# 🔄 Data Aggregation and Reliability

QIE Oracle aggregates price data from **multiple trusted sources** for each supported asset.

* Outliers and anomalous values are automatically detected and **filtered out**.
* This **redundancy** minimizes the risk of incorrect or manipulated data from any single source affecting on-chain price feeds.

By combining data streams, QIE Oracle ensures **robustness and accuracy** for all consumers of its price feeds.
