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. 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. 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.

The full mutual information results are shown in Appendix A, Table A2, and the statistical analysis can be seen in Table 4. The results show that the phenomena observed with the initial smaller set is also significant across all of the TA-35 stocks. The p-value of each MI calculation was estimated by shuffling the value of layer j 1000 times and counting the number of times that the MI calculation was higher than the one calculated with actual data. The first took a snapshot after every transaction, the second took a snapshot after every two transactions, and the third took a snapshot after every three transactions. We took this as evidence against the hypothesis that sampling the snapshots after each transaction affected the results. The constraint on makes the solutions nonlinear in the and there is no closed form expression as in ridge regression. Because of the nature of constraint, making sufficiently large will cause some of the coefficients to be exactly zero. Gives the uniform consistency and a functional central limit theorem for the LASSO regularization path for the general linear model. Since the number of explanatory variables p being quite large, it is of interest to perform a variable selection procedure to select the most important variables.

For comparison, we select data of two months, respectively; one is the month with normal trading volume, and the other is the month with highest trading volume and booming liquid in recent years.

The study of high-frequency quote data indicates that this is an empirically relevant case for many liquid stocks. For the buy side, they find that the imbalance between arriving intensity of limit orders and intensities of market orders + cancelations is around 5% or less for these stocks.

Factors to consider include, for example, the number of competitors in the sector, if there is a surplus then new companies may find it difficult to enter the market and remain in business. The method is the generalisation of a linear regression model when dependent variable is discrete.
Generally, the limit order book in small exchanges repopulates slowly (e.g., the order book has low resilience), which underscores the importance of studying the layer depth. This order results in 5 shares being exchanged at price 1.3, 20 shares exchanged at price 1.4, and the remaining 25 shares in the order are now waiting in the order book at price 1.4 on the bid side. Figures 7 and 8 show how many times a variable is selected as the first selected variable by LASSO. We denote the i events lagged log volume on the bid limit price by . Similarly, i events lagged log market order volume is denoted by and i events lagged binary variables are denoted by, , , etc. For the sake of simplicity, for each selection order, we show the frequency distribution of the five most frequently selected variables among 746 backtests in each figure.
