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:
    1. Purchase a VPS from a provider optimized for forex (low latency to your broker).
    2. Connect via RDP: Use Remote Desktop Connection with the provided IP, username, and password.
    3. Install MT4/MT5 inside the VPS (download the installer from your broker).
    4. Copy Your EA: Place EA files in the `MQL4/Experts` folder via the VPS desktop.
    5. Enable Auto-Start: Place an MT4 shortcut in the Windows Startup folder so trading resumes after automatic VPS reboots.

    • 4. Viewing & Exporting Account History / Equity Curve

    2. Click the Account History tab.
    3. Right-click > "Save as Detailed Statement" (HTML file includes an equity graph).

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


    • Solution (MT5):

    2. Select the symbol and timeframe.

    • 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].
