    - `fees_usd` number, double, required: Builder fees collected on that day, in USD
    - `fills` integer, required: Fill sides that carried one of the builder's codes
  - `days` integer, required: The window actually used, after clamping
  - `total_fees_usd` number, double, required: All-time builder fees, in USD
