History of MQL5.community development

A market-neutral trading strategy based on the empirical return distribution offers an alternative to traditional technical analysis methods, replacing price direction forecasting with the statistical placement of orders at levels the price is likely to reach. This article provides a detailed analysis of the mathematical framework for calculating percentiles, algorithms for weighting position sizes based on the probability of an order being triggered, and mechanisms for adapting to changing market conditions through grid expiration. A complete implementation in MQL5 is provided.

The Crow Search Algorithm (CSA) is an elegant metaheuristic inspired by crows’ ability to hide food and find other crows' caches, solving optimization problems by balancing following successful solutions with random exploration of the search space. Let's find out how well the algorithm performs.

The article discusses flat (non-directional) and trend-following (directional) option strategies and their implementation in MQL5. The EA described in the previous article is updated. The display of option levels has been added. Now it is time to examine the strategies used by options traders in practice and put them into action.

The EA learns each symbol's volatility profile before trading by processing 1000 bars and summarizing candle ranges, bodies and wicks, noise ratio, trend runs, pullback size, and true‑range dispersion. A classifier assigns regime and structure labels per pair. The stop‑loss optimizer maps those labels to a symbol‑specific ATR multiplier, and the risk module sizes lots to maintain constant percentage risk.

Learn to assemble an MT5 Expert Advisor that hosts a chart management dashboard written in MQL5. The guide walks through shared definitions, symbol acquisition and filtering, chart lifecycle functions, and a UI panel with search, scrolling, and state indicators, all driven by events and a timer. The result is a reproducible tool that reduces clicks and accelerates multi-symbol analysis.

This article builds a complete MQL5 Expert Advisor that implements the original Turtle Trading rules from Curtis Faith. It covers both systems: 20/55-day breakouts, the System 1 skip rule, N (Wilder ATR) for volatility-adjusted sizing, a four‑unit pyramid with N/2 adds, a unified 2N stop, and 10/20-day exits. You will get compilable code, implementation details, and a backtesting procedure on EURUSD.

This article presents TrendTemplateEA, an Expert Advisor implementing Mark Minervini's eight-condition trend template for daily forex charts. It evaluates all conditions on every bar and enters only when they are simultaneously satisfied, using RSI above 50 in place of the stock market RS rating. The entry trigger is a 20-bar high breakout on expanding volume, with all rules coded and testable in MQL5.

We are going to improve the usability of the automated optimization conveyor: we will explore the process from creating an optimization project to testing the final EA. For clarity, let us walk through the entire process step by step creating the final EA, while stopping to make any desired corrections.

This article demonstrates a practical approach to researching trading ideas using a range breakout strategy as an example. We will go through the entire process, from formalizing trading rules and building a baseline model to parameter optimization, forward testing, and evaluating the robustness of the results. The main goal of the article is to develop an understanding of how statistics and testing can be used to identify, validate, and evaluate trading hypotheses.

The article builds an MQL5 Expert Advisor that writes a self-refreshing HTML positions dashboard to MQL5/Files on every tick, so you can monitor open trades in any browser. It covers reading live position data, generating a complete page with inline CSS and a JavaScript reload timer, and writing the file atomically. The design escapes HTML in comments, shows an explicit empty state, and writes a clear offline page on EA shutdown.

Stop-loss and take-profit placement is usually the least-measured decision in a trading system. This Expert Advisor reads your closed history, replays M1 price between each entry and exit to measure Maximum Adverse and Favorable Excursion per trade, and splits winners from losers. From the distributions and trade efficiency it derives data-driven stop and target levels - measured from your own account, not a rule of thumb. Analysis only; it does not trade.
