Batch Modify Order Channel

Description

This channel uses a two-tier status code structure:

Outer code / msg: whether the batch order modification request as a whole was accepted
Inner args[i].code / args[i].msg: the modification result of each individual order

An outer code=0 does not mean every sub-order succeeded.

The ACK response only indicates that the request has been successfully accepted. Please use the WebSocket order push channel to confirm the actual status of each order.

Isolated margin mode is not supported for batch order modification.
