闯ü谤驳别苍,

Success! And epiphany #1: when I skip setting ocaGroup (while keeping parentId as in initial order) the problem goes away. The execution engine is once again purring happily!

I appreciate your explanation of how you use openOrder(). I do use it (and the other callbacks you list) to track fills, cancellations, cross check positions etc., but it never occurred to me to look beyond .status and .totalQuantity.?
I am going to take a closer look at this as it has clear potential for debugging if nothing else. Some aspects of your PositionController have equivalents in my code, but this is a good opportunity for me to think it through again.

Thanks again, this has been most helpful.
