How to Install Expert Advisor (EA) in MetaTrader 4 and 5
Expert Advisors (EAs) are automated trading programs that run on MetaTrader 4 (MT4) or MetaTrader 5 (MT5). They help traders execute trades automatically based on pre-defined strategies. If you’re new to algorithmic trading, this guide will teach you exactly how to install an Expert Advisor step by step.
🔹 Step 1: Download or Create Your EA File
The first step is to have your Expert Advisor file ready. EA files usually come in two formats:

You can download free or paid EAs from trusted sources or code your own using the MetaEditor tool inside MetaTrader.
🔹 Step 2: Open the MetaTrader Platform
Launch your MT4 or MT5 platform. Ensure that it is connected to your broker account and running properly. Now you’re ready to add the EA to the platform.
🔹 Step 3: Locate the “Experts” Folder
Click on File → Open Data Folder. A new window will open showing the MetaTrader directory. From here:
- Open the MQL4 or MQL5 folder.
- Then open the Experts folder inside it.
- Copy your EA file (.ex4 or .ex5) into this Experts folder.
🔹 Step 4: Restart MetaTrader
Close and reopen your MetaTrader platform. This refreshes the system and makes your EA appear in the Navigator panel under “Expert Advisors.”
🔹 Step 5: Attach the EA to a Chart
Go to the Navigator panel on the left side. Under “Expert Advisors,” find your EA name. Drag and drop it onto the chart of the currency pair you want to trade.
A settings window will appear. Check the boxes for “Allow live trading” and “Allow DLL imports” if required.
🔹 Step 6: Enable AutoTrading
At the top of your MetaTrader window, click the “AutoTrading” button (MT4) or “Algo Trading” button (MT5). When it turns green, your EA is active and ready to trade automatically.
✅ Final Tips for Using EAs
- Always test your EA in a demo account before going live.
- Use a VPS for 24/7 EA operation without interruptions.
- Monitor performance regularly to adjust strategy or risk settings.
