WHROEDER The spread is variable but I think that hasn´t impact in the custom criteria result due the optimization isn´t in function of trades but math calculations from indicators that use bid price only. I suspect, that in GA optimization, the program is rounding the result and it could impact the output. The scale of results is in fractions and sensitive to rounding, so to verify if is true, im running now the same test but the custom results are multiplied by 100. When finish, I will post a feedback. Thanks. 

I made a test again but changing the scale of results multiplying by 100 and the results generated by Ga and the result generated individually are matching. So, I think that the difference of the results described above, is related to the fraction scale of results and we can resolve it increasing the scale of results: Individual test: 
Hello
I have a problem with the values returned on tester when I use the genetic algorithm to optimize. Using the same parameter in EA, the return value of the function OnTester() dont match when I compare the test individually with the return value in optimization.
Here is the Step by step:
1First I made a custom criteria to run the optimization:
when P, RMSET, RMSE and nmedio are global variables.
2 I ran the optimization with genetic algorithm and show theses results:
3I select the first result and select input parameter to run the test individually and I obtein the following result:
When we compare the individual result with the declarad result of optimization, we see which the results are diverging.
I dont change anything about the two tests. The time period is the same and paramters too, but the results are diferent. I did the calculation manually and, the right result, is the result from a test that ran individually.
What could be happen here?
Thanks
