Outlier-robust Kalman Filtering through Generalised Bayes

1 code implementation9 May 2024 Gerardo Duran-Martin, Matias Altamirano, Alexander Y. Shestopaloff, Leandro Sánchez-Betancourt, Jeremias Knoblauch, Matt Jones, François-Xavier Briol, Kevin Murphy

We derive a novel, provably robust, and closed-form Bayesian update rule for online filtering in state-space models in the presence of outliers and misspecified measurement models.

A Mean Field Game between Informed Traders and a Broker

no code implementations10 Jan 2024 Philippe Bergault, Leandro Sánchez-Betancourt

In the finite player game, the informed traders observe a common signal and a private signal.

Detecting Toxic Flow

no code implementations10 Dec 2023 Álvaro Cartea, Gerardo Duran-Martin, Leandro Sánchez-Betancourt

This paper develops a framework to predict toxic trades that a broker receives from her clients.

Information-Based Trading

no code implementations21 Jan 2022 George Bouzianis, Lane P. Hughston, Leandro Sánchez-Betancourt

We consider a pair of traders in a market where the information available to the second trader is a strict subset of the information available to the first trader.

Pricing with Variance Gamma Information

no code implementations17 Mar 2020 Lane P. Hughston, Leandro Sánchez-Betancourt

A cash flow $H_T$ is taken to depend on the market factor $X_T$, and one considers the valuation of a financial asset that delivers $H_T$ at $T$.

Latency and Liquidity Risk

no code implementations8 Aug 2019 Álvaro Cartea, Sebastian Jaimungal, Leandro Sánchez-Betancourt

The interaction between the LOB and MLOs is modelled as a marked point process.

Lévy-Ito Models in Finance

no code implementations19 Jul 2019 George Bouzianis, Lane P. Hughston, Sebastian Jaimungal, Leandro Sánchez-Betancourt

We present an overview of the broad class of financial models in which the prices of assets are L\'evy-Ito processes driven by an $n$-dimensional Brownian motion and an independent Poisson random measure.
