I give this trader a whole ton of credit for sharing this with me, but even more credit for some of the self realization that occurs. The problem with overconfidence in the markets is that the majority of the time, you don’t know you’re being overconfident until it’s too late. Taking an account from $4,000 to $20,000 is an awesome thing; however, when it is being done without an actual strategy/system, it’s only a matter of time before the market takes back what it gave you.
