Hi Zoran,
The beauty of having a portfolio of EAs’ is when a few of the EAs’ are losing the other EAs’ in the portfolio will most likely be profitable and thus compensating for the losing EAs’ to keep the overall portfolio profitable. Further, the EAs’ in the portfolio that are currently losing will most likely be profitable in the days and weeks ahead and some of the EA’s that are profitable today may be losers in the weeks ahead. Basically, the EAs’ in a portfolio will move up and down in profitability in the weeks ahead while the portfolio as a whole will remain profitable. In my opinion the only time a portfolio should be modified i.e. removing an EA from it would be if the portfolio as a whole is underperforming your expectations or is losing. Bottom line, the purpose of using a portfolio of EAs’ is not to look at the performance of the individual EAs’ within the portfolio, but look at the portfolio as a whole.
To answer your question as to how to know which EAs’ in a portfolio are losing the easiest way to do that is to keep a list of the EAs’ Symbol and magic numbers in a text file. Then in the days and weeks ahead you can look them up in the Prop Firm or Top10 apps and see how they are currently performing. Doing this you can identify which EAs’ are losing. You could then recreate your portfolio eliminating the losing EAs’ and maybe replacing them with the current top performers.
I believe the other part of your question has to do with the profit of XAGUSD being much larger than the other EA’s. This indicates XAGUSD is having a major influence in the overall profit of your account. To reduce this influence you can reduce the lot size. It looks like XAGUSDs’ profit is about three times that of the other EAs’ so you could reduce the lot size of XAGUSDs’ portfolio to 0.01 lot.
