latency

Definition

Market event latency denotes the temporal delta between the occurrence of a price-moving catalyst, such as a derivative liquidation or funding rate adjustment, and the reflection of that information within a specific trading venue. This interval is critical for arbitrageurs and market makers, as it dictates the window during which price discrepancies persist across disparate exchanges or order books. High levels of event latency frequently impede execution quality, leading to adverse selection risks when quoting or hedging options positions in volatile crypto environments.
