JSON-encoded objective function that defines the scoring formula for ranking bonds.
Contains a list of weighted terms, each referencing a field or an arithmetic expression.
Example: {"terms": [{"term": {"type": "field", "field": "duration", "factor": 0.01}, "factor": 1.0}]}

Two-letter state code of the investor's state of residence.
Example: "CA", "NY", "TX". Used only under the us_taxable
profile (drives per-bond state-tax exemptions); ignored under
custom_taxable/uk_taxable.

The risk group ID to filter for tradable inventory. If left null,
and a single risk group exists for the organization, it will be
used as the default risk group. If left null, and more than one
risk group exists, the request will fail.

Specify a side for inventory filters. Possible values:

• 'buy' will limit the results to bonds that have quotes to buy
  the instrument.
• 'sell' will limit the results to bonds that have quotes to sell
  the instrument.
• 'both' will limit the results to bonds that have quotes on both
  sides of the market, i.e. at least one quote to buy and one to sell.

Important note: If you are building a UI that leverages this API, you should be
especially cognizant that this value represents inventory side, not trade side.

A client who wants to purchase a bond will look for asks/offers where the
counterparty wants to sell. Hence, they should pass 'sell' to the API.

A client who wants to sell a bond will look for bids where the counterparty
wants to buy. Hence, they should pass 'buy' to the API.

Tax profile classification controlling how post-tax yield fields
and the post-tax objective term are computed.

• us_taxable (default): post-tax yield is the pre-tax yield
  multiplied by (1 - effective_tax_rate), where
  effective_tax_rate is the per-bond combination of
  federal_tax_rate + state_tax_rate + residing_state with
  treasury, US-territory, state-exempt-agency, and muni
  federal/state exemption carve-outs applied per bond. Capital
  gains is not applied under this profile (deferred until a real
  US capgain field is defined).
• custom_taxable: post-tax yield is the bivariate Taylor
  expansion of after-tax YTW evaluated at constants
  (s = custom_income_tax, g = custom_capital_gains_tax).
  Federal/state/residing-state are ignored.
• uk_taxable: same Taylor expansion as custom_taxable
  (using custom_income_tax and custom_capital_gains_tax), but
  the capital-gains rate is forced to 0 for instruments exempt from
  UK capital gains tax — Gilts (ice_sector_1 = Sovereign and
  currency = GBP) and QCBs (qcb_indicator = true). Income tax
  still applies to exempt instruments.
• non_taxable: no tax is applied to any instrument. Post-tax yield
  equals the pre-tax yield and tax-equivalent yield receives no
  gross-up. All rate fields are ignored.

Filtering by trade_size will only return asks and bids that
would completely fill an order of the specified quantity. More
specifically, it will return quotes where the minimum quantity is
less than or equal to the specified trade_size and the total
quantity is greater than or equal to the specified trade_size.
Optionally, set value to "lowest" to get all the quotes sorted from
least to greatest min_quantity.
