If he is so "amazing", why would he work for someone else and only get a measly 30% payout? Why not trade his own account and keep 100% of the profits? After a few years of his "amazing" results, he should easily be able to raise money to start a fund (if that is his goal). Then he could be the guy offering out shitty deals to the next "amazing" trader.
Yes. If he's ttruly amazing he should definitely go prop. Big leverage, low capital risk and no this 20K shares a day crap. He can do whatever. If he trades 1000 shares a day and makes $5K, then he gets to keep the $5K. No one deserves a penny of his trading skills but himself.
I love trading, but the one thing most operators in this industry fears is the sun/light...like vampires they operate in the shade. Read about the trader that lost 12 million before anyone found out about it, read about GS prop traders front running, and now prop firms that have 20k daily share requirments and convoluted deals - lol. Also have you noticed that a lot of traders like to trade with the lights off, ever visit Assent, Genesis - lol. Edit: I guess you can say people need to 'lighten' up
