Big down day (flash crash?)

Well, that was interesting--reminiscent of 2008-9.  I traded a Gap Fill Reversal.  I got stopped out with a retrace when the Dow had a technial bounce off the first test of 25000 and might have been a little aggressive tightening my stop, but little did I know we would have a rare epic down day.  It was a 2.88R trade, so I can't kick myself that it could have been a 13R trade.
