There's a short-term bear trend developing, which comes to a point at the long-term log . If it breaks that , I'm expecting all hell to break lose. If it breaks up, then I believe that is an indication it is ready to break resistance at 680.
Ultimately, the long-term log has been reliable support, and I see no reason why it should change now. In other words, moon.
PS - I'm still pretty new at this. How do you pick the exchange you want to use on the chart?
