a question about optimization

New comment
 

When I want to optimize some parameter's value by select Optimization in tester, i will get the optimization result in the list of Optimization Results.

then I select one from the list of results, and I set the parameters according to the selected result and test it again;

What is surprising is that the maxinum drawdown is different but the profits are the same.

I want to know why.

Thank you!

There is probably, some others settings/parameters who are varying. Can you publish your settings and results ?
