What makes you not to take a signal generated by your system? What other factors do you consider? Overall market, news, fundamentals...? Gut feel ...? Setup doesn't look perfect..?
Good question. As I generally buy pullbacks, there is always some fear in play. If the overall market is pulling back, I may also fear putting too much capital on the line with an increasing number of system alerts, despite the fact that I know damn well that this is typically the time to be very aggressive.
Then there are the reasons stocks are pulling back. (Is this really bad news? Does this analyst know something I don't? Etc. Etc.) Is there widespread fear in the market that's being reported in the news? Should I just not listen to the news at all? (I say listen, my system says DON'T!)
My theory is that there are two main reasons why we let our brain get in the way more often that not.
1. It will happen if we don't have complete confidence in the system we are trading, which so often happens if you are trying to trade a system you didn't develop.
2. It will happen because we all feel we need to "work" for a living, and we think that profits should not come without constant effort. That work ethic is drilled into us for decades of education, and years more of professional advancement. But it is often not supportive of good trading, especially after one has learned the ropes and developed a system that can run somewhat on automatic, if even for a short amount of time.
As with MANY aspects of trading, what we have learned in the past...and how we've even learned to think at all... can often get in our way.
