Funny that at least 3 of the people on these list have already openly admitted to blowing out their accounts. So are you talking trading intelligence or just book smart?
Seriously, it would be hard to pick the most intellegent poster on ET...there are so many. Don Bright is definatly one. So is Nihaba Ashi....... Marketsurfer, Aphexcoil, Nitro, Candletrader, and Tampa are a great combination of smarts and humor. Many more too......I do not think the market attracts a lot of stupid people....or at least they do not last very long.
