What are the personality traits of a successful trader? In outward style, there seem to be two opposites. One is quiet, reserved, and not normally noticed at a gathering. The other is an extrovert, flamboyant, fun-loving eccentric: something of a renegade. But inwardly, they are alike.
In college both types spent a lot of time at extracurricular interests, and both had irregular grades – A’s in some subjects, and C’s in others. Usually they are neither loved nor hated., and they adapt to new people and events with ease. They are extremely determined and extremely individual, never asking for favors or help. They may ask your opinion and read many forecasters’ views, but rarely act on anything but their own decisions.
They are honest to the bone, living by their own wits and courage. Some are vocal and curse at losses or themselves, and sometimes yell and scream at executions; but generally, this is just an outlet for tension. All view profits and losses as their own responsibility, not anyone else’s problem. The best ones are usually internal; they hold hurts within and force a smile when taking losses. Most pros talk about their losses, not their profits. They brag not about their winners, but how they lost.
