Trading algorithms with learning in latent alpha models

no code implementations12 Jun 2018 Philippe Casgrain, Sebastian Jaimungal

Under fairly general assumptions, we demonstrate how the trader can learn the posterior distribution over the latent states, and explicitly solve the latent optimal trading problem.
