This question best explained by example

Say I submit a limit order with qty 10 and it has 2 OCO groups defined. The first group has 7 and the 2nd group has 3
SC will break this up into two separate limit entry orders

Does the first group always get submitted first and is it deterministic that it will be first in the order book queue (as it arrives first to the exchange)?
In other words, can one count on it that the first group will always be before the 2nd group in the order book queue when considering fills and partial fills?

Does your answer make a difference if the service it Teton or a 3rd party like CQG/IB/Rithmic?

We added this to the documentation:
When Attached Orders are sent to the external Trading service, they are iterated through from top to bottom as they are listed in the Attached Orders list on the Targets tab of the Trade Window. If an Attached Order has a sibling order, the corresponding Target or Stop in the same OCO Group, then as Attached Orders are processed from top to bottom in the list, the sibling order, for the currently being processed Attached Order is located in the list and these are sent at the same time.

How the orders are going to be in the queue at the exchange we do not know. And we cannot answer that question with Teton either because we do not know what happens after they are sent to the exchange.
