Using multiple Expert Advisors (EAs) on Darwinex may reduce the likelihood of being detected for correlation, but it does not guarantee it. Darwinex uses sophisticated algorithms to detect correlated trading patterns, which means that if multiple EAs produce similar trading signals, the system might still identify the correlation.
It is best to use a different robot that is probably not used much on Darwinex because if you use a popular EA and they understand that there are a lot of accounts with the same robot, they might not allow both to withdraw any payouts. In this case, to make it individual, make sure to just use a unique robot, e.g. change magic number, modify the TP and SL and other properties slightly.
