The current Mark IV is updated every minute. These metrics are then compared according to the selected "daysBack" parameter. All the differences are found in the columns with the indication "change" (current metrics vs days ago metrics) ## OpenAPI ````yaml get /analytics/volatility/metrics openapi: 3.1.0 info: title: derivatives-api version: '2' servers: - url: https://api.amberdata.com/markets/derivatives security: - sec0: [] paths: /analytics/volatility/metrics: get: summary: Volatility Metrics (24 hr) description: >- This endpoint contains all the metrics useful for having an immediate overview of the options market, for each active expiry.
