Researchers have developed BRaG, a novel framework for stock trading that utilizes adversarial inverse reinforcement learning to learn from diverse expert strategies. This approach aggregates heterogeneous trading styles using a performance-weighted Wasserstein barycenter to create a stable pseudo-expert representation. BRaG then pretrains a trading policy through adversarial imitation learning, which is subsequently refined with actual market rewards and incorporates control barrier functions to manage risk and enforce drawdown limits. Evaluations across US, UK, Indian, and Taiwanese markets demonstrated that BRaG outperforms traditional trading rules and recent deep reinforcement learning methods while maintaining more stable risk characteristics.
