i'm not sure how any of the above applies to me since the cancelled tickers are not even listed to begin with? i appreciate the tips although i was aware of these. well, thats a shame, bc yes, i gathered that from your earlier post, but its the exact info that i'm looking for, that you found at one time, that i can't find now. who is asking for magic or telepathy? i don't think its a crazy request for IBKR to simply suspend a potential trade if a margin issue arises. to cancel it completely and then not have a simple way to reinstate it (once a user satisfies any necessary criteria), or even reference it (after midnight) is not imo, user friendly.
