Hi Wayfarer,
Once you have exported (downloaded) your Portfolio EA, copy it from the downloads location. Then on your platform, open the Data folder from the File menu, navigate to MQL4/Experts and paste it in the folder. Close the folder, then right click on Expert Advisors in the Navigator window, and once it complies, enable Auto Trading on your platform, and drag the Portfolio EA onto your chart. Make any changes you want to – lot size, base numbr, etc. and you should be good to go.
You can remove the EA that is not performing well by loading the Portfolio EA into the Validator in EA Studio, loading the strategies and deleting any that you no longer want to use. Then repeat the process of attaching it to your chart.
Have a look at the user guides below
Thanks,
Ilan
