MT4 shows 'No connection' after entering proxy settings on Windows 10. What do I check first?

Check three things in order: (1) Windows Defender Firewall is not blocking terminal.exe or terminal64.exe on port 1080. (2) Antivirus is not intercepting the SOCKS5 handshake — add MT4 to the exclusion list temporarily to test. (3) The host, port, username, and password are copy-pasted from the portal, not typed manually.

Do MT4 proxy settings apply to chart data as well as order flow?

Yes. When a proxy is configured in MT4, all TCP traffic from the terminal — price feed, order submission, account data — routes through the proxy. There is no selective routing within MT4 itself.

My MT4 proxy settings reset every time Windows restarts. How do I fix this?

Run MT4 as Administrator (right-click shortcut ? Run as administrator, or set it in Compatibility properties). Without elevated permissions, MT4 on Windows 10 sometimes cannot write its configuration file across sessions.

How to configure MT4 on Windows 10

Before you start

You need three things:

MT4 installed and able to reach your broker without the proxy first — confirm a clean baseline connection.
Your TradersProxy credentials from the portal: host, port, username, password.
Five minutes and no active trades open.

Step 1 — Copy your credentials

Log in to the TradersProxy portal. Go to your connection details. Copy the host, port, username, and password for your assigned node. Do not type these — copy-paste. One transposed character breaks the connection.

Step 2 — Open the proxy settings in MT4

Navigate to Tools ? Options ? Server tab ? Enable proxy server ? Proxy— button. The proxy dialog opens. On Windows 10, this dialog may require administrator confirmation before changes are saved — accept the prompt if it appears.

Step 3 — Select SOCKS5 and enter the details

Enable the proxy checkbox or toggle. Select SOCKS5 as the protocol. Paste your host into the server/host field. Enter your port number. Fill in the username and password.

If MT4 shows a separate DNS option — resolve DNS through proxy or similar — enable it. This prevents DNS leaks outside the proxy tunnel.

Note: MT4 also supports HTTP proxy. If SOCKS5 fails to connect, switch to HTTP — both protocols use the same host and port from your portal.

Step 4 — Save and restart MT4

Click OK or Apply to save the settings. Fully quit MT4 — do not just minimise it. On Windows 10, proxy changes do not apply to an existing process. Relaunch the platform.

Step 5 — Confirm the connection

Look for MT4's connection indicator after relaunch. A successful proxy connection looks identical to a direct connection — green status bars, server connection confirmed, data flowing. If the indicator stays red or the platform throws a connection error, see the gotchas section below.

Known gotchas on Windows 10

These are the issues traders hit most often when setting up MT4 on Windows 10. Check these before contacting support.

Windows Defender Firewall may block port 1080 on first connection. Go to Control Panel ? Windows Defender Firewall ? Allow an app ? add terminal64.exe (or terminal.exe on 32-bit builds).

MT4 must be run as Administrator on Windows 10 for proxy settings to persist across reboots. Right-click the shortcut ? Properties ? Compatibility ? Run this program as an administrator.

Some antivirus products (Bitdefender, Avast) intercept SOCKS5 traffic and break the handshake. Add MT4's executable to the antivirus exclusion list before testing.

The proxy dialog in MT4 only accepts IPv4 hostnames or IP addresses. If the portal provides a hostname, ensure DNS resolves it before testing.

General rule for Windows 10: run MT4 as the same user account that configured the proxy. Settings saved under an administrator account may not carry over to a standard user session.

Why the proxy settings matter

Most traders use the network path of infrastructure. The platform (MT4) is the tool — free, from the broker. The idea — signals, analysis, a method — is your trading idea. The connection path is the network path every order packet travels from your machine to the broker's matching engine.

The connection path is the one nobody names. Nobody charges for it. So it defaults to whatever your ISP gives you — shared bandwidth, peering decisions made for Netflix, routing paths designed for web browsing.

The proxy settings in MT4 let you replace that default path. TradersProxy puts a clean network relay — purpose-built for trading traffic — between your platform and your broker. Split TCP buffers separate interactive order flow from bulk chart data. The per-connection congestion algorithm adapts to your path conditions in real time.

Four fields in MT4 is how you access that layer. That's the whole setup.
