Quote from sculptor66:
I don't think so. If I remember correctly, there are some studies about professional gamblers (e.g. poker players) and even traders out there which confirm that the successful ones are mostly INTJs and some off them INTPs.
However, while being an INTJ seems to be favorable for being successful as gambler or trader, it doesn't mean it's all that's required. Still, most INTJs will fail at trading.
But I think that other personality types - especially the "feeling" ones are even worse off at trading than INTJs. While maybe 80-90% of INTJs may fail at trading, I bet that the failure rate for the "feeling" types is even closer to 100%.
I'm just joking around... I'm an I or ENTJ, depends on the believe that you can change over the years from intervert to extravert, and I know that Paul Tudor Jones is also an INTJ as many others well known traders...
