One of the things I like most about Darwinex is its resemblance to a normal Mutual Fund, in that the actual decision processes are kept proprietary. The built in rating system seems to be a good way of normalizing results while taking into account so many other factors. The typical MF would do road shows to show off their key traders/managers and answer questions from the sales people and investors about the fund.
As a trader though, I do like how one can look at the account/trader's history in FxBook and get a better feel for how trades and risk are managed. I guess we can't have it both ways and hope the traders here continue to do their own "road shows" to help investors become more confident in the trader and/or Darwin.
As for Mutual Funds, typically, once the fund was established the methodology would not change, even though managers would come and go. Unfortunately, in the Forex world, we see many traders change their strategies due to a series of losses, draw downs or missed opportunities, myself included. I see this as one of the hardest challenges to deal with when looking at Darwins/Traders ... when meaningful communication from the trader is lacking.
