Time to shut up some paper traders... (well, most of them shut up when darkhorse came with the posts)
Conclusion first...
It's choice.
Trading decisions are purely non-emotional. But the emotions come in with the lack of confidence in the basis of the decisions you make like:
Will this trade win? Which leads to emotions or opinions like:
Will the market move up or down depending on the pre-determined bias you are holding...
Can this market go higher or lower...
etc. etc.
Just do it - Nike
... is the key to successful trading mentality. But this can be achieved only through cumulative experiences like what Kant (or was it Hume) says....
Simple stuff... weak mind will stay a weak mind.... But the mind always grows when you choose to grow it. 95% in ET aka paper traders are concentrating on the wrong direction. But they choose to move a certain direction because the basis of the direction they are concentrating is an individual compromise of what they percieve their character should be or is. Which is all a choice like what Dr. Phil talks about all the time.
So... it's all about being honest with who you are, first... Then being a flexible person ( it's not flexible when you are trying, willing, or thinking to be but just being flexible )...
Another point is you become emotional with your trades because you care. It's ironic that the more passion you have towards trading, the more pitfall are offered like the Zen saying, " Everything should be done effortless." It's a matter of how you focus your passion where you don't affect your trading. Again, simply action.
Final point would be, all trading psychology seminars, books, articles, gurus, and etc. are BS. It's either you are or you are not...
Well, just my 2 cents.
