Help me determine the vehicle from the screenshot

friends, i came across one zabugorny forum on one interesting screen.

I believe that the grid works and a horse depot is needed for implementation, but there are a couple of questions.

1. What is the logic laid?

2. How are micro-trends determined by which it pyramids the volume?

3. How resets position?

if you have any suggestions, i would be happy to talk about this topic.
