No this is not easy at all.
First of all, the systems are not scalable that way, at least my kind of systems. And, considering my portfolio of strategies, there are volume limits in the markets that would cause trouble to them.
My systems are targeted on specific instruments so I can't simply add underlings to them to add money in the market and, on each market, there are capacity limits (imagine to enter a trade on Crude Oil with 1000 contracts... you would cause sort of a flash crash!)
In addition to this there are many constraints that keep a trader from managing money, I mean legal constraints that don't make it easy. You can believe me or not but to get money to trade is awfully difficult in spite of any trophies, the money industry is ruled by other logics, unfortunately.
