At heart, a forum with only one opinion on a subject is going to die out. Especially when it concerns a subject like trading. If you're only told that whatever you say is right and you should do it, there is no opportunity for improvement or development, either at the forum or later through other routes.
Its no wonder trading forums must show a multiplicity of opinion. There are always at least two viable opinions on the potentiality of any single trade - buy because price is high or sell because price is high: both are legitimate responses to a price history.
