When I play well, I win.
When I play poorly, I lose.
I usually play well. Sometimes, I do not.
If I play well, I may lose in the short term because I get sucked out on more often than expected, but in the long run, I win. I know, from watching the play of other players, that this is because I have a plan which is good enough that it provides a positive expectation in terms of outcomes over time. My plan wasn't that hard to formulate. Most of my opponents have no such plan.
Every time I make a mistake, I know it almost immediately. I have been playing for a while now and I still make mistakes. It is amazing to me because I have no interest in manifesting the behaviour which characterizes 'mistaken play'.
It is abundantly clear to me that those who will succeed in trading and in poker must be the type of people who, either by dint of effort or by natural inclination, are able to control their actions, and this must extend to non-trading activities. Alexander Elder's comments about people who know what they have to do to lose weight but are unable to do it ring more true every day.
I am eventually going to give daytrading a serious try, and I wonder how it will be then, with real money on the line. I have managed to give up some serious habits in my time, and it was not easy. I like to think of myself as a disciplined person.
The more I think about it, the more I suspect that those who fail at trading fall into one of two easily definable groups. Either they are
a) unable to formulate a plan which provides them with at least a reasonable expectation of a positive outcome over time or
b) unable to execute the plan
This implies that there isn't anything that difficult about trading, which is contrary to what I see written here all the time. It explains why some people can only trade systematically. It means that anyone who can formulate a decent plan and execute it can at least give it a good try. This is what I believe about online low buy-in NL Hold-Em.
But what about all the professional traders who have all that experience, all that knowledge, all those resources, and still lose money? Are they losing because of factors outside of their control or are they simply making mistakes?? This question is pretty relevant, IMO.
Is trading success all in our heads?
