Inside The Trader's Brain: Decision-Making and Emotional Arousal
For years, behavioral finance researchers have been aware that people's decision making is greatly affected by how choices are framed. For instance, the same monetary bet framed as a choice between a certain vs. risky gain and a certain vs. risky loss elicits very different choices. (We tend to take certain gains, but will seek risky losses to avoid certain loss). Studies using functional magnetic resonance imaging (fMRI) find that we expend less cognitive effort in taking a sure gain than in choosing risky gains, sure losses, or risky losses. It may well be that traders don't let their profits run simply because they take the easy way out cognitively. Conversely, traders may be reluctant to set and follow stops because of the greater cognitive effort required.

It turns out, however, that this taking the easy way out and avoiding difficult decisions may not be a function of laziness. A very interesting investigation coming out of the Institute of Neurology at University College London finds that the framing effect on decision making is mediated by an emotional center within the brain: the amygdala. This is the same brain center that cognitive neuroscientist Joseph LeDoux has linked to our response to stress and trauma.

The implications are significant. When blood flow is directed away from the brain's executive center, the frontal cortex, and the amygdala and associated emotional centers are activated, we are likely to underutilize those executive functions--reasoning, judgment, planning--and respond to our (emotional) framing of choices with a lack of effort. Going with our feelings might just be the reason we don't think through our choices.

It is also likely that we frame our choices differently during periods of focus/concentration vs. emotional arousal. Stressful episodes in the market, activating the amygdala, are likely to elicit a framing that is different from the careful trade planning we conduct when we are cool and calm. Research, for instance, finds that fear and anger color our decision making about preparing for terrorism-related risks. Emotional factors have also been found to color decision making about economic choices.

This helps to explain why I have found biofeedback to be extraordinarily helpful for traders who experience emotional disruptions of decision making. By working with traders in stressful situations and having them control their level of arousal during these episodes, biofeedback enables them to retain access to their executive capabilities. In a very important sense, successful traders train their brains for accurate decision-making under stressful circumstances.

Sometimes, looking back on our trading decisions, we wonder if we were in our right minds. How accurate that concern turns out to be! Some of the best trading psychology interventions are the ones that keep us in our right minds as we make decisions under conditions of risk and uncertainty.


Also found this paragraph from his August 4, 2007 post:

...If you're going to trade, do it the right way. Don't traumatize yourself. Observe and research before you trade; practice trading small and in simulation mode before you put your capital at risk. Don't abandon your day job until you have a track record of consistent profits across various market conditions. Trade less, not more: emphasize the high probability trades and keep your capital safe in the interim. Forget about riches and don't put yourself in a position where you need to trade large and often to make a living; work on covering costs consistently and managing risk. If you don't see objective evidence of an improving learning curve after a year or two of consistent effort, consider the possibility that your talents lie elsewhere.

Trading may or may not produce gain, but it should not be a continual source of pain. No one has ever traumatized themselves to success.


And this from today's post:

Traders don't fail because they lack the right setups or because they weren't born with the right trading personality. Traders fail because they do not survive their learning curves: they put their capital at risk long before they have developed necessary skills and expertise. Simulation-based learning is a way to accelerate that curve and reduce the costs associated with the inevitable mistakes made by learners.

Dr. Brett's Blog- Thick and rich and tasty...

I continue to mine Dr. Brett's blog for wisdom and guidance. However, one doesn't have to mine when the treasure is laying on top for you to see. Such is the case with today's morning post. I won't recap or offer commentary, it stands on its own. From it, I am clicking on his recommended links at the bottom. I just finished the "Implicit Learning and Trading" link to his August 27th, 2008 essay entitled, "Implicit Learning and the Unattached Mind." It is outstanding. This ties quite nicely with Scott Farnham's blog post of August 3, 2009 ( http://www.fearandgreedtrader.blogspot.com/2009_08_03_archive.html ).

I'll be moving on to the other links after this post.

If you are not reading Dr. Brett, you are doing yourself a great disservice.
