## Request body

- union
  - object
    - `assets` object[], required
      - `assetReturns` number[], required: assetReturns[t] is the logarithmic return of the asset at the time t
      - `assetPriceHighLowNearnessRatioSkipPeriod` integer: The number of the most recent periods excluded from the asset nearness ratio computation; must be < assetPriceHighLowNearnessRatioFormationPeriod
      - `assetPriceHighLowNearnessRatioFormationPeriod` integer, required: The look back period over which to compute the asset nearness ratio
  - object
    - `assets` object[], required
      - `assetPrices` object[], required: assetPrices[t] contains price information for the asset at the date t
        - `date` string, required: The date corresponding to the date t in format YYYY-MM-DD; all dates must be distinct
        - `close` number, required: The close price of the asset at the date t
      - `assetPriceHighLowNearnessRatioSkipPeriod` integer: The number of the most recent periods excluded from the asset nearness ratio computation; must be < assetPriceHighLowNearnessRatioFormationPeriod
      - `assetPriceHighLowNearnessRatioFormationPeriod` integer, required: The look back period over which to compute the asset nearness ratio

## Response `200`
