That's true. I've my stop at 666.40 I remember last time it retraced fast from 666 to 659. See if it can break that resistence or that trendline today.
Covered at 665.30. WIll try to short again at 666 if won't break it. The TAs are at the bottom and ready to go up.
R2 and 663.7 shall serve some support here, it could be brutal battle: http://tinypic.com/view/?pic=fjn3uv
One could make many trades around 663.70. Buy at 663.30 or lower (now) and sell at 663.80, or short above it and cover below it.
