FXCopyNex exposes a REST and WebSocket API for account discovery, positions, order history and order control. Use the manager API credentials issued by your broker platform, or connect through the hosted bridge.
MT4 and MT5 accounts can follow each other. Symbol suffixes, contract sizes and account modes (netting or hedging) are mapped automatically.
For private deployments, the engine runs on your own PC or VPS. Signal sources and credentials stay under your control.
