We deploy dedicated NFT oracles on demand with custom list of collections and a variety of available data points, find out more on how to request a custom oracle:
DIA offers outlier detection and cleansing methodology for NFT floor price determination. For this, we use Interquartile Range Filter.
The Interquartile Range filter in DIA examines all trades in a trades block (e.g. Daily NFT floor price for 30 days window) and sorts them by their recorded price.
After that, this range of prices is divided into four price blocks, the Quartiles. The boundaries of the full price range also determine the boundaries of the first and the last quartile.
To clear out outliers, any trades falling into the first or the last quartile are filtered out and subsequently, only trades falling into the "middle" quartiles are returned to the caller.
