Error and Status Code Reference

This page summarizes the status, function, and event codes commonly used by the Fubon Neo API for futures trading, so developers can quickly look them up when troubleshooting or evaluating a status.

Order status

The current status of an order can be retrieved through GetOrderResult or received through order reports. The language-specific query methods are Python get_order_results, Node.js getOrderResults, and C# GetOrderResult.

Status	Value	Description
Pre-order	0	Pre-order
Order received by the middle office	4	Intermediate status; use GetOrderResult to retrieve the latest status.
Processing reported by the exchange	8	Exchange-reported intermediate status, often observed for orders not priced at the limit-up or limit-down price; this status is not shown by get_result or get_result_detail.
Back-office connection timeout	9	Query the status with GetOrderResult later, or contact your broker.
Order or modification succeeded	10	A new order succeeded; successful price or quantity modifications also return 10, so inspect the returned order fields to identify the modification.
Cancellation successful	30	Cancellation successful
Partially filled; remainder cancelled	40	Partially filled; the unfilled remainder was cancelled.
Fully filled	50	Fully filled
Price modification failed	19	Price modification failed
Quantity modification failed	29	Quantity modification failed
Cancellation failed	39	Cancellation failed
Failed	90	Failed

Futures and securities status-code differences

• Futures orders do not use the securities success statuses 15 and 20 for price and quantity modifications, and do not use the ACK statuses 14, 24, and 34.
• A successful futures price or quantity modification returns status 10. Inspect the price and quantity fields in that 10 result to distinguish the modification.
• Status 8 is an exchange-reported intermediate status, often observed for orders not priced at the limit-up or limit-down price. It is not included in get_result or get_result_detail results.

Function type

Indicates the operation associated with the report or query result. Values 15 and 20 in this section are function types, not successful futures order statuses.

Function	Value	Description
New order	0	New order
New-order execution	10	New-order execution
Price modification	15	Price modification
Quantity modification	20	Quantity modification
Cancellation	30	Cancellation
Failed	90	Failed
