This article describes combining copula families to represent dependence patterns that a single family may miss. It outlines mixtures of Clayton, Frank, Gumbel, and Student-t copulas, whose differing tail behavior can capture joint extremes as well as…

The article explains Eagle Strategy, a population-based optimization method that alternates broad search with focused refinement. In its global phase, agents take Lévy-distributed steps, generated with the Mantegna method, to explore distant parts of the…

This article presents a program structure for tracking many open and pending orders in an MQL4 expert. A dedicated routine runs on each tick before strategy logic, collects order attributes into globally available arrays, and supports comparisons between…

The document develops rule based signal patterns for a wizard assembled MQL5 Expert Advisor, focusing on late Bollinger Band patterns and RSI. One pattern treats expanding bands after a prior trend as a possible contrarian reversal: widening after a rise…

This article describes adding currency, importance, and time filters to an MQL5 economic calendar dashboard. Boolean settings enable or disable each filter; arrays define accepted currencies and event importance levels, while a time window selects events…

The article describes refinements to a market replay and simulation service. It restricts backward movement after replay has advanced, using visual states for the slider's left and right fine-tuning controls to show when movement is unavailable. The…

This installment describes preparing a multi-currency expert advisor for real use by extracting selected strategy-group initialization data from a large optimization database and packaging it with the EA. The workflow has three stages: select groups and save…

The article explains a forex zone recovery approach and walks through building an MQL5 expert advisor to illustrate it. A first position is opened from an RSI signal; if price moves against it to a preset level, the system opens a larger opposing position.…

The article develops a pipeline for identifying market regimes from lagged moving-average features and applying the results in an MQL5 trading system. It uses independent component analysis (ICA) to reduce feature noise, time-series cross-validation to…

This guide demonstrates how to inspect, test, and modify MetaTrader 5’s BullishBearish MeetingLines Stoch Expert Advisor. The default program looks for Three Black Crows and Three White Soldiers patterns, then confirms them with Stochastic readings. The…

The article explains how to build a custom MQL5 Wizard signal using regression analysis rather than relying only on built-in indicator signals. It describes solving for regression coefficients with matrix LU decomposition, then estimating forecast error and…

The article presents the Eco-inspired Evolutionary Algorithm (ECO), a population-based metaheuristic that searches with multiple evolving subpopulations. It periodically groups populations into habitats according to the distance between their centroids.…

The article explains two ways to use clustering results in a trading model. As a standalone method, a trained clustering model assigns historical market states to clusters, and labeled examples are used to estimate the frequency of buy, sell, or neutral…

The article describes preprocessing components for Mamba4Cast, a state-space time-series forecasting framework. It explains how an embedding module combines convolutional projection, normalization, and temporal encoding, and how its initialization allocates…

This article describes adding a Donchian Channel breakout strategy to a candlestick trend-constraint Expert Advisor. The channel’s upper and lower bands represent the highest high and lowest low over a specified lookback, with a middle line at their average.…
