You know what, it really doesn't matter whether these claims are real or not.
Only the posters know the real story, and who knows, maybe some of them trade under two names, with two bankrolls, long and short the same stocks/futures and only talk about the winning side. Shades of Hillary.
Don't let that get you down. It might be true, but it's just as possible it's BS. And for everyone who is making money, there are a lot more who are blowing out, losing their ass, or struggling to breakeven.
I'll be sure and post when I start pulling in 100g's a year.
