That’s like a guy bringing a car to a repair shop and saying “something is wrong with my car, did this happen to anyone else?”. “Yeah, happens to everyone who comes here.” - the car mechanic answers, “Now please tell me what your actual problem is” And until now we still don’t know whether 10 different guys having negative margin have the same exact problem that is nothing to worry about, or whether someone has a problem that he/she should worry about. So how do we know that everyone in the world who has negative margin/liquidity/balance today, has nothing to worry about? Wouldn’t you need to see more details to determine that? While it is also possible that my answer was wrong, I’m just used to describing problems with more details, and assumed that this problem may be more unique.
I see something similar here. I use two account numbers. One for trading futures. Here everything seems to be okay. The other account is used for trading ETFs. All ETFs have no bid and ask price listed and the total account value is at zero, which is obviously not correct. I assume that this will be resolved once bid/ask prices come available for these ETFs.
Updates to IB have showed my positions on Friday Night being worthless. Nothing ever happened if this is what is happening to you.
