Trading in CEXs and DEXs with Priority Fees and Stochastic Delays
Philippe Bergault, Yadh Hafsi, Leandro Sánchez-Betancourt
We develop a mixed control framework that combines absolutely continuous controls with impulse interventions subject to stochastic execution delays. The model extends current impul…
Reinforcement Learning in Queue-Reactive Models: Application to Optimal Execution
Tomas Espana, Yadh Hafsi, Fabrizio Lillo +1
We investigate the use of Reinforcement Learning for the optimal execution of meta-orders, where the objective is to execute incrementally large orders while minimizing implementat…
Optimal Execution under Liquidity Uncertainty
Etienne Chevalier, Yadh Hafsi, Vathana Ly Vath +1
We study an optimal execution strategy for purchasing a large block of shares over a fixed time horizon. The execution problem is subject to a general price impact that gradually d…
Optimal Execution with Reinforcement Learning
Yadh Hafsi, Edoardo Vittori
This study investigates the development of an optimal execution strategy through reinforcement learning, aiming to determine the most effective approach for traders to buy and sell…
