Hello Trader/MQL4,

                           I have purchased an EA in .ex4 file and wanted to know how to download/upload it onto my MT4 Trading Platform. Any advise or instructions are greatly appreciated. Thank you in advance.

1. Open your MT4 platform.

2. Open the chart of the instrument that you want to trade with (currency, stock, commodity or index).

3. Copy the .ex4 file of your expert advisor (I believe this is what you call automated trading robot) and paste it in the: File >> Open Data Folder >> MQL4 >> Experts folder of your MT4 platform.

4. Right click on the Refresh option of your Experts Advisors folder in the MT4 Navigator window.

5. Click on the Experts Advisors folder, find the expert you've just inserted and drag it on the chart that you want to use it with.

6. A window with the Expert Advisor's setting will be opened and there you can fill all the parameters of your "robot".

7. Don't forget to tick the: Allow live trading in the Common tab of your Expert's settings.

8. Close the settings window and if you want to begin trading with your Expert Advisor, click the: Auto Trading button of your MT4 platform.

9. If you see a happy smiling face in the upper right corner of your chart, then you are OK.

10. If you want to avoid internet and power outages, it is strongly recommended to use a VPS service for your automated trading.
