Binary classification models are useful for predicting whether tomorrow's closing price will be higher than today's. Logit and probit regression, common techniques within supervised learning, provide a foundation for this analysis. These models utilize price patterns and standardized price increments as predictors to form a training dataset. The resulting trained classifiers are implemented within trading algorithms like LogitExpert EA.

The process begins with data preparation, where features are defined, standardized, and structured for optimal parameter estimation. Maximum likelihood estimation, often combined with methods like L-BFGS optimization and L2 regularization, helps minimize the loss function, mitigating overfitting risks.

Once parameters and covariance matrices are estimated, prediction occurs, generating buy or sell signals. These signals determine ...

Directional Diffusion Models (DDMs) offer an innovative approach to graph representation learning by addressing the limitations of traditional diffusion models that rely on isotropic noise. DDMs incorporate data-dependent, directional noise, which slows down the signal-to-noise ratio decay, preserving crucial anisotropic structures. This leads to better feature extraction for downstream tasks like graph classification. The technique is particularly promising for financial market analysis, where asymmetric and directional patterns are prevalent. Implementing DDMs involves adding directional noise, using a novel kernel in OpenCL, and integrating it with MQL5 for practical application. The framework enhances MetaTrader 5 by facilitating the analysis of market trends and dependencies effectively.

In delving into advanced machine learning, this article addresses a critical but often overlooked component: irreducible error. Beyond the inherent variability and model bias commonly acknowledged, it introduces a third source of error, obscured by abstraction. By examining models from a geometric perspective, practitioners can better understand the manifold mismatch, where predictions poorly align with target realities in their own domains. This discussion extends into practical trading applications, demonstrating enhanced profitability and reduced risk using an improved feedback controller approach. Both developers and traders can benefit from these insights, offering a more intelligent application of machine learning in trading strategies.

Explore the geometric interpretation of machine learning models and their impact on trading strategies. Unlike traditional methods, which merely map inputs to outputs, these models embed target images onto a space defined by inputs, causing potential misalignment and irreducible errors. This nuance affects prediction accuracy, emphasizing the need for multi-step forecasts over direct comparisons. A practical case shows a 153% increase in profitability by leveraging such predictions. Key techniques include the use of ONNX models for cross-platform deployment and the refinement of strategies through analysis of model predictions, aligning coordinate systems for improved trading outcomes without altering the base model.

Markets often operate in cycles of optimism and pessimism, and traditional mechanical strategies can fall short in volatile conditions. To address this issue, advanced machine learning methods such as Variational Autoencoders (VAEs) are introduced for trading strategies. These models compress noisy data into core features, crucial for discerning valid signals amidst market noise.

A significant advance involves the integration of VAEs with binary event encoding, contrasting previous continuous-value pipelines which diluted key signals. This approach enhances signal clarity, stability, and live performance. The MQL5 Wizard facilitates the assembly of trading strategies by combining custom signal classes with machine learning models. This allows for adaptive strategies that are aligned with market dynamics.

The article delves into the complexities of financial machine learning, highlighting a critical challenge faced by algorithmic trading models: label concurrency. In financial time series, labels that overlap in time create dependencies that contradict the Independent and Identically Distributed (IID) assumption of most ML algorithms. This often leads to overfitted models with poor out-of-sample performance. The solution proposed involves sample weighting based on average uniqueness, quantifying the unique information each data point represents and adjusting weights accordingly. This adjustment aims to rectify model training by prioritizing unique data points. The discussion also introduces three methods to handle non-IID data, focusing on bagging techniques and specific measures to enhance model reliability in trading environments.
