Gargamel: thank you for this explanation. It is a jungle! You are right i will modify my crietria thanks to you. I will add : amount of money invested by the darwin trader superior to the amount invested in his trading account. That’s an important filter because by doing this the darwin trader is exposed on the risk of the darwin. Great idea. Also i will modify « high return » to only « positive return ». So, it is end up to 4 criteria : var under 3.25% + 2 drawdowns under 10% + positive return + trader exposed on the darwin.
