Rejection Reasons

OrderRejectionReason

Bases: Enum

Enumeration of canonical order rejection reasons.

This enumeration defines the system-level classification of reasons for which an order request may be rejected by a broker. It provides a stable, broker-agnostic taxonomy for programmatic handling and observability of order rejections.

Value Semantics
UNKNOWN The order rejection reason could not be classified into a known category.
