These are the results from the EAs I created last weekend using Expert Advisor Studio, I am using a system similar to Alans to create a and validate the EAs, but I do spend a lot of time looking at the reports to select the best ones to put on demo.
Here is the chart showing the return per day.
These are the pairs that the EAs traded.
I have not gone live yet, as I am still working on and refining my process, and the results are getting better from when I first started a month ago.
