В статье рассматриваются параметры второго этапа конвейера автоматической оптимизации мультивалютного советника. Мы анализируем критерии фильтрации проходов первого этапа и правила формирования групп торговых стратегий. Демонстрируется влияние настроек на результаты оптимизации, обсуждаются аспекты надёжности процесса и баланс между строгостью отбора и достаточностью кандидатов для алгоритма.

The article examines two practical aspects of the Adwizard-based optimization pipeline: diagnostics and recovery after failures when generating the final Expert Advisor database, as well as preliminary selection of strategy parameter ranges before project creation. It is shown how analyzing the stages/jobs/tasks tables in SQLite and restarting stages based on their statuses help restore the process, while trial optimization narrows the search space, eliminates redundant parameters, and reduces the risk of getting stuck at local maxima.

The article outlines the complete process of creating a multi-currency Expert Advisor using the Adwizard library for MetaTrader 5: from setting up the environment for creating optimization projects to obtaining the final multi-currency Expert Advisors, which combine multiple instances of a simple trading strategy. We will walk through setting up the necessary input parameters, conventions for convenient file names, and launching three instances of the final Expert Advisors on different trading accounts with different parameters.

We are adding to our web application the ability to retrieve and display information about the terminal instances’ trading accounts, including balance, profit, connection status, and other important details. We will also implement a flexible configuration system that lets you manage application settings via an external JSON file, and improve the user interface of the main page.
