Hi!

I have started with bitcoin trading with a small amount of money to see how it goes. I bought a small amount on Kraken.com (very good support there BTW!)

But these charts like the one below... how to read them?

Can someone explain what the blue and brown blocks are? What are high and low prices? And weighted average? And 24-hour volume?

Thanks in advance to this awesome community!
