Requests accept 0-2 decimal places (e.g., "10", "10.0", "10.00"); responses always emit 2 decimals. Fractional contract values (e.g., "2.50") are supported; the minimum granularity is 0.01 contracts. example: '10.00' FixedPointDollars: type: string description: >- Fixed-point US dollar string. Most request fields accept 2-4 decimal places (e.g., "0.56", "0.5600"); responses emit up to 6.
