Some traders in the Forum shared that they use the Portfolio Experts to save time on the Demo account to place 100s of EAs.
How does this work? If you want to test 200 EAs on a Demo account, well, first you can not in one account with single Experts, but with the Portfolio Experts you can group them to 10 Portfolio EAs, 20 EAs each, and place them just on 10 charts.
From there you can follow the stats and see which strategies perform the best, and use them as individual EAs, or group them in one Portfolio EA.
