About these bars going up and down (if there are any at the moment). They show market depth changes over the last 10 minutes. The value axis for them is on the right [BTC]. Bars on the left of the current price are bid offer changes, and on the right ask offer changes. So if somebody is adding a bid offer, you will see a green bar up on the left. About colors: if bids are added they are in green, and when removed they are in red. For asks it's the opposite. That's because when somebody is adding an ask, it makes it harder for the price to go up (red). If somebody is removing an ask it's easier for the price to go up (green). Still confused? Try this
