API for Arbitrage Prime — REST & WebSocket for MT5

Operating as Arbitrage Prime Limited

Connect Arbitrage Prime MT5 accounts to a professional REST & WebSocket API. Retrieve live balances, execute trades, and stream real-time market data programmatically — no MetaTrader installation, no Expert Advisor, no MQL required.

Is There an API for Arbitrage Prime?

Yes. MetaTrader API is an independent REST and WebSocket API that bridges Arbitrage Prime MT5 trading accounts to external applications — it is not operated by Arbitrage Prime and is not a replacement for the MetaTrader desktop app or an Expert Advisor. You connect each Arbitrage Prime 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 Arbitrage Prime’s 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 Arbitrage Prime 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 Arbitrage Prime accounts per customer (more on request) from one API key, addressing each account by its id
