In this paper, we focus on a new generalization of multivariate general compound Hawkes process (MGCHP), which we referred to as the multivariate general compound point process (MGCPP). Namely, we applied a multivariate point process to model the order flow instead of the Hawkes process. Law of...

On 20 April 2020 the West Texas Intermediate (WTI) oil futures price for May delivery turned negative for the first time in history. Other crude prices also posted very low values and their volatility soared, far more than that on stock markets. This article analyses the differences between the...

This paper proposes and tests the private information explanation for the time series of pre-FOMC announcement drift through risk reduction. Using transaction-level data, I document the informed trading is in the same direction of the realized returns in the 24-hour window before FOMC...

This paper examines the finite sample properties of novel theoretical tests that evaluate the presence of: a) Brownian motion, b) jumps; c) finite vs. infinite activity jumps. In allowing for Gaussian, t-distributed, and Gaussian-T mixture noise, our Monte Carlo experiment guides a search for...

This paper examines the price discovery process in a two-tier market, specifically the foreign exchange market. The goal is to identify the sources of private information and to gain insights into the process through which that information influences the market price. Using a transactions...

We propose an actionable calibration procedure for general Quadratic Hawkes models of order book events (market orders, limit orders, cancellations). One of the main features of such models is to encode not only the influence of past events on future events but also, crucially, the influence of...

Market prices are noisy signals of economic fundamentals. In a two-period model, we show that if the central bank uses market prices as guidance for intervention, large strategic investors (who benefit from high prices) may temporarily depress market prices to induce a market-supportive...

Modern Algorithmic Trading ("Algo") allows institutional investors and traders to liquidate or establish big security positions in a fully automated or low-touch manner. Most existing academic or industrial Algos focus on how to "slice" a big parent order into smaller child orders over a given...

Bitcoin is traded on exchanges which use an open limit order book. This paper investigates the microstructure of various bitcoin markets with respect to liquidity and private information processing. The markets are found to be fairly liquid, providing liquidity at a stable rate throughout the 24...

Fragmentation has fostered competition among trading venues. While some platforms rely on a preopening phase leading to an opening call auction, some others start the day without such mechanisms. Using a unique dataset of stocks cross-traded on Euronext (which features a pre-open mechanism) and...
