As far as I remember it, if it is not changed, they get an invitation to produce a Darwin from a Tradeslide account and just have to select a three digit code. Then the process starts without any additional agreement about communication.
The trader also does not produce and trade the Darwin, Darwinex does that with the trade manager.
So the trader behind a Darwin (or any other community member) giving recommendations for buy and sell a Darwin gives recommendations to a foreign financial product without a license.
Besides front running is not possible with Darwins, it is the same as on other platforms recommending stocks. The legal background for that? Besides front running is forbidden, I don’t know.
