Some brokers/providers may provide basic trade replication services. For other brokers, there are FFA features that may fall under Prime brokerage or Institutional with much higher minimum balance/liquidity requirements. You will have to make calls and talk to account managers, so they can offer you the package that you need. At the least, educate you on what you need. There are operational requirements to managing other people's money that could take up more time than actual trading and investment selection.
