Markov chains are effective for modeling and forecasting time series data in finance. Their simplicity is a primary advantage, relying on probabilistic models without complex assumptions. They are beneficial for financial data, which often exhibit non-stationary behavior.

There are four main types of Markov chain models: discrete-time, continuous-time, Hidden Markov models, and Switching Markov models. The primary types are discrete-time, modeling a system over discrete steps, and continuous-time, modeling over an interval. Probability estimation, often via expectation maximisation, is key for using these models.

Markov chains predict future states based on current status and transition probabilities, making them suitable for various fields like finance, weather, and biology.

In our latest article, we explore the Conformer method for weather forecasting, adapted for improving trading models using MetaTrader 5. Through timeseries data input, the Encoder model optimizes the Actor's policy. To enhance this process, we introduce Reversible Instance Normalization (RevIN), a simple yet effective normalization technique that addresses distribution shifts by normalizing input sequences and denormalizing output sequences. This technique enhances model accuracy by aligning mean and variance, thus improving timeseries forecasting. We also delve into practical implementation in MQL5, using neural layers for normalization and denormalization, enhancing the robustness and adaptability of trading algorithms.

Forecasting future time series prices is crucial in financial markets. Traditional methods often rely on autocorrelation, yet modern approaches like the Transformer model utilize Self-Attention for dynamic autocorrelation. There's a rising interest in frequency analysis, aiding in overcoming autocorrelation complexities. Despite these advances, many methods using the Direct Forecast (DF) paradigm ignore autocorrelation in predicted values, misaligning assumptions and resulting in suboptimal forecasts.

The FreDF method offers a solution by addressing autocorrelation in frequency domain prediction, enhancing DF while retaining its efficiency. It introduces a frequency-based forecast calibration, tested to outperform contemporary methods. This flexible approach integrates with various models, including MQL5. Implementing FreDF involves transforming...

Developing effective trading strategies relies heavily on accurate future price movement predictions. This precision is achieved using complex deep learning models that leverage inherent periodicity and trends in the data. Currency price movements often tie closely to specific trading sessions. Discretizing time series by these sessions reveals periodic and sequential trends, facilitating data decomposition.

This technique enables the development of lightweight forecasting models like SparseTSF. This model simplifies long-term forecasting to basic trend prediction, minimizes data complexity, and significantly economizes computational resources. SparseTSF represents a major innovation by employing minimal parameters while efficiently capturing the essential periodicity and trends of time series data.

Seasonal decomposition is a powerful MQL5 tool to dissect time series data, revealing trend, seasonality, and residual components. By isolating these elements, traders gain insights into market behavior and remove seasonal noise for clearer trend analysis. Implementing this in MQL5 involves using moving averages for trend extraction and separating seasonal patterns through additive or multiplicative models. This technique is invaluable for identifying recurrent market patterns, applicable in trading strategy development. Practical applications include analyzing stocks like Apple's, unearthing seasonal trends in intraday, monthly, or long-term data. This method enhances algorithmic trading by informing machine learning-based forecasts and strategies.
