Continuing the examination of MQL5 wizard capabilities, Bayesian inference emerges as a significant statistical tool for updating probabilities with new data. This method remains particularly useful in forecasting time series, critical in financial markets where traders primarily analyze security prices and trade histories. The premise of Bayesian inference is to increase the adaptability of trading systems by continuously updating hypotheses, which potentially reduces curve-fitting errors during historical data tests and future applications.

Bayesian Inference operates on the formula P(H|E) = [P(E|H) * P(H)] / P(E), where H symbolizes the hypothesis and E stands for evidence. This formula facilitates recalibrations based on new data, though challenges remain in determining P(E|H) effectively.

Practical applications in trading using Bayesian inference can be typified through signal,...

Quantile Regression and Its Implementation in MQL5 for Enhanced Reward Prediction in Distributed Q-learning

Quantile regression significantly advances distributed Q-learning by modeling the probabilistic distributions of expected rewards which, unlike traditional methods, does not break the range of reward values into discrete sections, but rather divides the set of received rewards into several equally likely quantiles. This approach eliminates zero-probability rewards typically seen in sparse reward distributions and provides a more accurate depiction of possible outcomes at different quantile levels.

This article introduces the implementation of the quantile regression algorithm through MQL5, aiming to optimize expert advisors by integrating a robust framework for predicting median rewards values across various action outcomes. The unique method divides a dataset into equal proba...

Triangular arbitrage in Forex and cryptocurrencies is a strategy that exploits discrepancies between three currencies to make a risk-free profit. The technique operates on the principle that the product of three exchange rates should logically equal one, but due to market inefficiencies, this isn't always true, creating opportunities for arbitrage.

The recent integration of deep learning models into triangular arbitrage strategies enhances the ability to predict and capitalize on these market inefficiencies more effectively. For instance, using ONNX models with Python allows traders to implement these strategies on platforms like MT5. This method requires an initial setup including the installation of Python and Visual Studio Code, followed by specific libraries essential for running the predictive models.

The application, detailed through a provided expert advisor (EA), demonstrate...

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...
