Price insight

Hey guys, how exactly the price insight works? I just bought one, I can see the circular graphic, I don’t exactly know what they mean, but I went to several solar systems, but nothing changes on the market, the prices is the same on every solar system, what I’m doing wrong? Please help me since the effect expires in one day.

It’s currently useless, as the prices always stay at -10%. They’re planned to fluctuate in the future, and then you will be able to see what the prices are in each constellation you explored (high or low).

So those graphics don’t mean anything? And will I get my wasted keys back in the next update?
