Batch Cancel Order Channel

Description

• This endpoint allows you to cancel multiple unfilled or partially filled orders across spot, margin, and futures markets via WebSocket.
• Each request supports cancellation of up to 20 orders.
• Batch order cancellation allows partial success. Each order in the batch is processed independently — if one cancellation fails, it does not affect the cancellation of the other orders in the same batch.
• In batch order cancellation, ensure that each call uses only orderId or clientOid for identification, and avoid mixing them. If orderId and clientOid are used together in one call, clientOid will be invalid.
• Order Identification: Orders can be identified by either orderId or clientOid. When both are provided, orderId takes priority.

Note: Please check the code and msg fields for each order in the response's args list to confirm the result of each cancellation. If the result is unclear, use clientOid or orderId to query the order details.
