I've been hesitating to make this post since the subject of suicide alone is so damn controversial. But I think it merits discussion since the suicidal tendencies are readily apparent in trading. Suicide is an willful act of ending one's own life. According to Wikipedia, there are various reasons associated with the risk of suicide including but not limited to depression or mood disorder, substance abuse, and socioeconomic factors. While external circumstances, such as a traumatic event, may trigger suicide it is more likely to occur during periods of socioeconomic, family and individual crisis. Such crises induced by acute level of stress is not altogether an alien concept in the world of trading. Every day, we make our tortuous round from heaven to hell and back. Some folks make a killing while others inevitably lose everything and then some. But why do certain traders engage in particularly destructive behavior that ultimately blows out their account and end their trading career? For example, I've seen traders taking on excess leverage while they were in deep hole and yet they avoid using any leverage when they were in black. What catapults them over the brink knowing well that any misstep would cost them dearly? By no means is this a scholarly debate but I do encourage any professional opinions.
