How to use this guide
Task-focused MetaTrader 5 references for charts, orders, automation, testing, logs and account history, grounded in official documentation. The guide is written for traders, support teams, administrators and integration testers. The collection explains standard terminal concepts and verification steps. Broker configuration, permissions and available symbols can differ.
Use every answer to resolve one operational question: Which terminal feature or record answers the task, and how can the user verify it against the connected account and server? MetaTrader 5 behavior depends on build, broker settings, account mode, symbol specification and permissions. Official help and local evidence both matter.
The supporting set is MetaTrader 5 Help — Client terminal; MetaTrader 5 Help — Trading operations; MetaTrader 5 Help — Algorithmic trading. These links provide standards, regulator material or official product documentation for the subject; they do not imply endorsement, worldwide applicability or a verified feature in a particular deployment. Check the current source, contract, configuration and qualified local advice before a production, trading or compliance decision.
