No, the Service takes no investment fees.
But if an Investor has a Referrer ID, then the deposit will be transferred to your account after deduction of 5% from the deposit amount. This fee goes not to the Service, but an investor who had brought the investor, who made a deposit in your Trade Group. At that, your Trade Group should service the deposit in full, 100% without taking into account the fact that you get 95% of the deposit at your account.
The Service has a general referral program equally beneficial for all Trade Groups.
