Download MT4 and connect the account
Open the official Exness destination, find Platforms > MetaTrader 4 and choose the version for your device. In your Personal Area, create or select an MT4 account and note its assigned server and numeric login.
On desktop, use File > Login to Trade Account and enter the trading details. On mobile, add an existing account and select the matching server. Use the demo server for a demo account. Personal Area email/password and MT5 credentials do not replace these fields.

Desktop, phone or browser?
| Version | Useful for | Important limit |
|---|---|---|
| Desktop | Charts, MQL4 EAs and custom indicators | Local automation needs the terminal running |
| Mobile | Monitoring and manual order controls | Does not run desktop EAs |
| MetaTrader WebTerminal | Browser access without installation | No desktop EA or trailing-stop engine |
A first order exercise before live use
Choose a demo symbol, open its specification and read the minimum volume and price precision. Enter a small practice volume, add a stop and target, then read the accepted order. Modify one level, close the position and find the record in account history.
If you plan in HKD but practise on a USD account, label the budget in USD or use an explicit conversion assumption. A Hong Kong device clock also does not establish the server’s session time.
When the connection or EA does not work
Invalid Account usually calls for a credential/platform comparison, while No Connection calls for a server or network investigation. Rescan servers from the connection indicator and keep the precise error for support.
For an EA, use the MT4 version of the code, enable its required trading permission and review the Experts and Journal records. Do not enable unrelated external permissions to solve a login failure. Exness warns that aggressive request settings can disable an EA.
CFD trading risk
Leveraged CFDs can cause substantial losses, including the money in your trading account. Margin is not a loss limit, and a stop-loss does not guarantee its execution price.
