Something to keep in mind.
Nice! I predicted the same with the MACD lines crossing just a few days ago. I could see we were close to the same cross (look at the second cross on your chart that begins about Sep). I believe my chart shows the crossing happens mid-Sep (or Oct) 2013 and our progress being the 10x upward trend through the end of the year. I have very high confidence, even after this slight crash, because the long-term trends look spectacular if you consider that history repeats itself.
