Heads up - TD Ameritrade glitch today. I just called; it's a known "system wide" problem. The rep assured me they won't take any liquidation action based on the erroneous balances. This is an account where I keep $3something -- it's showing a balance of negative $9something --
Did you get the situation resolved? I have been having issues with their margin system since they do not correctly calculate spread margins anymore when you have unmatched call and put spreads (IC's). I have also had issues with bad quotes leading to false valuations. On the day the SPX dropped 111 points a few weeks back, there were serious issues all over the place with nonsense quotes.
Obviously, this broker has an issue.... https://www.consumeraffairs.com/finance/ameritrade.html http://downdetector.com/status/td-ameritrade
It corrected itself about half an hour later. This isn't the first time TD has been glitchy, but it's the most dramatic -- showing a "loss" of $13m. At those sites, only the disgruntled post reviews. In general TD is very good.
