MetaTrader Build – This specifically refers to the build number of the MetaTrader platform (MT4/MT5). Each MetaTrader release has a unique build ID. Developers can obtain the terminal’s build number in MQL code (e.g. if(TerminalInfoInteger(TERMINAL_BUILD) >= 3500) { ... }
). The build number is often used for conditional code: for instance, enabling new features only on recent builds. It is also useful for bug reporting, as problems may be specific to certain builds. Broker support and forums frequently refer to the build number when diagnosing issues.
