I wouldn'e be so bold as to say we attracted the best, if anything I found a shortage of people with the qualities I was looking for. Every time we ran an Ad. we would get 500 odd apps. from people who thought they were just applying for a 'job'. I found that having been around a lot successful traders having an informal and relaxed chat with applicants I could hone in on similar attributes that I was looking for. I only ever would do this with about 30 before whittling it down to 8 or so.
These are young people on average sub 26. I haven't come across many people that age who would want to spend all day everyday at home. The camaraderie aspect is a big aspect. We had a lot of fun together. The biggest factor is that the way we trade you need speed, that speed is not available at home, unless you invest a considerable sum of money. In the office you get an analyst squawking news and 30 pairs of eyes watching the market like hawks spot more then one pair. That said, the guys now trade in places such as Spain, South Africa, Canada and the US. Nothing I would describe as exotic but I am sure they are happy. I myself trade at home every now and again, but I just prefer the office, I feel that will change though as my needs and wants mature with age.
The word tighter is maybe not the correct word, I cannot quantify the term statistically. However I feel that as a screen based futures trader who has traded day in and day out for the last five years that the moves are not as dynamic and free flowing now as they were back in the infancy of screen trading. Economic releases have less short term impact and the daily ranges are smaller. However getting back the question. I do believe that I could replicate the result over the next four years or indeed any time frame although the actually success rate may trend lower. Why so? because in the same way that I am confident that every day I sit down I am going to make money, then by the same measure I think I can pick quality candidates, and give them the support they need to develop into successful traders. I will not be so bold as to speculate as to the the degree of success that they would obtain though.
Hope that goes some way to answering your questions.
All the best
