What this page answers Use this checklist to distinguish a market reference, broker-priced OTC instrument, proprietary synthetic product, or an unclear price source. Every reusable row has a stable citation ID, a permanent link, and an explicit evidence boundary.

Classification outcomes
market reference The platform identifies a recognizable market instrument and a reference source or method that can be checked for the observed session.
broker priced otc The platform identifies an off-exchange or broker-priced instrument whose quote or session is distinct from the referenced market.
proprietary synthetic The platform identifies a proprietary or derived index with its own generation, schedule, or settlement explanation.
unclear The available ticket and first-party terms do not support one of the other classifications. Use unclear when a named source, observation time, or settlement basis is missing.
Publication boundary Classify the evidence, not the instrument name Classify what a platform discloses about an instrument and settlement source without treating the instrument label as proof
Reuse the checklist Link to one observation field when documenting a gap. Preserve the exact platform label and source evidence rather than replacing an unknown field with an inference.
