There is a new book on the shelves called "House of Money" where they interview a few traders, including a prop trader at Goldman. It's pretty interesting and he goes into a little of the history of the prop group. From the early days where they were encouraged to take risk. Describes one meeting where the research department told the prop group that there may an opportunity in Spain, it was shot down because one of the traders was just in Spain and when he went out on the town there was nobody at the bars. Now it has progressed into much stricter risk management.
Another story that jumps out is when he this particular trader was talking with one of the new guys. The new guy was up $50 million and worried about his position. He advised him that if he was worried he should take the profit because it was very good for a newbie. He said he would in a second but if he did he would be down $50 million (liquidity!!)
There's a big time FI trader at Barclay's who has a PHD in psychology and likes to hire people with backgrounds outside math (athletes, musicians, etc.)
What I really enjoyed was that almost all of the interviewie's lost huge money at some point in their careers, plus $100 million at some points by doing the same stuff that gets the small timer, hanging on to a loser, moving stop loss, etc. Obviously these guys were able to take the loss, move on, and make enough to cover the loss and then some.
