资源简介：
LOB is divided in 10 levels, where each level consists of four columns. These four columns refer to the ask price and volume and the bid price and volume, respectively. The best level is Level 1. It contains the best Ask price which is the minimum price that a seller is willing to accept for a share of stock and the best Bid price which is the maximum price that a buyer is willing to pay for a share of stock. Next to Level 1 is Level 2 and so on, up to Level 10 with the same formation but with worst Ask and Bid prices.
