The platform you can use depends on your demo account type. 

• MT4 or MT5 demo account: Trade using the MT4/MT5 desktop application, MT4/MT5 mobile, or MT4/MT5 WebTrader (browser-based). 

• Axi demo account: Trade using the Axi mobile app or the web platform via the Client Portal. 

Important: 

Make sure you use the platform that matches your account type. MT4/MT5 demo accounts only work with MT4 or MT5 platforms, and Axi demo accounts can only be used on the Axi Trading Platform.
