Get API Access →Is There an API for Colmex Pro?
Yes. MetaTrader API is an independent REST and WebSocket API that bridges Colmex Pro MT4 and MT5 trading accounts to external applications — it is not operated by Colmex Pro and is not a replacement for the MetaTrader desktop app or an Expert Advisor. You connect each Colmex Pro account once with its login, main (trading) password and server; your code then calls the API with an API key, and MetaTrader API handles the live connection to Colmex Pro’s MT4/MT5 servers on your behalf. Once connected, you can retrieve live balance, equity, and margin data, execute or modify trades, and subscribe to real-time quotes, positions, orders and executed trades over WebSocket — all through standard HTTP and WebSocket calls in any programming language. No Expert Advisor, MQL code, or MetaTrader installation is required at any point, and a newly connected account is usually live within 1–2 minutes.
What You Can Do With the Colmex Pro API
- Retrieve live balance, equity, margin, and full trading history via REST
- Open, modify, and close market or pending orders programmatically
- Subscribe to live quotes, positions with live profit, orders and executed trades via WebSocket
- Manage up to 50 Colmex Pro accounts per customer (more on request) from one API key, addressing each account by its id
