Seriously, I've been trading various stocks every day for the past few weeks and haven't experienced anything like I did this morning on GM! My limit orders might have had a chance to fill if placed at a few cents above my limit, like when it's trading 38.78, place the order to buy at 38.79. But even then the swings were so deep so fast, even then I question getting executed. Never seen anything like it. And on GM - go figure!
