## Price Aggregation Mechanisms

Price aggregation mechanisms are the mathematical methods used to combine multiple raw data points into a single, reliable price for a smart contract. These methods must be robust against outliers, noise, and deliberate manipulation.

Common approaches include calculating the median price, using volume-weighted averages, or applying time-weighted averages. By discarding extreme values, the protocol ensures that the price remains stable even if one source provides inaccurate data.

These mechanisms are a critical part of the oracle's function, acting as the final filter before data is used in financial calculations. The choice of aggregation method depends on the asset type and the desired level of responsiveness versus stability.

A more responsive aggregator might track price changes faster but be more susceptible to noise. A more stable one might be safer but could lag behind real-time market movements.

Balancing these factors is key to providing accurate and useful price feeds.
