Looking at daily chart
it seems we are stuck in a limited price range from many months, and we are not seeing the 200$ swings of a time. Now we are bouncing around 460 area, that is acting as a support. If this support is broken i'm looking at 420 area as a possible target. A very dangerous zone could be the 340 level,and i think it could hold very well attracting a great amount of money into the market, beginning the new uptrend phase.
If the 455 support holds and new investors come into the market i'm looking to these levels of resistance: 516, 565, 677.
Good luck for your trading
