I hate engaging in these mindless discussions but i just had my coffee and here's my 2 cents. Perhaps it's not a question of fear that one may reveal too much info but a question of proper motivation. What incentive is there for me to post a few trades so that even if they all turn out winners some anonymous poster can say kudos?
This subject comes up constantly on ET and over the years i've noticed that you always get the naysayers matched up against the braggers and the discussion goes nowhere. I personally know a handful of independent traders who make anywhere between 1-5m per year so 5-20k means a good day's work for them. So why not offer them let's say half of a day's work and in return ask to review their statements with matching tax returns and cleared tax payments. Surely a cleared check to the IRS is enough proof, no?
So, If after years of study you are so certain that no one makes money then why not offer proper motivation and see who comes out of hiding. But of course you won't do that because 1) you don't have the disposable income to support such inquiry and, or 2) it won't serve your hidden agenda.
