Well, so far I've been right.

It looks like a tapering triangle. I think it's pretty clear that the red grid will not be able to help us. Okay, I'm removing the red Fibonacci grid. Perhaps the levels of waves (3) and (A) will be related by Fibonacci. Let's use the level of wave (3) as a basis for measuring the value of a possible reduction. I paint blue grid on the chart. Since it is difficult to predict the structure of reduction, Fibonacci levels play an important role in determining the possible point of completion the wave (A). In order to find completion of reduction, we have to see on the chart combination of five waves that could fit in the Fibonacci grid.
