When I was a clerk on the floor of the CME in the mid-90's, soaking up everything I could about trading, I kept coming across the phrase, "You have to have an edge." For some traders that simply meant standing near the pit broker and being on the right side of order flow because they provided liquidity, and this meant they could always buy on the bid and sell on the offer. Easy, but not really trading I thought.
