Researchers explored the application of Proximal Policy Optimization (PPO), a reinforcement learning algorithm, in a continuous-time broker-trader game with analytically solvable dynamics. They found that while PPO could approximate the optimal strategy under simple conditions, it struggled with complex scenarios involving stochastic order flow. The study also demonstrated that analytical solutions can serve as valuable benchmarks for diagnosing RL performance and as effective starting points for policy adaptation. AI
