They'll get canceled after a flash-crash. Anything outside of -15% is unlikely to survive, which is about $6.80 right now.
But the premise of having a trolling GTC is a good idea -- I got an order filled on May 6 in the mid-$4 range. I've bought for less, but that's my favorite trade to date.
EDIT: Of course, if it's an ARIA-specific bear raid, then you get to keep all your trades and look like a genius!
