In this talk, I present a unified approach that addresses both problems simultaneously in three steps.\r\n\r\nWe introduce a macroscopic market making model \u00e0 la Avellaneda-Stoikov, using continuous processes for orders instead of discrete point processes. Since the impact of a single market maker on price is typically negligible, we then develop the corresponding game formulation. Finally, we can connect traders with market makers.\r\n \r\nSubsequently, we present our mathematical contributions. The goal is to derive the global well\u2011posedness of the optimal control\/Nash equilibrium. The discussion addresses topics in game theory, non\u2011smooth analysis, FBSDEs, and Riccati equations.\r\n\r\nReferences:\r\nIvan Guo, Shijia Jin, and Kihun Nam, Macroscopic Market Making.
