 Each data feed reflects the volatility of an asset over a specific rolling window of time. For example, some data feeds provide volatility data for the last 24 hours, 7 days, and 30 days of time. You can compare the data across these windows to infer whether the volatility of an asset is trending up or down. For example, if realized volatility for the 24-hour window is higher than the 7-day window, volatility might increase.
 
-The same high-quality data providers used in Chailink’s price feeds sample price data every 10 minutes to refresh volatility estimates. onchain values are updated when the feed heartbeat or deviation threshold is met.
