Is There an API for Castle Market?

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