Lesson 37 - Why did we break up?

This is a question from Setup and Training material of Weis Wave with Speed Index. You need to be an owner of Weis Wave with Speed Index to view it and answer it on the group but you can answer it in this post if you wish.

The question:

By reading the waves-speed index and without considering the signals of that huge messy range in the yellow rectangle can you figure out why did we break upwards?

Enjoy!
