[Resolved]  Olymp Trade — Confusing lines on the chart, these fake?

I have been meaning to get into trading for a long time and I was desperately searching for a decent and a proper broker to suit my needs. Anyways, I landed this broker whilst I have had no idea what trading is, how it is done, how I work with a broker and whatnot. But Olymp Trade has a competitive advantage. They have tutorials, and a blog, and a help center to help you go through any kinds of process that you go through the first time. Well. I folllowed the instructions, learn about the assets and how to trade little bit and I finally deposit some money, I open up a chart. I know what a price chart should like. But there is one in the middle of the screen and there are 3 other lines with different collors at the bottom of the screen. Which one do i look at, which one do i take seriously, which one is the right one, are some of them fake? i dont even understand whats going on but perhaps they are trying to make me lose me money?
