Here I've used trend based fib extensions to try and find a pattern for the top of each cycle, as mentioned in the chart, when we have had an overshoot of the 0.50 or 50% extension and a good pullback the 5th wave has at least met the 75% extension and overshot it, when we had a weaker wave 3 with a smaller pullback we didnt reach the 75% extension.
This time we have flown past the 50% extension with wave 3 and had a decent pullback so i would expect us to at least hit the 75% extension with the probability of overshooting quite high, although not as much as in 2013 as wave 4's correction was not as severe.
