Order Group Request (35=UOG)
Manage order groups with Create, Reset, Delete, Trigger, and Update operations.Required Fields
Optional Fields
Order groups are scoped per subaccount. An
OrderGroupID created under AllocAccount=2 cannot be reset, updated, deleted, or triggered without also passing AllocAccount=2 on the follow-up request. If the AllocAccount value does not match the group’s owning subaccount, the exchange returns an ORDER_GROUP_NOT_FOUND business reject.Fields by Action
Create (Action=1)
The OrderGroupID is generated by the server and returned in the response. Do not include tag 20130 in Create requests.
Reset (Action=2)
Delete (Action=3)
Trigger (Action=4)
Update (Action=5)
If the updated limit would immediately trigger the group (based on the rolling 15-second window), the server cancels all
orders in the group and marks it as triggered. No new orders can be placed until the group is reset.
