## Data Latency and Refresh Rates

Data latency and refresh rates refer to the speed and frequency at which an oracle updates the price data it provides to a smart contract. In fast-moving markets, even a few seconds of delay can be the difference between a successful liquidation and a massive loss for the protocol.

High latency means the smart contract is operating on outdated information, which is a major security risk. Protocols must balance the cost of frequent updates with the need for real-time accuracy.

Advanced oracles use trigger-based updates to ensure that prices are updated whenever the market moves significantly. Managing this latency is a key challenge in maintaining the integrity of automated lending systems.
