This is really getting funny now. Did you read my last post?
That study was directed at daytrading firms where people trade from an office, and most definitely did include pro firms. Anyway, ain't no difference between some one who gets a license or somebody who doesn't have one, has nothing to do with earning substantially more over time than you're losing, and accomplishing that after all relevant costs, and still having enough over to pay the rent.
Anybody who says that that study is not accurate should prove it.
Everything else is just unfounded marketing.
The GAO report said day-trading firms admitted that most clients lose money initially, but contended that those who stay in the game more than six months make profits.
"This claim directly contradicts the most extensive study on profitability [of day trading], which was conducted by the Washington State Department of Financial Institutions," Levin noted.
I found a thread by a guy called Hitman who traded for a so called pro firm where he more or less exactly substantiated the findings of that study.
That is just plain old reality.
