The concept of the weighted deviation is an extension of the simple linear weighted deviation model. With linear weighting incorporated into every calculation step, the result is an indicator that functions differently than the standard deviation when a linear weighted moving average is operative. Its responsiveness surpasses that of the standard deviation, reinforcing its utility in a variety of scenarios. This deviation indicator can be employed in the same way as any other deviation indicator for nuanced technical analysis. It offers a more refined data interpretation, thereby enhancing the overall efficiency of the trending strategy.

Principal Component Analysis (PCA) is a widely utilized technique across various fields such as image processing, finance, and machine learning. PCA helps in reducing the dimensions of large data sets by transforming a set of variables into a smaller one that still encapsulates the majority of the information from the larger set. This process not only simplifies the data, allowing for easier visualization and analysis, but also enhances the efficiency of machine learning algorithms.

Key steps in the PCA algorithm include standardizing the data, finding the covariance matrix, eigenvectors, eigenvalues, PCA scores, and finally, obtaining the principal components. Standardization is crucial as it normalizes the data, ensuring that each variable contributes equally to the analysis and preventing bias due to varying scales or units.

Understanding PCA and its implementation can significa...

In the rapidly evolving field of algorithmic trading, the integration of machine learning and data mining techniques has become essential for uncovering hidden patterns in financial data. Yun Li, Jennie Si, Guojing Zhou, Shasha Huang, and Songcan Chen have introduced a notable contribution, the "FREL: A Stable Feature Selection Algorithm." This research leverages the algorithm Feature Weighting as Regularized Energy-Based Learning (FREL) to enhance feature selection.

FREL is based on weighted nearest-neighbour classification, refining prediction accuracy by assigning appropriate weights to each feature. This method is differentiated from the standard k-nearest neighbor (k-NN) algorithm by utilizing weights based on the proximity of the data points, typically calculated using metrics such as the Manhattan distance.

The conceptual foundation of FREL lies within energy-based models, wh...

The new Expert Advisor (EA) tool focuses on trading signal efficiency by utilizing specific technical indicators across multiple timeframes. This EA initiates buy orders based on MACD divergence on the 5-minute chart, combined with conditions where the stochastic main line on the 1-hour timeframe surpasses its signal line within the 0-40 range. Additionally, a daily EMAs crossover where the 9-period EMA exceeds the 20-period EMA supports the buy signal, further validated if the 5-minute price bar closes beneath the 9 EMA of the daily chart.

Sell orders are executed under the inverse conditions. The EA's strategy includes precise entry points and exits based either on predefined stops and targets or when the 7-period RSI on any given chart exceeds the 77 mark, indicating an overbought scenario.

Optimized for minimal trading frequency, this EA requires extensive backtesting, ideally ...

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...
