API for 4 Square SY — REST & WebSocket for MT4 & MT5

Operating as 4 Square SY Limited

Connect 4 Square SY MT4 and 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 4 Square SY?

Yes. MetaTrader API is an independent REST and WebSocket API that bridges 4 Square SY MT4 and MT5 trading accounts to external applications — it is not operated by 4 Square SY and is not a replacement for the MetaTrader desktop app or an Expert Advisor. You connect each 4 Square SY 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 4 Square SY’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 4 Square SY 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
