Community Approval Request #005: Volume Weighted Average Price with Interquartile Range Filter
Date: Fri, 18 February 2022
Author: DIA Core Team
Status: Approved
In this fifth Community Approval Request (CAR), the DIA DAO community will discuss, improve and approve the Volume Weighted Average Price with Interquartile Range Filter methodology, a very commonly used filter by DIA for its oracle price determination.
The VWAPIR (Volume Weighted Average Price with Interquartile Range Clearing) filter is the application of the Volume Weighted Average Price filter to data that was previously cleared by the Interquartile Range filtering system.
Filter Application
The VWAPIR filter is used in DIA’s price determination. Our API can display the latest MEDIR-120 filter values, i.e., the filter results from a 120 second interval of all recorded trades for an asset.
Implementation
The filter is implemented as part of the FiltersBlockService in this file in our Github repository
