Wave 3 will slightly be longer than 1 or 2 or both. or Wave 5 will slightly go above Wave 3 on the breakout spot.
Should have cleared it up on chart.
You don't ever see cups form with giant peaks in the middle of them, for example. They tend to be much smoother. This pattern is almost impossible to call until the cup has fully formed. And then you start to look for the handle to form at a 33% retracement from the right side of the cup. That's when you'd start calling for the pattern.
