Yes, I don't believe it's a mystery. Correct me if I'm wrong, but I thought he has posted he is a manager of the Chicago office of VTrader Group. I looked at their site recently as I'm thinking of going back into equities and found the site to be very professional, with an ample amount of info on the firm. I was actually thinking of giving them a call to see what requirements they have for equity traders and if they offer training that is mentioned on the website.
