I think the first personality trait of a good trader is knowing whether he has the setup to be a good trader (capital, intellect, and access). And then how you can go about learning to be a good trader. this is hard because 1/2 the world will tell you, you can do it. The other 1/2 will tell you, no matter what, you can’t.
I believe that consistency in learning, strong determination and hard work makes a trader successful.
