The article presents a workflow for using a Latent Gaussian Mixture Model to identify hidden structure in technical-indicator data. It introduces mixture components and latent assignments, then describes fitting the model with expectation-maximization, which…

This article describes an object-oriented MQL5 class for placing a bitmap image behind chart data. Users select an image, a symbol-specific logo, or a solid color mode, and can set image transparency. The proposed folder structure keeps background and logo…

The article explains how to build an in-chart documentation viewer for MQL5 programs using the CCanvas class. Its design organizes material into topic tabs and paragraphs, with inline text styles, warning and tip blocks, embedded images, scrolling, and a…

This article presents an account-history dashboard that plots each closed trade's holding time against its net profit. It recovers opening times by matching deals on position ID, keeps closing and reversal deals, and combines profit, swap, and commission. A…

This article explains how to build a visual dashboard for MetaTrader 5 Expert Advisor optimization. It uses the tester's frame events to transfer each completed optimization pass from an agent to a terminal instance, where the data can be displayed and…

This article describes a tool for generating and evaluating new candlestick patterns from six basic candle shapes, split into bullish and bearish variants except for doji. Patterns contain one to three candles, and repetition can be enabled. Users choose…

The article classifies trading risks into those driven by price behavior and those arising from the trading system or operating environment. It treats prices as non-stationary and broadly random, while identifying trends, consolidations, and responses to…

The article presents a reusable structure for Expert Advisors built around separate buy and sell algorithms, each with its own parameters. Its example detects a change in the direction of a smoothed digital moving filter using three closed bars: a…

The article frames price movement as a mixture of an analyzable component and an unpredictable component. Since exact forecasting is impossible, it proposes estimating statistical properties of average price changes over a fixed interval, potentially using…

The article introduces FinAgent, a proposed market analysis agent that combines text and visual information with historical memory, reflection, and trading tools. Its five-part design covers market analysis, retrieval from memory, short- and long-horizon…

This article turns a prior decision-forest classification experiment into a modular MetaTrader Expert Advisor. The classifier assigns bearish, neutral, or bullish labels from completed-bar features; the author uses “regime” to mean a persistent directional…

The article addresses parameter overfitting by proposing that a trading system be optimized across multiple instruments with one shared parameter set. The rationale is that testing across different price behaviors and repeated patterns may provide a more…

This installment extends a cross-platform MetaTrader library for tracking account events. Its central example is StopLimit activation: because the activation is not recorded in account history as a distinct event, the library detects a change in the type of…

This article shows how to express candlestick patterns as explicit rules in MQL5 and organize those rules into reusable detection functions. It introduces price comparisons for bullish and bearish bars, time-series indexing for accessing recent and…

This tutorial describes a reusable MQL class for HTTP communication through WinInet. It outlines the lifecycle of a network session and connection, sending requests, reading server responses, and closing handles. The examples cover retrieving page contents…

This article extends a multi-symbol trading library so it can keep tick histories current as new quotes arrive. The current symbol can be updated from its tick event handler, while a separate library timer polls other tracked symbols. A configurable…

This article explains how to turn a point cloud and its pairwise distances into a Vietoris–Rips filtration for topological data analysis. Vertices enter at zero, edges enter at their endpoint distance, and triangles enter at the longest of their three edges.…

This article explains how to add spoken alerts to an MQL5 expert advisor by connecting it to a local text-to-speech service. The EA constructs dynamic messages for events such as moving-average crossovers, prices, and trade or risk notifications, then sends…

This article describes an MQL5 expert advisor built around a smart money style order block strategy. It identifies potential zones in consolidation ranges, looks for an impulsive move and a fair value gap, and requires both a break of structure and a…

This beginner guide explains how a custom MQL5 indicator is structured by walking through a simple moving average. It describes the average as the sum of recent closing prices divided by the chosen period, and shows how the period and chart shift are exposed…

This article adapts category theory functors to generate short-term S&P 500 trading signals from linked economic calendar data. It models data points such as retail sales, 10-year auction yields, PMI, and CPI as a graph, then uses neural networks to map…

The article introduces Deep Deterministic Policy Gradient (DDPG) as a reinforcement-learning filter for signals derived from moving-average and stochastic-oscillator patterns. It contrasts DDPG’s continuous-valued action output with discrete buy, sell, or…

The article explains how to build a MetaTrader 5 service that runs without a chart, monitors account history, compiles closed positions from their constituent deals, and produces trading summaries for terminal logs and smartphone push notifications. Its…

The article presents KnitPkg as a way to share MQL4 and MQL5 code across expert advisors, indicators, libraries, and utilities without manually copying folders between projects. A project manifest declares dependencies and build settings; package versions…
