A friend of mine offered me to open a small trading group in the near future, like a max. of 10 traders, including myself and him. And the rest will be green guys who will be trained from scratch. I would like to ask some advice regarding the overall risk parameters and how should they be managed for the new guys?. I mean, take 5-10k per person and treat them as "education costs" for their first year from the begginin?, or manage the risk separatelly with some margin for their losses in the trading group itself including us?.
