Session-level rejects use `Reject (35=3)` or `Logout (35=5)`. `Text (58)` may include a pipe-delimited diagnostic value: ```text theme={null} {source}|{errorCode}|{errorMessage} ``` Treat `errorCode` as the actionable code and `errorMessage` as diagnostic text. The exact text can change without a schema change. ## Reject-code families | Range | Area | Handling guidance | | ---------------------- | --------------------------------------------------- | ------------------------------------------------------------------------------------------- | | `-100000` to `-100099` | FIX request validation | Correct the FIX message fields, identifiers, or order attributes before resubmitting. | | `-131000` to `-135999` | Order, cancel, and modify business validation | Review market state, order eligibility, duplicate identifiers, and trading rules. | | `-132000` to `-132499` | Account, quantity, price, and instrument validation | Review account status, price bands, quantity limits, instrument status, and order type. | | `-200000` to `-209999` | Order-entry rejects | Use `Text (58)` for the exact order-entry reason. | | `-210000` to `-210500` | Business-message rejects | Review message type, required fields, and application availability. | | `-220000` to `-229999` | Cancel and replace rejects | Review target order status, replace values, pending actions, and session restrictions. | | `-230000` | General order reject | Treat as a general order rejection and review `Text (58)`. | | `-420000` to `-420999` | Market and order-type constraints | Review order type, session state, price limits, quantity rules, and instrument eligibility. | | `-900000` to `-913999` | Connectivity, risk, and venue response | Review connection status, risk limits, market availability, and venue rejection text. | | Positive codes | Operational order state | Review the target order state, product status, and operational restrictions. | ##
