Excelent chart, only one question: where did the blue trend line came up from? It predicts the future so well...

i tried to make it parallel to the bottom area, then i thought that it would be nice if all my lines (yellow and blue) crossed on the same point. I also estimated the speed and the depth of the fall.
You can see that the angle is near from the symetrice of the downtrend yellow line (the upper one of the triangle).
For my next chart i moved the blue to support the next par of the uptrend.
