Towards Multi-Agent Reinforcement Learning driven Over-The-Counter Market Simulations

Nelson Vadori, Leo Ardon, Sumitra Ganesh +7

We study a game between liquidity provider and liquidity taker agents interacting in an over-the-counter market, for which the typical example is foreign exchange. We show how a su…
