I thought I would start this thread to discuss abnormal psychology and how it could relate to trading. Since it is a well known fact that the class of those who make money in the market are a minority, it would seem that these individuals possess a way of thinking that is different from most people. What better place to look for different thinking than the "abnormal". In this thread I would be interested to hear from people who themselves have diagnosed (or strongly suspected) abnormal psychology and how it relates to trading. Also from psychologists and their thoughts on this topic (or corrections in case I posted some inaccurate information). Many people automatically assume that disorders such as Aspergers, ADHD, Schizophrenia (or others) are found in people who have an inferior ability to deal with reality. While in some cases this may be true, traits from these disorders can give rise to some truly amazing people (im not going to list them there are many of them if you are willing to do a search). Take for instance here on ET an individual named Acrary who has stated that he has ADD. All you have to do is read the first 10 pages of this thread to tell that on a usefullness of posts scale he would score in the upper 99.9th percent http://elitetrader.com/vb/showthread.php?s=&threadid=33654&perpage=6&pagenumber=1 Altho the theme of ADHD is that of an inability to do one thing for very long, individuals sometimes have the ability to hyperfocus on one subject. Aspergers also has some characteristics that would be desirable in trading such as strict adherance to routines and activities that are restricted and repetitive and are sometimes abnormally intense or focused. Schizophrenia is complex and can manifest itself it different ways but a general theme is that there is a loosening of associations between concepts which can unfortunately lead to psychosis but also increased creativity and ability to put things togther in strange ways. Edit: in anticipation of jokes to come I would like to state that schizophrenia has nothing to do with multiple personalities.
