If anyone believes the "zero" prop guys are giving anything away free, then I have some land if Florida for you. We have dozens that came from places like Schonfeld and are quite happy keeping all their profits. The "zero" prop firms do, in fact, allocate overhead and commissions to the traders, many are much higher than you might expect. They also have weird payout arrangements like 1/4 now, and another half in a year or two, whatever.
Our model is exactly like what Bob and I enjoyed on the Trading floors with SLK (Goldman) over the decades.
Now think about this for a minute. If you happen to be successful with "zero" down, within a few months you r account "should" have your money in it, right? Then if you lose that, it's your money that is being lost, right? But when you take money out, you split the cash with the Firm. Independent traders figure that out, and that's why they prefer to be independent.
All the best, and if you can find one of the very rare "good" deals, please forward a copy of your contract, I would like to see it. The contracts that I have reviewed in the past were pretty restrictive. I'm not saying that there aren't any "good guys" still out there, I would just like to know who.
All the best,
Don
