Offline Reinforcement Learning (ORL) provides a pathway for training models using pre-collected environmental interaction data, significantly optimizing environmental interaction during training phases. This methodology leverages data from various agents to train models comprehensively. However, ORL uses a static dataset which may not fully represent environmental diversity, potentially leading the model to operate outside of the data distribution without appropriate environmental feedback or adequate evaluations from the Critic.

Addressing this issue, the Supported Policy Optimization (SPOT) method incorporates a Variational AutoEncoder (VAE) to enhance policy regularization. This approach adheres strictly to the data distribution by adjusting policy operations within the distribution constraints established by the training dataset. SPOT has demonstrated superior performance over co...

Continuing the discussion on multi-symbol multi-period indicators, this article focuses on enhancing the multi-indicator class to effectively integrate arrow indicators. Arrow indicators, unlike standard ones, do not consistently provide data across all drawing buffers; they only display data (often as EMPTY_VALUE) where the arrow is visible, and empty otherwise.

This characteristic necessitates a refined approach when integrating these indicators into a higher timeframe chart—to avoid overriding actual data points with empty values from a lower timeframe. For instance, when merging M5 chart indicators onto an M15 chart, it’s crucial to selectively transfer non-empty values, ensuring that previously plotted arrows remain intact and visible.

The article proceeds to discuss the technical adaptations required for multi-indicator classes to handle data gaps inherent in arrow indicators....

Understanding the validity of relationships in machine learning model inputs and the predicted variables is essential in the realm of algorithmic trading. To achieve meaningful predictions, the relationships within the data must be real and not just statistically coincidental. This discussion highlights the importance of employing unit root tests on model residuals to check for spurious regressions - models that falsely indicate meaningful relationships due to coincidental statistical errors rather than genuine interdependencies.

Such models can misleadingly show low error metrics, giving a false sense of accuracy and potentially leading to costly mistakes in trading strategies. The text discusses generating synthetic time series data to illustrate how spurious regressions can occur and provides insights into identifying and mitigating them using statistical tests like the Augmented ...
