After you call placeOrder() for an order (or in the bracket case call it once for each of the three orders), IBKR keeps your client aware of the order progress through a variety of callbacks: openOrder(), orderStatus(), execDetails(), commissionReport(), possibly error().
The openOrder() callback provides you with an Order object that reflects all the information, IBKR has about the order. The Order object you receive in the first openOrder() callback after placeOrder(), for example, has fields such as clientId, accountId, permId, ocaGroup, ... initialized by IBKR. As the order progresses, subsequent openOrder() callbacks provide Order objects that reflect whatever change took place since the last call (quantity changes due to partial fill, trigger price changes for TRAIL orders, ....)
My framework instantiates (among others) a PositionController for each instrument the client places orders for. That controller:
- makes order objects and initializes the least number of required fields when an order is initially placed (what you see as "The original bracket order" in my post)
- receives all callbacks related to the order and monitors the order progress
- maintains copies of the updated and changed Order objects it receives from time to time from IBKR )what you see in "The Profit Taker order as updated by and received from IBKR")
When it is time to make a change to an already open order (in our case the Profit Taker order), my client simply makes a call such as changeLimitPrice(). IN that case, PositionController makes a copy of the last Order object it received through openOrder(), adjusts in the copy whatever needs to be changed (in our case the limit price) and calls placeOrder() with that order object.
That approach has the advantage that I never really have to worry about what IBKR needs initialized in order for order changes to work.
Hope that makes it more clear.

Pardon my ignorance, but when you say
'The Profit Taker order as updated by and received from IBKR'
how do you receive and examine the updated order details?
?
