Mutual Information between Order Book Layers

For this reason, we decided not to extend the analysis to deeper layers. However, since the work with the five stocks indicated that the significance of new layers was declining substantially by layer 5, we expect that deeper layers will behave similarly. The ability of a market to sustain a large order while avoiding a significant change in price is called the market depth, and it is considered a proxy for the liquidity of the market. Deep markets enjoy a large number and volume of orders waiting for execution in the different layers. Conceptually, market depth summarizes the state of the different layers of the limit order book and thus may act as one mechanism for the information leak we have discovered between the layers.

So, the OFI did not try to explain the latitudes of price changes. In particular, in the morning of market open, some stocks could pump and dump lots of ticks in seconds or in milliseconds in Chinese stock market. Achab et al. introduce a new nonparametric method that allows for a direct, fast, and efficient estimation of the matrix of kernel norms of a multivariate Hawkes process.

Table 1

Sirignano and Cont showed that the price movements of a given security can be predicted from the price history and order flow of other securities, suggesting that the exchanges have a role in price formation. Day traders receive the market data via their day-trading brokerage. Some forex brokers also offer Level II market data, although not all do. An imbalance is calculated for each price level, starting with the best bid and best offer. With an imbalance value of 50%, the market is in equilibrium, and traders agree with the current price. As soon as the supply/demand ratio changes and new orders are placed, the imbalance indicator automatically recalculates its values. The prime benefit of orders books is catching a glimpse of the current and near-term direction of price movement.

This happens because the price tends to move towards high liquidity levels, i.e. to the zones of limit orders accumulation to meet consent between buyers and sellers. The market is always attempting to reach for a balance market distribution to facilitate the trades between buyers and sellers. Last trade price is a fairly simple concept to understand in that it is exactly the most recent price paid for a stock as well as the number of shares in an executed trade. While this sounds simple, knowing these prices and volumes on a real-time basis can indicate broader trends about the timing and size of other trader’s positions. Motivated by the above research, we show the price impact model with a time dimension of these orders. The time dimension factor model based on Level-2 data of Chinese stock market effectively improves the R-squared compared with Cont’s model, and our theory is coherent to principles of market microstructure.

A cluster of large buy orders at a specific price may indicate a level of support, while an abundance of sell orders at or near one price may suggest an area of resistance. Order books are used by almost every exchange to list the orders for different assets like stocks, bonds, and currencies — even cryptocurrencies like Bitcoin. Although they generally contain the same information, the set up may be slightly different depending on the source. Buy and sell information may appear on the top and bottom, or on the left and right side of the screen. By visualizing liquidity, Heatmap allows a trader to get the same information the robo-trading algorithms have access to, but with the added advantage of human sight and human understanding.

Often an unfilled or only partially filled order is because you were too far back in the order book queue. Orders ahead of you were filled, but there were not enough shares for sale to fill every order and trade through your price. The prospect of going home empty-handed is alpha-destroying for algorithmically-driven traders, which makes the queue position critical for high-speed algorithmic traders. A whole set of complex mathematics applies to determining the value of any given position in an order book queue. Level II market data shows multiple bid and ask prices from Nasdaq for any given security so investors can better determine the availability or desire for a security at a certain price. For Nasdaq, bids are functionally equivalent to limit buy orders that other investors have open on the markets. Similarly, asks are functionally equivalent to limit sell orders from other investors.

Charts display the historical price action based on trades executed so that traders can spot price trends and speculate on future direction. Remember that the bids and asks only imply the ‘intent’ of buying and selling, not actual buying or selling. Only when orders are matched, filled and executed does the intent become real. Orders book imply the future direction, but the charts confirm it with actual trade executions. In a nutshell, level 2 should be used in conjunction with Time and Sales and charts for a more complete analysis of price action.
