Sean Hendelman is the co-founder and CEO of T3 Companies. T3 is one of the larger proprietary trading firms in the U.S. And incase you’re curious, the three T’s of T3 stand for; trading, training and technology. A few of the things Sean and I spoke about, include; how he got his start, how he lost all his money twice—and why it was a worthwhile experience (in hindsight), and some of the great lessons he’s learned from the business of trading. Even as CEO today, Sean is still very hands on with T3’s automated trading, so we also had an interesting conversation around this—some of his comments and views may actually surprise you. And hand traders, need not feel neglected, because there’s something in this for you to!
