execId format documentation

Brocksdorff All Messages By This Member #52088 Hey folks, apparently the execId field of an order has a well defined structure. execId = AAAAAAAA.BBBBBBB.CC.DD Is there any documentation on what those numbers mean. For example DD seems to be partial fills counter. thanks
Gordon Eldest All Messages By This Member #52100 Yes it does have a well defined structure, and it look pretty stable and guess-able in part, and yes last digits are documented However it is supplied by IB as a 'string',? IMHO as I not aware of any additional documentation about it's content, I consider that IB may modify it without warning. IB only responsibility is to make it consistent as a unique string in time and across their various reporting system and API Just for sake of curiosity why do you want to know the structure ? There are various other id to help identifying the context of the execution.
[email protected] All Messages By This Member #53337 A while back I was asking IBKR api support team this question. I also could not find much about it in the documentation. ? "What is all of the information that it contains? How is it generated?" I couldn't get any information from them beyond "it's just a unique identifier, and the last two characters describe if a revision took place." ? My takeaway from that conversation was that I shouldn't' write any code that uses this string in an unsupported way (duh). ? Sorry--I don't really have a direct answer for you either.
