Check out the new article: Working with ONNX Models in MQL5 (Part 2): Drawing the Model Graph on an Interactive Chart Panel . We turn the ONNX reader into an interactive graph viewer on a MetaTrader 5 chart. The parser is extended to carry tensor shapes and node attributes, and a canvas with

Check out the new article: Price Action Analysis Toolkit Development (Part 78): Extending the Indicator Search Panel with Symbol Selection in MQL5 . We continue enhancing our modular indicator search panel by adding symbol selection capabilities. The implementation allows users to search for

Check out the new article: Wasserstein Distance for Live Feature-Drift Detection in MQL5: Monitoring ONNX Model Inputs with Optimal Transport . This article implements a lightweight feature-space drift guard in MQL5 using 1D Wasserstein‑1: sort-and-pair scoring on equal windows, IQR normalization

Check out the new article: Position Management: Deriving a Self-Calibrating Exit Ladder From Historical MFE in MQL5 . We implement three MQL5 classes that replace fixed 1R/2R/3R targets with data-driven scale-out levels. CExcursionTracker records each closed trade's maximum favorable excursion in R

Sensible Guide Confluence : H1 indicator that combines support/resistance confluence from H4, D1 and W1 with EMA trend alignment and candlestick confirmation. Shows non-repainting BUY/SELL arrows with ATR-based stop and reward/risk filtering. Author: Marian Beceanu

New article MetaTrader 5 on Linux is published: In this article, we demonstrate an easy way to install MetaTrader 5 on popular Linux versions — Ubuntu and Debian. These systems are widely used on server hardware as well as on traders’ personal computers. Author: MetaQuotes

Check out the new article: Automating Trading Strategies in MQL5 (Part 13): Building a Head and Shoulders Trading Algorithm . In this article, we automate the Head and Shoulders pattern in MQL5. We analyze its architecture, implement an EA to detect and trade it, and backtest the results. The

Neural Loss-Pattern Auditor : Neural Loss-Pattern Auditor trains a small feed-forward neural network, written from scratch in native MQL5, on closed-deal history to test whether behavioral and market-context features predict which trades are more likely to lose. It reports an accuracy uplift over a
