Check out the new article: How to Create and Adapt an RL Agent with an LLM and Quantum Encoding for Algorithmic Trading in MQL5.

The article proposes a hybrid approach to algorithmic trading based on quantum encoding of market states, Double DQN with a prioritized experience replay buffer, and an LLM acting as a contextual EA. The SEAL methodology enables asynchronous continued training of the agent without halting trading. A lightweight Q-learning filter (USE/SKIP/REDUCE) controls signal execution at the meta-level. Practical details are provided on integrating the system with the MetaTrader 5 trading platform, along with a scheme for adapting it to market regime shifts.

A paradoxical situation has emerged in modern algorithmic trading: despite the impressive achievements of machine learning in other fields, the application of reinforcement learning to trading in financial markets remains a challenge with extremely inconsistent results.

This work presents a hybrid approach that combines the advantages of quantum encoding of states, deep Q-learning, and language models with the SEAL (Self-Evolving Adaptive Learning) self-adaptation mechanism. The system's practical implementation demonstrates its ability to automatically filter out ineffective trading signals and dynamically adapt to market regime shifts without the need to completely retrain the model. The architecture is based on the principle of minimal invasiveness: the RL agent integrates into existing trading systems, enhancing their decision-making capabilities without replacing the underlying logic.
