From example below, I have no idea what figure "8.0 4" in the bottom mean.
Does it mean that it takes 4LTC to breach price 8.0 ? Then it would make no sense, as the current price already below it.
That situation is normal and quite common. The "current price" is the price of the last transaction. After that transaction occurred, new orders came in, including some bids at 8 or more -- above the last transaction.
