LLM-Based Hierarchical RL for Pair Trading

other · 2026-05-06

A new arXiv preprint (2605.01954) introduces Moira, a language-driven hierarchical reinforcement learning framework for pair trading. The approach uses large language models (LLMs) to parameterize both high-level and low-level policies, optimized through prompt updates. It addresses credit assignment in hierarchical decision-making by leveraging trajectory- and episode-level textual feedback.
