Latency

Definition

Latency refers to the time delay between the initiation of an action and the observable response or completion of that action within a system. In financial markets, this typically measures the time taken for market data to propagate, for an order to be transmitted and executed, or for a transaction to achieve finality. For cryptocurrency networks, latency is influenced by block propagation times and network congestion. High-frequency trading strategies are particularly sensitive to these delays.
