The MetaTrader platform can run on the Microsoft Windows 2008/7/8/10 operating systems. The platform also requires a processor with SSE2 support (Pentium 4/Athlon 64 or higher). The rest of the hardware requirements depend on the specific features and scenarios used on the platform, such as loads from running MQL5 programs, the number of active instruments, charts, etc.
