I hope you require the investor to sign an LPOA. Otherwise, there's about a 95% chance the account owner is violating his broker's TOS. This means that the broker would be justified in canceling any profitable trades.
3% per day not compounded would be 15% per week. If you trade 50 weeks per year and NO compounding, that would be 750% per year. If we compound weekly, that's 1.15^50=108,365% per year. If we compound daily, that's 1.03^250=161,922% So, each dollar would turn into over 150,000 dollars.
A company that could do this for a few years would own the world.
Never trust a forex account manager who won't give you investor access to a LIVE account that he's been managing for at least a few months. If he doesn't have a live account of his own that he can show you, why would you even think if giving him the ability to trade for you.
Please read this before placing 1 cent into any managed program or giving anyone access to your account:

OK, so how can a company pull a stunt like this in the short term?
A couple of ways:
1. VERY high risk trading. Use that leverage to the hilt, and if the market goes your way, you can get phenomenal returns. If the market turns against you just once, you get wiped out.
2. Moderately risky trading with hedging between client accounts. It's simple. If you have 16 clients, you make a large long position for half and a large short position in the same pair for half. If he price moves significantly, then half of your clients lose a lot. The other half do well. A few of the losers are gullible enough to believe whatever lame excuse you give for your "first loss ever in your perfect trading record" and let you keep trading or even to add more money to their accounts. The winners pay you a nice fat percent of profits. Some add money, others invite friends in. You do it again. Half get hurt, half pay you. If you start with 16 clients and can get 8 new clients per month, you can do this for a very long time.
If you crash and burn too many accounts and the word of your scam gets out, that's ok. Open another free website and use another gmail, yahoo, or hotmail address and start over with a whole new identity. Then just start making posts in more forums with your unsubstantiated claims of trading greatness.
