Summary: Fix the top 5 MT4/MT5 issues in 2026: empty server lists (China), Mac EA loading failures, VPS setup, historical data export, and multiple account management.




Based on 2025-2026 user searches, these are the most frequent MT4/MT5 problems and their verified solutions.

1. MT4/MT5 Server Search Returns Empty (China Users)

Problem: The server list is empty when searching for a broker. New users cannot log in, but existing users often work fine.

Why: The broker server list node is periodically restricted. Existing users have cached server addresses.

Solution:
  • Update MT4 to the latest version (currently build 1470+).

  • Use a stable network during the first connection to cache the server address.

  • Manually enter the broker's server IP if known (File > Login to Trade Account).

    • 2. EA Not Loading on Mac MT4

    Problem: The EA cannot be dragged onto a chart, or shows "invalid EA" or "custom indicator not found."

    Causes: 32/64-bit incompatibility, missing DLL files, or disabled automated trading.

    Solution:
  • Enable Auto-Trading: Tools > Options > Expert Advisors > Check "Allow automated trading."

  • Check File Placement: Place .ex4 files in /MQL4/Experts/ and any .dll files in /MQL4/Libraries/.

  • Verify Compatibility: Some Windows-compiled EAs (especially those calling external DLLs) do not work on Mac.

  • Review Logs: Terminal window > Expert tab for specific error codes.

    • 3. How to Set Up a MetaTrader VPS

    Why: To run EAs 24/7 without keeping your PC on.

    Steps:
  • <strong>Purchase a VPS</strong> from a provider optimized for forex (low latency to your broker).

  • <strong>Connect via RDP:</strong> Use Remote Desktop Connection with the provided IP, username, and password.

  • <strong>Install MT4/MT5</strong> inside the VPS (download the installer from your broker).

  • <strong>Copy Your EA:</strong> Place EA files in the MQL4/Experts folder via the VPS desktop.

  • <strong>Enable Auto-Start:</strong> Place an MT4 shortcut in the Windows Startup folder so trading resumes after automatic VPS reboots.

    • 4. Viewing & Exporting Account History / Equity Curve

    Problem: Users want to analyze past performance and generate an equity curve.

    Solution (MT4):
  • Open the Terminal window (Ctrl+T).

  • Click the <strong>Account History</strong> tab.

  • Right-click > "Save as Detailed Statement" (HTML file includes an equity graph).

  • Right-click > "Save as Report" (for a different format).

  • Reference: IG & Gold2u guides [citation:5][citation:10].


    • Solution (MT5):
  • Go to View > <strong>History Center</strong> (Ctrl+U).

  • Select the symbol and timeframe.

  • Click "Download" from the server.

  • For backtesting: Press Ctrl+R, select your EA, set the date range, and start.

    • 5. Adding Instruments & Managing Multiple Accounts

    On Mobile (Android/iOS):
  • Go to Quotes > Tap + (Android) or use the search bar (iOS) to add new symbols [citation:6].


    • Running Multiple MT4 Accounts on One PC/VPS:
  • Run the installer again and change the installation directory for each instance (e.g., .../MT4-1, .../MT4-2). Create separate shortcuts on the desktop [citation:9].
