It is of course a good gesture and motive by these traders to help others know their opinions in a way to help others in forex trading to use the information for their trading.

But, the provider of the facts should be informed enough to understand that he should not believing too strongly in his position and when he discusses that in public a reverse trend can be created by market markers that are researching on trends.

Accepting losses is going to be pretty complicated and the hesitance or reluctance to immediately admit that we are going in the wrong direction with humility is least seen in all such trade forums.  Anyone that is trying to give out opinions in the trade forums should be able to let their ego away and declare that they are were doing the wrong thing and they will have to warn everyone else that is following the said ideas to play the other way around.

Being able to declare that we are trading and following the wrong side of the market is probably the difficult thing to admit and the next time when you sound out an opinion people might guess if the reverse is true.  A follow up can turn to be with a reverse response when corrections in opinion are given in forex trading.
Under the best conditions we would not prefer to take losses.

Publicly prosecuting a particular trade or the direction of a market will be like making the wrong thing harder and more painful for others to accept. The other participants might even suspect that you are trying to make a market that is favorable for you by giving two contradicting opinions about a trade.

After a certain point due to such psychological fears traders that are public about their opinions would be checking in for valid information to support their opinion rather than accepting it is the reverse due to psychological reasons.

A balanced headed trader is one that does not declare his views in public.  It does not mean that discussions in the forums and sharing of opinions are bad, but it is just that there is an other side of the coin for such discussions.
