The information from the TASE orders was used to recreate the dynamics of the limit order book, classifying each incoming order to the bid or ask side, while keeping a record of the previous orders and executing a transaction whenever a match occurred. As a benchmark, we compared the trading output from our simulation to the actual transaction records and verified the two were identical. Next, we proceeded to capture the order book layers’ status after every transaction. Since there were few restrictions on the volume of orders, the volume could change freely between the layers, and indeed, the volume data included a wide variety of different values.

Although the SSM has a distinct structure, its intraday patterns are surprisingly similar to those found in other markets with different structures. We find that liquidity, as commonly measured by width and depth, is relatively low on the SSM. However, liquidity is exceptionally high when measured by immediacy. Limit orders that are priced reasonably, on average, have a short duration before being executed, and have a high probability of subsequent execution.

Niu et al. studied the valuation of vulnerable European options incorporating the reduced-form approach, which models the credit default of the counterparty. Fosset et al. proposed an actionable calibration procedure for general Quadratic Hawkes models of order book events and found that the Zumbach kernel is a power-law of time, as are all other feedback kernels. 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. Dugast studied the same model and proposed a prediction that positive market order imbalance, negative depth, and cancellation imbalances contribute a positive change in price. Following market news, he found that order flows become unbalanced, and market depth is consumed, leading to positive covariance between price variability and order book unbalances. Prior to news arrival, trading occurs because of differences in private valuations, though at prices generally in line with the asset value.

Associated Data

The limit order book of an asset lists the volume of pending buying or selling orders at given prices for the asset under consideration and here we analyse its variance-covariance structure. At a fixed time point, the order book essentially represents a snapshot of the asset’s demand and supply curves above the market equilibrium quantity level. The volume to be potentially bought forms the asset’s demand side, whereas the volume to be potentially sold depicts the asset’s supply side. To be more precise, the order book bid and ask curves represent liquidity supply, thus quantities above the equilibrium volume level, as orders below the equilibrium have been traded at the market. Multivariate techniques are, for example, recently used in financial econometrics of limit order book markets.

The price of the companies indeed reacted positively during this day. For most of the relatively illiquid large-cap stocks, interestingly, the same factor has been identified on both days. Its magnitude changed, as evident from the principal components analysis. A major challenge in measuring the entropy of the order book layers was the fact that each layer of the book is described by side (e.g., bid or ask), volume, and price. Since our data are comprised of discrete and continuous variables (e.g., price and volume, respectively), we split the dataset based on the different values of the discrete random variable and used the conditional entropy to sum the entropies. The trading activity dataset, which was provided directly by TASE, was comprised of one text file for all order submissions and another text file for executed transactions. Table 1 shows several summary statistics for each of the five securities. The information provided here is for general informational purposes only and should not be considered an individualized recommendation or personalized investment advice.

In most practical applications, an order book contains bid and offer for one security, contract or good, with a specialist matching orders for the specific item. The book depth refers simply to the number of price levels available at a particular time in the book. Sometimes the book is represented to a fixed depth, and orders beyond that depth are ignored or rejected, and in other cases the book can contain unlimited levels. Underlying AssetUnderlying assets are the actual financial assets on which the financial derivatives rely. Thus, any change in the value of a derivative reflects the price fluctuation of its underlying asset. Such assets comprise stocks, commodities, market indices, bonds, currencies and interest rates.

How much is 1 lot of shares?

Another important benefit for using the order book is that it shows you the level of liquidity in the market. Ideally, by just looking at the flows of orders in a particular asset, you will be at a good position to understand how liquid or illiquid they are. We can see that the linear effect is not as apparent as the estimations from constituents of S&P 500 by Cont et al. . And the R-squared is relatively much lower compared with stocks in US stock market. Figure 2 presents a scatter plot of against of one stock for every 10 seconds in a whole month.

The most common types of orders are market orders, limit orders, and stop-loss orders.

This type of order guarantees that the order will be executed, but does not guarantee the execution price. A market order generally will execute at or near the current bid or ask price. However, it is important for investors to remember that the last-traded price is not necessarily the price at which a market order will be executed. We had sufficient data to calculate the entropy for the first five layers of the book; e.g., we had five layers of data in every snapshot. However, we realized that particularly in a small stock exchange such as the TASE, we sometimes may not have data for deeper layers, which would make entropy estimation difficult . 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. Each of the stocks had a minimum price increment, or interval, defined by the TASE.
