HOW TO INSTALL AN EXPERT ADVISOR ON MT4

Complete step-by-step guide to installing Expert Advisors on MetaTrader 4

What You Need

Before you begin, make sure you have:

  • MetaTrader 4 installed on your computer
  • An EA file (.ex4 or .mq4 format)
  • A trading account (demo or live)
  • Step 1: Locate the EA File

    After downloading the Expert Advisor, locate the .ex4 file on your computer. This is the compiled EA file that MetaTrader can run.

    Step 2: Open MetaTrader 4 Data Folder

    1. Launch MetaTrader 4

    2. Click on **File** in the top menu

    3. Select **Open Data Folder**

    4. A Windows Explorer window will open

    Step 3: Navigate to Experts Folder

    Inside the data folder:

    1. Open the **MQL4** folder

    2. Open the **Experts** folder

    3. This is where all EAs are stored

    Step 4: Copy the EA File

    Copy your .ex4 file into the Experts folder.

    Step 5: Restart MetaTrader 4

    Close and reopen MetaTrader 4 to load the new EA.

    Step 6: Enable Automated Trading

    1. Click on **Tools** > **Options**

    2. Go to the **Expert Advisors** tab

    3. Check "Allow automated trading"

    4. Check "Allow DLL imports" (if required by EA)

    5. Click **OK**

    Step 7: Attach EA to Chart

    1. Open the **Navigator** panel (Ctrl+N)

    2. Expand **Expert Advisors**

    3. Find your EA in the list

    4. Drag and drop it onto your chart

    5. Configure settings in the popup window

    6. Click **OK**

    Step 8: Verify EA is Running

    Look for a smiley face icon in the top-right corner of the chart. If you see a frown or no icon, check your AutoTrading button and EA settings.
