Abstract: While Large Language Model (LLM) agents show promise in automated trading,
they still face critical limitations. Prominent multi-agent frameworks often
suffer from inefficiency, produce inconsistent signals, and lack the end-to-end
optimization required to learn a coherent strategy from market feedback. To
address this, we introduce AlphaQuanter, a single-agent framework that uses
reinforcement learning (RL) to learn a dynamic policy over a transparent,
tool-augmented decision workflow, which empowers a single agent to autonomously
orchestrate tools and proactively acquire information on demand, establishing a
transparent and auditable reasoning process. Extensive experiments demonstrate
that AlphaQuanter achieves state-of-the-art performance on key financial
metrics. Moreover, its interpretable reasoning reveals sophisticated
strategies, offering novel and valuable insights for human traders. Our code
for data acquisition and agent training is publicly available at:
