Why this exists

MetaTrader 5 is a Windows GUI application with a closed protocol. Running it as a service normally means a Windows box and a human clicking "Login." This project runs the real MT5 terminal under Wine and exposes its Python API as a REST service, so any language or system can drive an MT5 account programmatically.

The hard part is logging in headless, for any broker. MT5 can't discover a broker by name on a fresh install without its encrypted broker directory (servers.dat), and that file can't be generated. This gateway solves it: it resolves the broker's server name to a connectable address and connects directly, so you supply only the account credentials and the server name — never an IP, a directory file, or a VNC session.
