The site could be more careful about not allowing 'suspicious' signals to be made available. There are too many signals that show incredible results in the first few months only to fall drastically next and even disappear.
Signal providers don't post updates to their strategies or even justification to their actions. There is no possibility of dialog between the signal providers and the followers and, most importantly, no rating system so users can better evaluate the providers and make an informed decision on what providers to follow.
Analisys and statistics tools could also be better, since they are part of the Myfxbook site. For now, there is still a need to have a separate Myfxbook account to have better analysis.
Having said that, overall a better service than similar others.
