The portfolio profit is being calculated like this:
A newbie investor receives a share of the profit of this portfolio in proportion to their contribution after deduction of the manager's commision. (this commision is being set by the Portfolio Manager in the Conditions section for joining the portfolio)
The Portfolio Manager gets the whole amount of the profit from his share in the Portfolio, plus the commission for managing the newbies' funds after the deduction of the platform's commission. The Safinus platform, in its turn, receives a 10% from the commission of the Portfolio Manager. Hope this information clarifies a thing or two
