Here, we not only concentrate the orders on best bid/ask queue, but also measure the orders on all different price levels. If one of two sides was more efficient for providing “service” higher execution speed for incoming limit orders, then order books of that side will induce more “customers” limit orders to arrive at this line more frequently. With time elapsing, the denominator or is getting larger and larger making the “service rate” for further incoming limit orders lower and lower. At last, the queuing system will rebalance to a new state, in which the OEI gets balanced, presented with its absolute value shrinking. Then, prices change contributed by orders’ ED and OEI of order books measured from a time dimension will cease.

This is why investment managers choose to execute portions of their big trades in the dark. When executing the large order, the mutual fund will try to not tip their hand and reveal—to opposing traders—that they are in the process of selling a large amount of stock. If other traders know that a fund is selling a big block of shares they will lower their bids—ultimately forcing the fund to sell for lower prices, reducing investment returns. We are more reasonable than the larger stock exchanges and can save issuers significant sums on both listing and on-going administrative costs.

It’s a great tool to see where the supply and demand levels are. A limit order book is a record of outstanding limit orders, which are buy and sell orders that are to be executed at pre-specified prices or better. While this extra information may not be very significant to the average investor, it may be useful to day traders and experienced market professionals who rely on the order book to make trading decisions. The presence of dark pools reduces the utility of the order book to some extent since there is no way of knowing whether the orders shown on the book are representative of true supply and demand for the stock. Order books are used by almost every exchange to list the orders for different assets like stocks, bonds, and currencies — even cryptocurrencies like Bitcoin.

The moving direction and altitude of prices in financial markets result from the interaction of buy and sell orders through a complex dynamic process. The availability of high-frequency records of orders, trades, and quotes has reported statistical regularities in limit order book data from a wide variety of different markets. LOBs are subject to frequent shocks in order flow that cause them to display nonstationary behavior, thus, in the result cause price impact. Ellul et al. reported a positive correlation between higher midprice realized volatility and the percentage of arriving orders that were limit orders. The intuition behind price moving is an imbalance between supply and demand order flows. Cont et al. show that, over short time intervals, price changes are mainly driven by the order flow imbalance , defined as the imbalance between supply and demand at the best bid and ask prices. But the state space of order book is very large conditioning on the fact that the most recent event is still problematic.
