Add and use an Expert Advisor (EA) with MT4
You can either create an EA from scratch, or import one someone else has made. While they’re called ‘expert’, it is always worth researching EAs thoroughly and testing them on a demo account before using them for live trading.
When you’re ready to try an EA, here’s how to:
1. Add an EA to a market
The EAs currently installed on your system are listed in the ‘Navigator’ panel. Simply drag and drop your chosen EA on top of the price chart of the market you would like it to trade or monitor. This will bring up a settings window, where you can customise how you want the EA to run.
2. Remove or edit an EA
To remove an EA, simply right click on the price chart of the market it is running on, hover over ‘Expert Advisors’ and select ‘remove’ from the drop-down menu. To edit the EA instead, select ‘properties’ from this drop-down menu to open the settings window.
3. Buy or rent a new EA
There are thousands of EAs available to buy through MT4’s market. Open the ‘terminal’ window (Ctrl + T) and navigate to the ‘market’ tab. Click the ‘experts’ tab at the top of the ‘terminal’ window to see a list of available EAs. Once purchased or rented, the EA will appear in the list in your ‘navigator’ window.
