Lets take a closer look at wave (c) of the triangle. As you know, each leg in a triangle is corrective that means it has a three wave structure (abc). The fist part seems to be some kind of wedge shape (diagonal) for the first wave a and then we get a deep wave b correction. The final c wave is a normal five wave impulse. The macd shows the wave 3 position (deepest) and you can see a big bullish divergence between 3 and 5. The spike seems to indicate the end of 5 because it overlapped with wave one giving us a hint that this is the start of wave (d) up. Also note the well balanced relation between wave a and c (c=a*1.618)
