All the trades from the Expert Advisors are done with a fixed lot. There is no money management or other risk accumulation element in the systems. The data on the charts are updated every hour and it shows how many points are won by the systems. There will be a constant process of adding new expert advisors with good expectancy and removing expert advisors with bad results.
Even if you choose the best Forex EA from the list, you don't know how it will perform in the future. That's why the best thing you can do is to choose good experts with low correlation and create a portfolio of at least 10 expert advisors. Then you can monitor their performance, and substitute the ones who don't meet your expectations with others.
