The Link ID is unrelated to the sibling relationship (target and stop order). Documentation: Link ID: An Attached Order that is in the All Groups OCO Group or a parent order, will be split into smaller orders if there is more than one OCO group used in the list of Attached Orders submitted with an order. When an order is split into smaller orders, they are linked together and this indicates the Internal Order ID used for linking. It is the Internal Order ID of the first order in that group. When one of the orders in a group of orders linked together is modified or canceled, the other ones will be as well. This happens automatically.
Canceling individually an attached Limit order will not cause the sibling stop order to be canceled. The same with the attached stop order.
