I did not know that MT4 uses FIX!

But I can't speak for Rust or Go. If there isn't one already, there really should be...

Not the MT4 client but the backend seems to use fix according to: https://blackbullmarkets.com/en/platforms/fix-api-trading/

"...MetaTrader 4 (MT4) is the FIX application that BlackBull Markets uses."
