That's an outstanding question ralfito. I'll try to go more in depth with an answer this evening. For now, I recreated a chart. The time period on this chart begins in Jun 09 and ends Apr 10. This would be a good chart to study and look for some clues leading up to this massive climb.
EDIT: I remember what it was now. See that long tail in December that bottomed at .16? That's why I started posting on DUNR. It was approaching that point.
The chart on top ends in April, the chart below is the current daily chart.
Let's make one thing perfectly clear. I've made nearly 453 mistakes in my life. It's entirely possible that this post is 454.
