# Extreme outliers removal First, an average price is calculated based on the last 100 sales (without current and outliers) that were not marked as outliers.\ \ A sale is classified as an extreme outlier if the price is below 5% or 950% above the average sale price to date. For example, if the price of sale is 3 ETH but the average price to date is 100 ETH (not including the current sale), then the 3 ETH sale is removed; the 951 ETH sale would be removed in the same way. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
