Emotional Resilience – The very successful traders have a great attitude about losing. They know it’s going to happen. They don’t take it personally. If anything, they try to find learning experiences from losses. Elsewhere I have written about how good traders view a losing trade as “paying for information”. A trade with an edge that doesn’t go their way either tells them something important about the market, or it tells them something about their execution. Either way, it’s a potential learning experience. Resilience means that the excellent traders trade well out of a hole. They can be down money for day, week, or quarter and continue to make the same good trades they would normally make. 
Creativity – We normally think of creativity as a trait that belongs to artists, but it also is quite noticeable among traders who have been successful over many years. They find edges in the most unlikely places. They look at interesting relationships within the market they’re trading, and they find unique relationships from one market to another. One trader very recently told me of a strategy that exploited the way one market was priced related to a similar market at certain time periods. I would have never thought of that idea in a million years. He was making consistent money from the concept.
