voting off would not be done by a majority but by a minority of VOCAL ignorant. no opinion about majority
The assumption you make is the problem with your thinking. I don't know about you, but I don't know any trend followers that make a good living at this. That is usually where beginners start their journey, because it's a simple concept. Although, trend following is extremely difficult to implement and probably the hardest trading style on the psyche due to long drawdowns. For this reason any trend follower could detail his entire system on ET and it wouldn't make a difference 99% of the time. There is plenty of liquidity for this style because entries wouldn't all hit the market at the exact same time. On the other hand if you employ the type of trading that most prop shops are teaching (filters, opg, liquidity trading, etc.) then liquidity will definately become an issue at some point. Orders all hit the market within seconds of eachother. The guys on ET making a good living are mostly using these types of strategies which is why you never get journals from the best traders on ET. One exception would be Lescor who is very open about opg's.
It requires a belief that one is smarter than the market to make any trade at all. After all, if the market is smarter than you, then the current price is efficient and your trading will lose money after transactions costs.
You make two unsupported statements of opinion as fact. You'll have to demonstrate that one has to believe he's smarter than the market in order to place a trade, also that there is some connection between the "smartness" of the market and whether or not a given price is efficient.
any time you enter the martket you are making a call...( i dont care what you want to call that; predicting, speculating, reacting, going with the trend ) ...in the end you take what you know and make a 'BET' that what you know is going to be correct.....
