LOB modeling using Hawkes processes with a state-dependent factor

  title={LOB modeling using Hawkes processes with a state-dependent factor},
  author={Emmanouil Sfendourakis and I. Toke},
A point process model for order flows in limit order books is proposed, in which the conditional intensity is the product of a Hawkes component and a state-dependent factor. In the LOB context, state observations may include the observed imbalance or the observed spread. Full technical details for the computationally-efficient estimation of such a process are provided, using either direct likelihood maximization or EM-type estimation. Applications include models for bid and ask market orders… Expand

Analyzing order flows in limit order books with ratios of Cox-type intensities
We introduce a Cox-type model for relative intensities of order flows in a limit order book. The model assumes that all intensities share a common baseline intensity, which may for example representExpand
Hawkes Processes in Finance
In this paper we propose an overview of the recent academic literature devoted to the applications of Hawkes processes in finance. Hawkes processes constitute a particular class of multivariate pointExpand
State-dependent Hawkes processes and their application to limit order book modelling
This work establishes the existence and uniqueness of state-dependent Hawkes processes, and develops maximum likelihood estimation methodology for parametric specifications of the process, and finds that excitation effects in the order flow are strongly state- dependent. Expand
High-dimensional Hawkes processes for limit order books: modelling, empirical analysis and numerical calibration
High-dimensional Hawkes processes with exponential kernels are used to describe limit order books in order-driven financial markets. The dependencies between orders of various types are carefullyExpand
Critical reflexivity in financial markets: a Hawkes process analysis
We model the arrival of mid-price changes in the E-mini S&P futures contract as a self-exciting Hawkes process. Using several estimation methods, we find that the Hawkes kernel is power-law with aExpand
A Stochastic Model for Order Book Dynamics
A continuous-time stochastic model that can effectively capture the short-term dynamics of a limit order book and evaluate the performance of a simple trading strategy based on the results is proposed. Expand
Modelling intensities of order flows in a limit order book
We propose a parametric model for the simulation of limit order books. We assume that limit orders, market orders and cancellations are submitted according to point processes with state-dependentExpand
Queue-reactive Hawkes models for the order flow
This work introduces two variants of multivariate Hawkes models with an explicit dependency on various queue sizes aimed at modeling the stochastic time evolution of a limit order book and provides an explicit way to calibrate this model either with a Maximum-Likelihood method or with a Least-Square approach.

Trade arrival dynamics and quote imbalance in a limit order book
We examine the dynamics of the bid and ask queues of a limit order book and their relationship with the intensity of trade arrivals. In particular, we study the probability of price movements andExpand
Robust identification of controlled Hawkes processes.
This work proposes an alternative approach based on an expectation-maximization algorithm, which instrumentalizes the internal branching structure of the process, thus improving convergence behavior and provides a tight lower bound for maximum-likelihood estimates. Expand
