A Managed Futures account is like having your own trading account.  The only difference is that unlike having your own trading account that you yourself make discretionary trades on, a managed account gives a trading advisor or CTA like PHG power of attorney to trade that account on your behalf.   Power of attorney only gives the advisor power to trade your account it does not give them power to handle your money, brokerage-clearing firms are for this.

Many beginning traders are unfamiliar with strategical tactics for long-term equity growth and tend to lose much if not all of their investment trying to trade on their own.  This usually occurs because they lack the discipline to implement a good long-term strategy without violating the systems rules and therefore causing much larger drawdowns and fewer chances for profit recovery and a nice even equity curve.

PHG has realized the power of implementing computer traded strategies because a computer doesn't have an emotional response to loss.  A computer will not take profits too soon or get out of a losing trade too fast in order for it to recover unlike the way a human trader will.   It must also be noted that computer trading systems are not perfect and that losses are still very likely and that you may lose most if not all of your investment.
